Newer minidump stream types, like MINIDUMP_THREAD_NAME_LIST, use
64-bit RVAs (which have 64-bit location descriptors) instead of 32-bit
RVAs and location descriptors.
This adds support to MinidumpWritable for the new 64-bit RVA64 and
MINIDUMP_LOCATION_DESCRIPTOR64 types.

Crashpad annotation names are currently limited to 64 bytes.
Breakpad supports up to 256 bytes, so for compatibility with existing
clients, this increases the maximum annotation name size from 64 to
256 and adds new tests to confirm the maximum name and value sizes.

IOSIntermediateDumpWriter::Close() is intended to close the FD opened
by the in-process handler.
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

Windows extended contexts must be allocated by InitializeContext2 and
may not be aligned. This means we cannot simply store a struct in
our thread snapshot object, but must instead store enough memory
and alias our struct onto this backing memory.
Note that shadow stack pointers are not yet recorded for the initial
exception - this cannot be determined using LocateXStateFeature in
the capturing process and will be added in a future CL by plumbing
through client messages when a crashed process requests a dump.
See crash/32bd2c53a252705c for an example dump with this baked into
chrome, that has passed through breakpad without breaking it. Local
testing shows this creates valid dumps when built into Chrome, but
that the referenced memory limits may need to be increased to allow
for ssp referenced memory to be included.
See "MANAGING STATE USING THE XSAVE FEATURE SET" Chapter 13 in the
Intel SDM[0]. Many of the offsets and sizes of the extended features
are provided by cpu specific values. We can access these in Windows
using the SDK, and transfer these to the saved extended context
which in turn is understandable by windbg.
Further information is available from AMD Ch. 18 "Shadow Stacks"[1].

Adds new structures and offsets for minidump extended contexts. This
information will be captured from threads in a later CL so this CL
does not yet write different dumps, except in testing.
Minidump format for extended compacted contexts has been determined by
experiment. Offsets for where to write various parts of the context
are hardcoded to 0x550 as this matches values seen in Windows. Offsets
for misc_info_5 match those seen in working minidumps that can be opened
in windbg. Our hope is that while these could change in future, CPU
and OS vendors are unlikely to change them.
See doc[0] for a discussion of these fields and offsets in the minidump.

This will be used in a later CL to shuttle shadow stack information
from capture to minidumps. For now these fields are zeroed and have
no effect on any platform.
The x64 snapshot context we use no longer directly maps to the early
CONTEXT structure used by Windows (the prelude still matches). This
may cause confusion if people use the size of a snapshot context when
they meant to use sizeof(CONTEXT).

In a future CL we will make use of InitializeContext2 which can produce
contexts of varying sizes - this makes the existing use of a union for
wow/x64 contexts no longer feasible.
The context union in process_reader_win is replaced with a (moveable,
copyable) helper struct which currently only knows how to allocate
the replaced WOW or CONTEXT sized unions.
As this field is no longer a member of the Thread struct it cannot
be passed into other functions as a reference, so instead a pointer
is used in these functions.

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.

Change the ObjExceptionProcessor to write intermediate dumps to a
temporary location until they are confirmed by the
UncaughtExceptionHandler. Because the exception preprocessor uses
heuristics to detect iOS sinkholes, it's possible for an exception to
be identified as fatal, but not actual trigger the uncaught exception
handler. If the processor detects more than one fatal exception, it will
unregister itself and indicate this in the second dump with the key
'MultipleHandledUncaughtNSException'.
This changes also consolidates and simplifies some methods in the
InProcessHandler.

Some sinkholes use objc_exception_throw instead of rethrow, which gives
the preprocessor a second, incorrect, attempt to process the
NSException. This also means if the processor misses the first sinkhole,
on the second attempt the original throwing stack will be missing.
Instead, track the original NSException and ignore any followup calls
to the ObjcExceptionPreprocessor with the same NSException.
Also creates a ExceptionPreprocessorState class to manage the complex
types. This will be used in a followup CL to finalize caught
NSExceptions using the uncaught handler.

Stop the prune thread and the upload thread when moving to the
inactive/background state. This will reduce the number of 0xdead10cc
system kills from having a file lock during iOS suspend.
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.

https://crrev.com/c/3401563 introduced logic to guard the cached
intermediate dump writer from concurrent exceptions with a first
exception wins approach. To prevent the losing exception from returning
immediately and terminating the app before the dump is written, the
losing thread sleeps indefinitely. In the case where the losing
exception is from a call to abort() and the winning exception is a Mach
exception, the process will never terminate because abort() will first
block all signals on all other threads with a sigprocmask. This prevents
the kernel from delivering the signal converted from the Mach exception
and will never terminate. This effectively deadlocks the app.
Instead, unblock all signals corresponding to all Mach exceptions
Crashpad registers for before returning KERN_FAILURE.

iOS applications may be terminated with the exception code 0xdead10cc
when holding on to file locks in the shared container during suspension.
One approach to minimize this is to request additional background
execution time to complete the locking operation (in this case the
CrashReportUpload thread and the PruneIntermediateDumpsAndCrashReports
thread).

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.

Change signal, uncaught NSExceptions and Mach exception handlers to
prevent re-entrancy with a first-exception-wins approach to prevent
concurrent exceptions from trying to use the same cached intermediate
dump writer. Uses compare-and-swap to either return early for reentrant
signals or to wait indefinitely for anything after the first fatal
exception.
Change the NSException handler generated from the Objective-C exception
preprocessor to not used the cached intermediate dump writer and
not use the same first-exception-wins logic. This is useful because the
Objective-C exception preprocessor is imperfect and may generate
intermediate dumps that are not followed by process termination.
Simplify DumpWithoutCrashing's ownership of its intermediate dump writer
to be thread safe.
Set a handler for SIGPIPE for applications that haven't already
ignored or set a handler for SIGPIPE.

Strings in minidumps are typically NUL-terminated
(https://docs.microsoft.com/en-us/windows/win32/api/minidumpapiset/ns-minidumpapiset-minidump_string).
But the CodeViewRecord types do not use MINDIUMP_STRINGs, and do not
have a separate length field for the pdb_name. Instead, the strings are
always NUL-terminated, with the length derived from the
MINIDUMP_LOCATION_DESCRIPTOR::DataSize field. The writer is correctly
NUL-terminating the debug filename, but ModuleSnapshotMinidump is
off-by-one and including the NUL-terminator.

Crashpad currently has a circular dependency: client->snapshot->client.
The dependency from snapshot -> client only exists to pull in a single
constant for Windows (CrashpadClient::kTriggeredExceptionCode), so this
change breaks the dependency by splitting the constant out into a new
file util/win/exception_codes.h.
