This switches the default behaviour of crashpad_handler.exe to be a
/subsystem:windows app, so that normal usage won't cause a console to be
popped up. At the same time, creates a copy of crashpad_handler.exe in
the output dir named crashpad_handler.com. The .com doesn't affect
normal operation, as the way StartHandler() uses CreateProcess()
requires a real path to a file. However, when run from a command prompt,
.com are found before .exe, so editbin the .com to be to a console app,
which will be run in preference to the exe when run as just
"crashpad_handler", as one tends to do from a command prompt when
debugging. That is:
d:\src\crashpad\crashpad\out\Debug>where crashpad_handler
d:\src\crashpad\crashpad\out\Debug\crashpad_handler.com
d:\src\crashpad\crashpad\out\Debug\crashpad_handler.exe

<no output>
d:\src\crashpad\crashpad\out\Debug>crashpad_handler.com --help

We also use the .com file in test invocations so that output streams
will be visible.

When crashy_test_program's SomeCrashyFunction is inlined into
CrashyMain, cdb doesn't demangle the decorated form of an anonymous
namespace (?A0x12345678) into the expected `anonymous namespace' string.
I experienced this in Release_x64 and Release modes using MSVS 2015

In 10.12, dyld calls abort_with_payload() on fatal error from
dyld::halt(). In previous 10.12 betas, abort_with_payload() caused the
process to appear to terminate as exit(1). This was weird, so I filed
https://openradar.appspot.com/26894758. In 10.12db4 16A270f, Apple seems
to have fixed this bug. abort_with_payload() as used by dyld now causes
the process to appear to terminate as abort() as I had requested.
A Crashpad test that assures Crashpad’s ability to catch dyld crashes
needs its expectations updated with each change to a process’ apparent
termination code. It’s updated to expect SIGABRT on 10.12 or later. No
concessions are made for previous 10.12 betas or their buggy exit(1)
behavior. Nobody should be running any 10.12 beta prior to 10.12db4
16A270f now or at any point in the future.

The Mach-O reader validated segment and section file offsets by checking
that they were relative to the same base, insisting that a section’s
file offset be the same distance from a segment’s file offset as the
section’s preferred load address was from the segment’s preferred load
address. Notably, these file offsets already could not be validated
against the Mach-O image’s start because in the dyld shared cache, for
all segments other than __TEXT, these offsets were relative to the dyld
shared cache’s start.
In 10.12dp1 16A201w, file offsets for sections in the __TEXT segment are
also relative to the dyld shared cache’s start, but the file offset for
the __TEXT segment itself is relative to the Mach-O image’s start. Being
relative to different positions breaks Crashpad’s sanity check of the
module data. https://openradar.appspot.com/26864860 is filed for the use
of distinct bases in what should be related file offset fields.
While it would be possible with a bit of work to identify modules within
the dyld shared cache and adjust expectations accordingly, in reality,
these file offset values were only used to verify that the Mach-O
module.
In addition, the file offsets stored within the Mach-O file for sections
are 32-bit quantities, even in 64-bit images. It is possible to create a
large image whose section offset values have overflowed, and in these
cases, the offset value verification would also fail.
For these reasons, all file offset value validation is removed from the
Mach-O image reader.

The limit was being reset per-thread, which isn't how it was intended or
documented. Add test to confirm the limit is more-or-less respected.

Because DumpAndCrashTargetProcess() suspends the process, the thread
suspend count is one too high for all threads other than the injection
one in the thread snapshots. Compensate for this when we detect this
type of exception.

Adds a new client API which allows causing an exception in another
process. This is accomplished by injecting a thread that calls
RaiseException(). A special exception code is used that indicates to the
handler that the exception arguments contain a thread id and exception
code, which are in turn used to fabricate an exception record. This is
so that the API can allow the client to "blame" a particular thread in
the target process.
The target process must also be a registered Crashpad client, as the
normal exception mechanism is used to handle the exception.
The injection of a thread is used instead of DebugBreakProcess() which
does not cause the UnhandledExceptionFilter() to be executed.
NtCreateThreadEx() is used in lieu of CreateRemoteThread() as it allows
passing of a flag which avoids calling DllMain()s. This is necessary to
allow thread creation to succeed even when the target process is
deadlocked on the loader lock.

Add a user-configurable cap on the amount of memory that is gathered by
dereferencing thread stacks. (SyzyAsan stores a tremendously large
number of pointers on the stack, so the dumps were ending up in the ~25M
range.)
Also reduce the range around pointers somewhat.

One possible cause for this would be a register "pointing" to the edge of an
inaccessible range. Having these zero-sized ranges doesn't break the minidump,
but it causes a warning when opening in windbg.
Also drop user-supplied zero-length memory ranges for the same reason.

In debug builds, the extra memory is sometimes getting captured
(probably by a stale stack pointer), so disable this test for now to
un-red the bots. We can probably fix it by moving this one test to a
separate binary (or perhaps just removing it, I'm not sure it's that
useful anyway above and beyond the unit test.)
