5969d6b1eb android: NDK r16 compatibility
This updates build/gyp_crashpad_android.py to define the
android_api_level GYP variable whenver unified headers are in use.
Previously, it was only set when compiling with GCC and using unified
headers. This pairs with https://crrev.com/c/804574 to allow proper
detection of when _FILE_OFFSET_BITS=64 would be inappropriate.

Since there’s no longer any possibility of using a 64-bit off_t with API
< 21, this also drops the compatibility wrapper for mmap() that allowed
this configuration to work. Too bad, I liked this, but it’s pointless to
carry now.

The development documentation is also updated to refer to NDK r16.

mini_chromium is updated to 88e056258a01450b07414642fa5fb98493c1f6ce.

d25b0242c6 gn: Fix a couple of things after 9465fc72ad90 and 2bb56fafe3bd
When I redid the Crashpad GN build a few weeks ago
(https://chromium-review.googlesource.com/c/chromium/src/+/751403), I
tried to order things according to the GN style guide
(https://chromium.googlesource.com/chromium/src/tools/gn/+/HEAD/docs/style_guide.md).
As for conditionals, I tried to stick to doing a set of conditionals
after “sources” for just “sources”, and then another one at the bottom
for everything else.

It turns out that this was a good idea because it’s an error to say
“deps += [something]” inside a conditional until you’ve already said
“deps = [something_else]” first. (Maybe that’s why I did it.)
9465fc72ad90 regressed this.

2bb56fafe3bd also left behind a couple of straggler paths that were
absolute to Chromium’s root but should have been made relative.

This also fixes a comment (about something that won’t yet work outside
of Chromium anyway, but still…)

  can be used on Fuchsia.
- Introduces GN argument "crashpad_in_chromium" which defaults to
  false. Used to set CRASHPAD_IN_CHROMIUM define, determine which
  zlib path to use, and how to package the test targets into
  binaries (one big one in Chromium, separate in Crashpad).

ef3ce94fbf Python 3 support for Python scripts (without compromising Python 2)
It’s better to be prepared for the future than…to not be.

This is mostly the result of running 2to3 on all .py files, with some
small shims to maintain compatibility with Python 2.
http_transport_test_server.py was slightly more involved, requiring many
objects to change from “str” to “bytes”.

The #! lines and invokers still haven’t changed, so these scripts will
still normally be interpreted by Python 2.

5e16410ad4 fuchsia: Download the toolchain to distinct directories per build host
I like to share a single Crashpad checkout between my non-virtual
machine and some virtual machines. Downloaded toolchains, which vary by
build host configuration, must go in paths named for the build host.
(Chromium doesn’t do this, and it bugs me.)

Rather than downloading the Fuchsia toolchain to
third_party/fuchsia/clang, this puts it in
third_party/fuchsia/clang/{mac,linux}-amd64.

The Fuchsia SDK is only published on cipd for linux-amd64, but the
sysroot that it contains ought to be perfectly functional on any
suitably-equipped build host, so this also checks out that package
unconditionally.

2bb56fafe3 Rework GN files to start to support building standalone, and also in Chromium
- Adds a .gn and a build/BUILDCONFIG.gn that uses mini_chromium's
  build/BUILD.gn.
- Adds some stub BUILD.gn files in locations where Chromium expects them
  (in //build, //testing, //third_party) containing empty targets/configs.
  These are no-ops in standalone builds, but add functionality when
  building in Chromium.  This is in preference to having a global bool
  that conditionally does Chromium-y things in the Crashpad build files.
  These stub files are all contained in a secondary source root in
  build/chromium_compatibility, referred to by //.gn.
- Adds //base/BUILD.gn which forwards to mini_chromium/base. This is
  only used when building standalone so that both Chromium and Crashpad
  can refer to it as "//base".
- Changes references to other Crashpad targets to be relatively
  specified so that they work when the root of the project is //, and also
  when it's //third_party/crashpad/crashpad as it is in Chromium.
- Moves any error-causing Mac/Win-specific files into explicit if (is_mac)
  or if (is_win) blocks as part of removing the dependency on
  set_sources_assignment_filter().

As yet unresolved:
- CRASHPAD_IN_CHROMIUM needs to be removed when standalone; to be tackled
  in a follow up.
- Not sure what to do with zlib yet, the build file currently assumes
  "in Chromium" too, and similarly having Crashpad //third_party/zlib:zlib
  pointing at itself doesn't work.

af28b83eb7 In Annotation::SetSize, use AnnotationList::Register rather than Get.
In Chromium, the AnnotationList is registered in the main executable
module. However, when using the component build, the individual shared
libraries do not explicitly initialize the CrashpadInfo nor
AnnotationList. This causes annotations to NULL-dereference the
uninitialized AnnotationList when using the component build.

By using the Register method instead, the AnnotationList will be lazily
created. In Chromium's static/release build, the AnnotationList will
still be initialized deterministically during startup.

4ee20f5831 Add Fuchsia clang and sdk to DEPS
These use CIPD (from depot_tools) to download packages created by the
Fuchsia team. The .ensure file is passed to `cipd` which currently
include specificiations for the Fuchsia team's build of clang (which,
because it's close to HEAD includes support for targeting Fuchsia), as
well as the Fuchsia SDK.

Both packages are specified as "latest" rather than pinning to a
specific revision. At this early point in the process we don't have any
good reason to pin, but that can be accomplished later by replacing that
with a specific package's SHA1.

Due to the (relatively new) 'condition': 'checkout_fuchsia', this DEPS
step will only be run when .gclient includes 'fuchsia' in the target_os
block at the top_level, e.g.

$ cat .gclient
solutions = [
  { ...  },
]
target_os = ['fuchsia']

gtest death tests, and others arrange for intentional crashes to test
Crashpad’s own crash-catching logic. On macOS, all of the gtest death
tests and some of the other intentional crashes were being logged by
ReportCrash, the system’s crash reporter. Since these reports
corresponded to intentional crashes, they were never useful, and served
only to clutter ~/Library/Logs/DiagnosticReports.

Since Crashpad is adept at handling exceptions on its own, this
introduces the “exception swallowing server”,
crashpad_exception_swallower, which is a Mach exception server that
implements a no-op exception handler routine for all exceptions
received. The exception swallowing server is established as the task
handler for EXC_CRASH and EXC_CORPSE_NOTIFY exceptions during gtest
death tests invoked by {ASSERT,EXPECT}_DEATH_{CHECK,CRASH}, and for all
child processes invoked by the Multiprocess test infrastructure. The
exception swallowing server is not in effect at other times, so
unexpected crashes in test code can still be handled by ReportCrash or
another crash reporter.

With this change in place, no new reports are generated in the
user-level ~/Library/Logs/DiagnosticReports or the system’s
/Library/Logs/DiagnosticReports during a run of Crashpad’s full test
suite on macOS.

d5ead4d70f Upstream lightly modified Chromium BUILD.gn files
Unreferenced, and not working at all in Crashpad-standalone.

Copied from Chromium at 52a9831d81f2099ef9f50fcdaca5853019262c35 to have
a point where a roll back into Chromium should be a no-op (with Chromium's
build/secondary/third_party/crashpad/... removed).

I'm not sure what we want to do about the various gni references into
Chromium (e.g. //build/config/sanitizers/sanitizers.gni, //testing/test.gni,
etc.) but I guess the sooner they live in Crashpad rather than in Chromium
the sooner we can figure out the sort of knobs and dials we need.

d7798a4e28 Tolerate safe size mismatches in the CrashpadInfo struct
The handler will now be less strict about checking CrashpadInfo struct
sizes. Assuming the signature and version fields match:

 - If the handler sees a struct smaller than it’s expecting, the module
   was likely built with an earlier version of the client library, and
   it’s safe to treat the unknown fields as though they were zero or
   other suitable default values.
 - If the handler sees a struct larger than it’s expecting, the module
   was likely built with a later version of the client library. In that
   case, actions desired by the client will not be performed, but this
   is not otherwise an error condition.

The CrashpadInfo struct must always be at least large enough to contain
at least the size field. The signature and version fields are always
checked.

The section size must be at least as large as the size carried within
the struct. To account for possible section padding, strict equality is
not required.

22e8c33b21 linux: Provide PTRACE_GET_THREAD_AREA for 32-bit x86 with glibc
glibc’s own <sys/ptrace.h> should provide this but doesn’t. See
https://sourceware.org/bugzilla/show_bug.cgi?id=22433.

The copy in compat provided it when targeting x86-64 and using glibc.
util/linux/ptracer.cc uses it when targeting both 32-bit x86 and x86-64,
so the compat definition must be made to apply to 32-bit x86 too.

This also provides a #define using the same name as the constant, which
is what glibc’s <sys/ptrace.h> does for other constants.

0e3c38a4ca win: Make ProcessSnapshotTest.CrashpadInfoChild use a loaded module
When this test examines a module that doesn’t have a CodeView PDB link,
it will fail. Such a link may be missing when linking with Lexan
ld-link.exe without /DEBUG. The test had been examining the executable
as its module. Since it’s easier to provide a single small module linked
with /DEBUG than it is to require that the test executable always be
linked with /DEBUG, the test is revised to always load a module and
operate on it. The module used is the existing
crashpad_snapshot_test_image_reader_module.dll. It was chosen because
it’s also used by PEImageReader.DebugDirectory, which also requires a
CodeView PDB link.

It’s the build system’s responsibility to ensure that
crashpad_snapshot_test_image_reader_module.dll is linked appropriately.
Crashpad’s own GYP-based build always links with /DEBUG. Chrome’s
GN-based Crashpad build will require additional attention at
symbol_level = 0.

d3b7463c7a win: Recognize nsi.dll presenting as VFT_DRV/VFT2_DRV_NETWORK
This was previously proposed at
https://chromium-review.googlesource.com/c/crashpad/crashpad/+/339103/2/util/win/pe_image_reader_test.cc#84.
It didn’t land because the change was abandoned for other reasons, but
the fix was valid. nsi.dll is not VFT_APP or VFT_DLL, and if it’s
loaded, crashpad_snapshot_test PEImageReader.VSFixedFileInfo_AllModules
fails.

Although I can’t reproduce nsi.dll being loaded spontaneously in local
testing or on trybots, it occurred in the monolithic crashpad_tests at
https://build.chromium.org/p/chromium.win/builders/Win7%20Tests%20%28dbg%29%281%29/builds/64492:

[ RUN      ] PEImageReader.VSFixedFileInfo_AllModules
