In a stack overflow test from the Fuchsia tree, an intentional crash was
being induced that at the point it was reported to Crashpad resulted in
a stack pointer outside of the stack. This caused two problems:
- Crashpad attempted to capture that whole "thing" which could have been
anything, and in the failing test was a 1G guard region
- The whole wrong thing could be very large, resulting in OOM when
trying to write the minidump, which was the symptom of the bug.
Don't attempt to continue of SP isn't at least in a mapping, and don't
capture too-large regions for the stack as nothing useful can come of
that anyway.
New test added: ProcessSnapshotFuchsiaTest.InvalidStackPointer.

ProcStatReader.Threads is flaky because it relies on an internal,
imprecise measurement of boot time. The flaky test asserts that a
thread started after the main thread should have a start time >= the
main thread. The start time is returned in a timeval, with microsecond
precision, but the measurement of boot time requires two system calls
and the time between those system calls can be approximately a
microsecond. An unlucky event such as a change in system time could
make this imprecision arbitrarily bad.
This patch lets the caller of ProcStatReader.StartTime() inject the
boot time, allowing ProcStatReader to guarantee that threads have
correctly ordered time, given the same input boot time.

The current 10.14 SDK is numbered 101404, which is greater than
MAC_OS_X_VERSION_10_14 (101400). That was causing the test to
unintentionally fall into the “unlisted SDK” branch of the #if cascade
due to testing SDK <= MAC_OS_X_VERSION_10_14. This is corrected by
testing SDK < MAC_OS_X_VERSION_10_15 instead.

Since gtest 00938b2b228f, gtest has built-in first-class support for
skipping tests, which is functionally identical (at least in Crashpad’s
usage) to the home-grown support for run-time dynamically disabled tests
introduced in Crashpad 5e9ed4cb9f69.
Use the new standard pattern, and remove all vestiges of the custom
local one.
This was done previously in 79f4a3970a64, but was reverted in
bba9d0819c12 because Chromium’s test launcher did not support
GTEST_SKIP() at the time. The deficiency is on file as
https://crbug.com/912138.
While that bug was never specifically marked as “fixed” and I haven’t
found what changed in Chromium, I do now see some use of GTEST_SKIP() in
Chromium. I also prototyped this change in Chromium at
https://chromium-review.googlesource.com/c/1854691/ and found that
GTEST_SKIP() does indeed now appear to work.

macOS 10.15 (“Catalina”) introduces a single new field to its
dyld_all_image_infos structure, and uses structure version 16.
macOS 10.13 and 10.14 were documented in <mach-o/dyld_images.h> as using
structure version 16, but they actually use version 15. They should have
used version 16, as they do use a structure expanded from macOS 10.12,
which also uses version 15. Previously, process_types was true to the
documentation, but now that this is known to be incorrect, it’s been
revised to reflect reality. Because two variants of the version 15
structure exist, run-time OS version detection is used to disambiguate.

ProcessReaderFuchsia's memory_map_ Initialize() to fail, but that was
mistakenly being ignored. Later calls then fail as well.
While we're here, also check a couple other Initialize()s that were

Stack mappings can be enormous for some processes dwarfing all other
data and making the .dmp useless. It isn't useful to capture beyond the
stack pointer, so grab only from the stack base to the stack pointer.
In the default config (safestack enabled), this isn't a major problem.
However, Chromium has safestack disabled, along with a large stack size,
so dumps with many threads become very large.
