Standard C++ doesn't allow implicit conversion between function
pointers and void*. MSVC does allow that, so clang-cl also allows it
but emits a -Wmicrosoft-cast warning. We want to enable this warning to
make the compiler behave more similar on different platforms, so add an
explicit cast to void*. (GetProcAddress() returns FARPROC, a function
pointer type.)

This caused an error with clang, but not msvc.
At first I thought this might be a discrepancy between the warning
levels used, but it appears msvc was okay with this because ints are

Google Test has recently switched the default death test style from
"fast" to "threadsafe". This is a better default, and Chrome will adopt
it on all platforms except for Android.
In threadsafe mode, the death test in
client/simple_string_dictionary_test.cc consistently crashes with the
wrong expectation on Mac. Fortunately, breaking the test up into two
smaller tests makes the failures go away, and also adds a bit of clarity
into what is being tested.

After the avoidance of abspath(), automatic regeneration of ninja files
was broken following a test run. The problem is that the
--runtime-deps-list-file argument gets saved into the regeneration rule,
but it's relative to the cwd. The cwd is CRASHPAD_DIR on the first run,
but the binary_dir on regenerations, so either way it doesn't work (this
should probably fixed in either GN or ninja).
We could abspath the path the runtime deps targets file to avoid this.
However, it's a bit cluttery to have that --runtime-deps-list-file in
the regeneration rule anyway, when really it's only required to extract
runtime deps at test-running time. (Also, if you happened to delete only
targets.txt from the out dir, the regeneration would mysteriously fail.)
So since generation only takes tens of milliseconds, the best thing to
do is just remove it from the regeneration rule by re-running gn gen
without the flag after we've extracted the .runtime_deps to prepare for
the run.

Pulls the concrete non-test implementations of MemorySnapshot out into a
template. They were effectively identical on Mac and Linux/Android, and
I was going to have to add another identical one for Fuchsia.
Unfortunately it needs to be a template because of the snapshot merging
template it calls that needs the platform-specific ProcessReader (so it
can't just pass in a base ProcessMemory in initialization instead).
This is used on Mac, Linux, Android, and Fuchsia, but there is still a
Windows implementation (different because its ProcessReader is a bit
different) and a test implementation.

These tests needed to be updated to expose CrashpadInfo in the same way
as the main CrashpadInfo g_crashpad_info is found on
Linux/Android/Fuchsia.
Unfortunately, while the tests pass on Fuchsia when run in isolation,
the implementation of dlclose() on Fuchsia currently does nothing. So,
if the full test suite is run, there's interference between the test
modules (i.e. the values in _small vs. the values in _large), so the
tests fail.
I filed ZX-1728 upstream about this to see if it might be implemented,
or if the test will need to spawn a clean child to do the module load
tests in.

In preference to (the reverted)
https://chromium-review.googlesource.com/c/crashpad/crashpad/+/923178
this does not share implementation with the tests in
snapshot/crashpad_info_client_options_test.cc. This is not done because
those tests use faked CrashpadInfo structures that are intentionally
differently sized than the current defintion of CrashpadInfo, meaning
that the scoped reset could overwrite past the end of the structure.
Not resetting these was causing CrashpadInfoClientOptions tests to fail
on Fuchsia, because dlclose() [legally] doesn't do anything, so
modifying the current binaries CrashpadInfo caused the expected values
from child .sos to be ignored. That could be worked around in that test
too, but it's probably better to clean up the global state in this test
anyway.
