`sem_timedwait` fails to restore the value to 0 on timeout resulting in

Instead of using pointers shared between the parent/child due to fork,
explicitly builds and passes them between processes. This is
unfortunately a bit more verbose, but seems like it tests functionality
a little better, and is required to have the test work on Fuchsia.
Also renames the ...Forked to ...Child to be correct after the change

Instead of allocating test memory in the parent and then forking and
comparing against it, the child does the allocation and passes back the
region's size and address. Additionally, switch the memcmp()s to be
value-based comparisons instead because the region isn't available in
the parent.

In doing standalone bringup of Crashpad targeting Fuchsia, it seemed
tidy to keep the same literal paths to the dependencies that Chromium
needed and add stubs/forwarding to build/secondary in the Crashpad tree
as required to make those work.
However, when trying to build Crashpad in the Fuchsia tree itself, that
would require adding forwarding files to the Fuchsia tree to match the
Chromium directory structure, which would be awkward. Instead, have
explicit dependencies in the Crashpad tree that select the locations
for various dependencies.

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

- Adds a .gn and a build/BUILDCONFIG.gn that uses mini_chromium's

- 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.

Crashpad has many tests that crash intentionally. Some of these are
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.
