99ecfd3b52 apple: Convert GN libs lists to frameworks.
GN recently added support for Apple frameworks to link, rather than
overloading the libs lists. This pulls .frameworks out of the libs
lists, so that GN can stop supporting .frameworks in libs in the
future.

4145699874 win,linux: implement attachments support
Implemented the AddAttachment(), InitializeAttachments(), CleanDatabase() functions
on Windows.

Added attachment=FILE_NAME option to the handler, and
"attachments" argument for Windows and Linux to StartHandler function.
On crash it will create the corresponding attachments in the database
and copy content of the specified files to the database.

161bfed35a Remove/replace unnecessary includes of logging.h
If the file just needs the CHECK/CHECK_OP/NOTREACHED
macros, use the appropriate header for that instead.
Or if logging.h is not needed at all, remove it.

This is both a nice cleanup (logging.h is a big header,
and including it unnecessarily has compile-time costs),
and part of the final step towards making logging.h no
longer include check.h and the others.

032f1aecc2 Include-what-you-use related to logging.h
Add direct includes for things provided transitively by logging.h
(or by other headers including logging.h).

This is in preparation for cleaning up unnecessary includes of
logging.h in header files (so if something depends on logging.h,
it needs include it explicitly), and for when Chromium's logging.h
no longer includes check.h, check_op.h, and notreached.h.

DEPS is also updated to roll mini_chromium to ae14a14ab4 which
includes these new header files.

a8ff626764 Add a bunch of missing string.h includes.
There are a few files in the tree which use various functions defined
in string.h (memcpy, strlen, strnlen, memmove, etc), but never include
the necessary header file. After I've recently updated one of my systems
to a newer glibc version (2.30) this code failed to build. Adding the
missing includes fixes the problem.

The undeclared functions for each file are:
* simple_address_range_bag.h - memcpy
* http_multipart_builder.cc - strlen
* minidump_context_converter.cc - memcpy
* ptrace_client.cc - strlen
* http_transport_socket.cc - strncpy, strlen, memcpy
* process_memory.cc - memchr
* log_output_stream.cc - strlen

a45eea40fc Update gtest to e3f0319d89f4cbf32993de595d984183b1a9fc57
I’m most interested in picking up 1b3eb6ef3462, “Explicitly define copy
constructors used in googletest tests.”

This also reorganizes files and rewrites text to refer to this project
as Google Test and googletest (and Google Mock and googlemock), as it
prefers to be known. Some filenames are left at gtest_* following the
precedent set by gtest itself. For example, #include "gtest/gtest.h" is
still used, so #include "test/gtest_death.h" is retained too.
gtest_all_test OutputFileHelpersTest.GetCurrentExecutableName hard-codes
the expected executable name as gtest_all_test among other options that
do not include googletest_all_test, so test executables retain their
names as well.

adfd94a357 ios: Use compat to provide items missing from the iOS SDK
This updates the way that the .defs files added in 1bfd7d06ed60 are
treated, by putting them in compat/ios, using compat as intended. The
.defs files in compat forward, via #include, to the ones in
third_party/xnu. Additionally, compat/mac is enabled for iOS, as
everything in compat/mac is sensible on iOS, and will have no effect
when rendered unnecessary by the iOS SDK.

This also changes util:mig_output to a static_library instead of a
source_set. I don’t think there was any reason for it to have been a
source_set to begin with. static_library is preferred for nearly
everything.

64b8791f45 ios: Build util/mach/exc_server_variants.cc, support code, and tests
This makes UniversalMachExcServer available on iOS.
UniversalMachExcServer is the foundation for a Mach exc and mach_exc
server.

Some code in UniversalMachExcServer needs to be evaluated to ensure that
portions that run in the same process that has sustained the exception
are safe to do so at that time. For example,
SimplifiedExcServer<ExcTraits>::Interface instantiates and appends to a
std::vector<>, which is generally unsafe in this context. However, that
code responds to exc requests. The mach_exc equivalent,
SimplifiedMachExcServer<MachExcTraits>::Interface, does not use a vector
at all.

This also enables support code in the form of CompositeMachMessageServer
and UniversalExceptionRaise, all of the tests for
CompositeMachMessageServer, and most of the test for
exc_server_variants.cc. The multiprocess-based exc_server_variants tests
remain disabled on iOS.

1bfd7d06ed ios: Run mig with the correct SDK and architecture
mig was being invoked without any -arch argument, causing it to assume
the build system’s native architecture, which would be x86_64. This is
not correct for iOS device builds, which use arm64. The -arch argument
must be plumbed to mig for correct behavior.

When building for iOS, mig was being invoked without any -isysroot
argument, causing it to use the root for the build system, which runs
macOS and not iOS. The macOS SDK doesn’t include the ARM definitions
needed for iOS device builds.

<mach/exc.defs> and <mach/mach_exc.defs> depend on a small number of
other .defs files to provide definitions of standard types. All .defs
files are absent from the iOS SDK. These .defs files are borrowed from
xnu and placed in third_party/xnu. An additional --include argument is
added to allow mig to locate these files.

3e748e9c4e ios: Provide a copy of mach_exc.defs and run mig on it
This updates (and corrects) 8dbbaff2e1a5, which added exc.defs, by
adding mach_exc.defs too.

The difference betwen the exc and mach_exc subsystems is that the |code|
parameter is int[] in exc and int64_t[] in mach_exc. Many exceptions
carry the exception address in code[1], and a 32-bit int results in the
exception address being truncated in exc. No information is lost in
mach_exc, where a 64-bit int64_t is used.

In 8dbbaff2e1a5, I misremembered the type of the |code| parameter as a
type derived from uintptr_t, such as vm_address_t, an integer as wide as
a pointer. I was wrong, and mach_exc is necessary. I also noted that
Apple normally forbids mach_-prefixed interfaces in favor of the
prefix-less ones for the reasons I mentioned, and that, all else being
equal, it was desirable to adhere to the spirit of that convention.
Because neither exc nor mach_exc are available in the SDK, it’s moot
from a technical perspective, as we need to provide our own stubs either
way.

4cb79941fc ios: Build four more Mach message and exception utilities
This enables the following code in util/mach on iOS:
 - exception_behaviors.{cc,h}
 - exception_ports.{cc,h}
 - mach_message.{cc,h}
 - mach_message_server.{cc,h}

Only the ExceptionBehaviors and MachMessage tests are built, because the
other two are tested by multiprocess tests that won’t run on iOS.

The AuditPIDFromMachMessageTrailer function from mach_message.h is
excluded on iOS because it relies on <bsm/libbsm.h>, which is broken on
iOS: it depends on <bsm/audit_record.h>, which is missing from the SDK.
Additionally, the BSM function that Crashpad uses, audit_token_to_au32,
is marked as unavailable on iOS. Crashpad uses it on macOS to
authenticate Mach messages sent by other processes, but this is moot on
iOS.

8dbbaff2e1 ios: Provide a copy of exc.defs and run mig on it to generate exc stubs
The iOS SDK doesn’t include a copy of <mach/exc.defs>. It only provides
<mach/exc.h>, which is just the user-side header. To obtain declarations
and implementations of the server-side stubs, a current copy of
<mach/exc.defs> is added to third_party, and the mig action in util is
updated to use it on iOS.

The three other mig subsystems that Crashpad uses are not brought to
iOS:
 - mach_exc is identical to exc except it always uses 64-bit quantities
   for addresses in place of exc’s use of quantiies sized for native
   pointers. Because all iOS work is limited to a single process, there
   is no need to consider cross-process operation with variable bitness,
   so mach_exc is unnecessary. We’re also only targeting 64-bit for iOS,
   so exc will always suffice. This follows the spirit of other
   mach_-prefixed routines on iOS, where Apple forbids mach_vm_read to
   user applications but permits vm_read.
 - notify is primarily used on macOS in the Crashpad handler process to
   receive a no-senders notification, which is used to trigger handler
   shutdown when it has no more clients. This is not believed to be
   useful to Crashpad on iOS, which is restricted to single-process
   operation.
 - child_port is a Crashpad-specific subsystem used to pass Mach rights
   between processes, but is similarly useless when restricted to

ba24acb86c ios: Split bootstrap out from mach_extensions
mach_extensions is sensible on iOS, but bootstrap is not available
outside of macOS. To allow mach_extensions to be used cleanly on iOS,
the bootstrap code is moved into its own macOS-specific file.

122a400d7b ios: Enable (and test!) more of util and test
This builds some code in the util and test libraries on iOS that was
previously excluded. It also enables tests for this code, and other
tests that it was possible to enable either previously or as a result of
this change.

Previously, crashpad_util_test ran 178 tests from 46 test suites, and
crashpad_test_test ran 2 tests from 2 test suites. Now,
crashpad_util_test runs 284 tests from 62 test suites, and
crashpad_test_test runs 6 tests from 4 test suites.

The related .gn files also suffered through a slight cleanup.

b2fd7d5307 [ios] Bring up first half of UncaughtExceptionHandler.
When code raises an Objective-C exception, unwind the stack looking for
any exception handlers. If an exception handler is encountered, test to
see if it is a function known to be a catch-and-rethrow 'sinkhole'
exception handler. Various routines in UIKit and elsewhere do this, and
they obscure the exception stack, since the original throw location is
no longer present on the stack (just the re-throw) when Crashpad
captures the crash report. In the case of sinkholes, trigger an
immediate exception to capture the original stack.

The is an improvement over the alternative,
NSSetUncaughtExceptionHandler, which passes along the stack frames, but
not the stack memory contents and full exception context itself.

The details of what happens after a fatal exception is triggered are
unresolved in this CL.  For now, simply call std::terminate.

This code was inspired by chromium/src/chrome/browser/mac/
exception_processor.mm.

c4cc4e6ac9 android: initialize signal dispositions
Bionic installs signal handlers which request crash
dumps from Android's debuggerd, but there are errors
in how signals which aren't automatically re-raised
are handled on Marshmallow (API 23).

Before requesting a dump, Bionic acquires a lock to
communicate with debuggerd and expecting imminent
death, never releases it.

While handling the dump request, debuggerd allows
the dying process to continue before
ptrace-detaching it. So, when Bionic manually
re-raises a signal, it is intercepted by debuggerd
and the dying process is allowed to live.

Bionic restores SIG_DFL for the signal it's just
handled, but if a different crash signal is later
recieved, Bionic attempts to reacquire the lock to
communicate with debuggerd and blocks forever.

Disable Bionic's signal handlers for these signals
on Marshmallow.

7ed4d5c454 arm: Properly mark _ZN8crashpad14CaptureContextEP10ucontext_t as %function
lld wants to remove bl/blx substitution for non-function symbols
(https://reviews.llvm.org/D73542). GNU ld apparently already doesn't
do it.

Since _ZN8crashpad14CaptureContextEP10ucontext_t wasn't marked as a function,
chromium's thumb code would then branch without mode transition into
crashpads non-thumb assembly (in arm32).

So mark the symbol as function, so that things work even if that patch
relands. This should also make things work with GNU ld, though I haven't
verified that it was broken before and works now.

I also did this for aarch64 since it seems like The Right Thing To Do
(assuming the assembler accepts it, which I also haven't checked --
the CQ will hopefully check that).
