ARM64 supports storing pointer authentication codes in the upper bits of
a pointer. This mask can be used by LLDB to mimic ptrauth_strip and
strip the pointer authentication codes. To recover an address from
pointer with an authentication code, `AND` this mask with the pointer.
If the platform does not support pointer authentication, or the range of
valid addressees for a pointer was unaccessible, this field will be 0
and should be ignored.

On iOS, holding a lock during a slow upload can lead to watchdog kills
if the app is suspended mid-upload. Instead, if the client can obtain
the lock, the database sets a lock-time file attribute and releases the
flock. The file attribute is cleared when the upload is completed. The
lock-time attribute can be used to prevent file access from other
processes, or to discard reports that likely were terminated mid-upload.

This adds a runtime exception helper (& test module) for Windows and
plumbing to allow the module to be registered by the crashpad client,
and to trigger the crashpad handler. Embedders can build their own
module to control which exceptions are passed to the handler.
See: go/chrome-windows-runtime-exception-helper for motivation.
When registered (which is the responsibility of the embedding
application), the helper is loaded by WerFault.exe when Windows
Error Reporting receives crashes that are not caught by crashpad's
normal handlers - for instance a control-flow violation when a
module is compiled with /guard:cf.
Registration:
The embedder must arrange for the full path to the helper to
be added in the appropriate Windows Error Reporting\
RuntimeExceptionHelperModules registry key.
Once an embedder's crashpad client is connected to a crashpad
handler (e.g. through SetIpcPipeName()) the embedder calls
RegisterWerModule. Internally, this registration includes handles
used to trigger the crashpad handler, an area reserved to hold an
exception and context, and structures needed by the crashpad handler.
Following a crash:
WerFault.exe handles the crash then validates and loads the helper
module. WER hands the helper module a handle to the crashing target
process and copies of the exception and context for the faulting thread.
The helper then copies out the client's registration data and
duplicates handles to the crashpad handler, then fills back the various structures in the paused client that the crashpad handler will need.
The helper then signals the crashpad handler, which collects a dump then
notifies the helper that it is done.
Support:
WerRegisterExceptionHelperModule has been availble since at least
Windows 7 but WerFault would not pass on the exceptions that crashpad
could not already handle. This changed in Windows 10 20H1 (19041),
which supports HKCU and HKLM registrations, and passes in more types of
crashes. It is harmless to register the module for earlier versions
of Windows as it simply won't be loaded by WerFault.exe.
Tests:
snapshot/win/end_to_end_test.py has been refactored slightly to
group crash generation and output validation in main() by breaking
up RunTests into smaller functions.
As the module works by being loaded in WerFault.exe it is tested
in end_to_end_test.py.

IOSIntermediateDumpWriter::Close() is intended to close the FD opened

Currently, InProcessHandler::ScopedLockedWriter::~ScopedLockedWriter() does invoke IOSIntermediateDumpWriter::Close().
However, InProcessHandler::Initialize() invokes the utility CreateWriterWithPath() which directly creates an IOSIntermediateDumpWriter. It neither uses ScopedLockedWriter nor invokes Close().
This fixes the issue by:
1) Making IOSIntermediateDumpWriter::~IOSIntermediateDumpWriter() DCHECK() that it's closed
2) Calling IOSIntermediateDumpWriter::Close() from InProcessHandler::~InProcessHandler() and from test files

Linking crashpad (//third_party/crashpad/crashpad:util) target
into a target built for a secondary toolchain could cause noop
build failure because of an incorrect `include_dirs` directive.
The library depends on a generated buildflag, which when in a
secondary toolchain is generated to $root_gen_dir, a directory
that includes the toolchain name (except for the primary one).
The target added $root_build_dir/gen to its `include_dirs`
which is equal to $root_gen_dir for the primary toolchain, but
distinct for secondary toolchain.
Moreover, `include_dirs` define directly in a `source_set` are
placed before any `include_dirs` values inherited from configs.
This means that $root_build_dir/gen was before $root_gen_dir in
the list ($root_gen_dir is inherited from default config when
building Chromium).
The result is that building any crashpad files would result in
them trying to first include the version of the buildflag that
was generated for the primary toolchain, and if not found, using
the correct one. This was then recorded in the depfile generated
by the compiler.
This meant that it was possible for the build to be incorrect
(as the content of the buildflag may be different between the
two toolchains) and cause flaky noop failures (as the buildlag
generation for the primary toolchain and the compilation of
the source file for the secondary toolchain are unordered, but
a dependency was recorded via the depfile leading ninja to
report a dirty build).
The fix is simple, use the correct value $root_gen_dir in the
`include_dirs` directive.

Stop the prune thread and the upload thread when moving to the

Wait to start the prune thread when the application is active.
Otherwise, for iOS prewarmed applications, the prune thread will
regularly start when the application is foregrounded for the first
time when the user intentionally runs the app.
It's still possible for either the prune thread or the upload thread to
have a file lock during iOS suspend, such as when a task started in the
foreground and does not complete in time for suspension. Future work
should include considering BackgroundTasks and/or NSURLSessions, which
can more safely run in the background.

Previous commits[1][2] modified tests to require looking at RawLog
output to validate the success or failure of the iOS InHandlerProcess.
Previously this would use freopen to direct the RawLog to a file.
However, freopen introduces a race where the log file may not be
associated with stderr, and instead may interfere with the
InProcessHandler's cached writer fd. This caused flake with the
intermediate dumps sometimes including stderr logging.
Since the test fixtures only needs to know about the output of RawLog,
instead add a crashpad::internal::SetFileHandleForTesting method to
that swaps out STDERR_FILENO with the test fixture's fd.

Mig-generated files contain mig identifiers, which include timestamp and mig build info.
To improve build determinism and goma cachehits we can replace these lines with something stable.

Previously we would rely on implicit re-raising to deliver signals to
the underlying handler on POSIX systems if the signal is detected as
being re-raisable via WillSignalReraiseAutonomously(). This detection
mechanism is imperfect, as it will misclassify signals delivered as
a result of kill(2) when passing a signal number usually used for
synchronous signals, but now also asynchronous MTE tag check faults,
which are delivered as SIGSEGV signals on Linux. As a result, these
signals would not be re-raised and therefore would be discarded.
Although we could, for example, teach WillSignalReraiseAutonomously()
about MTE faults, the signal would still be re-raised via raise(3)
and therefore we would lose the information in siginfo.
We can avoid discarding these signals on Linux while at the
same time preserving the siginfo by making use of the syscall
rt_tgsigqueueinfo(2) which delivers a signal together with a
user-provided siginfo. The problem still exists on non-Linux POSIX
systems because this syscall is Linux-specific.
With kernel versions prior to 3.9, the kernel will reject the
rt_tgsigqueueinfo() syscall with EPERM. If that happens, follow
the non-Linux code path.

Testing in beta has shown a few examples of a cropped intermediate dump
still providing useful information, but due to the order intermediate
dump data is written, could be improved.
- Change the order of writing data to the intermediate dump by
increasing the priority of the Exception block from:
Header / Process / System / Threads/ Modules / Exception
to
Header / Process / System / Exception / Threads / Modules
- Annotate minidump reports generated from incomplete intermediate
dumps with the key 'crashpad_intermediate_dump_incomplete'.
- Handle partial exception contexts rather than throwing them away.

This implements a per-report retry rate limit (as opposed to per upload
rate limit in ShouldRateLimitUpload). When a report upload ends in a
retry state, an in-memory only timestamp is stored with the next
possible retry time. This timestamp is a backoff from the main thread
work interval, doubling on each attemt. Because this is only stored in
memory, on restart reports in the retry state will always be tried
once, and then fall back into the next backoff. This continues until
5 retry attempts are reached.
