c39206f699 Provide a way to iterate over a const AnnotationList
This CL implements a const iterator to allow for iteration over a const
AnnotationList. This way, the annotation list can passed as a const
reference in search only situations.

memcpy and memchr on NULL, 0 is UB due to a C language bug. Instead, use
the C++ functions, which do not have this bug.

3215ed9086 [client] Optionally support ScopedSpinGuard in Annotation
This CL optionally integrates ScopedSpinGuard (an atomic boolean) with
crashpad::Annotation.

Subclasses of Annotation can choose to integrate ScopedSpinGuard into
their Set(...) methods to ensure reads and writes are serialized.

I didn't integrate this into StringAnnotation in this CL, but it'd be
pretty trivial to do in a follow-up.

55de7bb48e [Crashpad/Annotations] Increase maximum annotation name length to 256
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.

1aa478d161 Remove DISALLOW_* macros in crashpad
This change was partially scripted and partially done manually with vim
regex + manually placing the deleted constructors.

The script change looked for destructors in the public: section of a
class, if that existed the deleted constructors would go before the
destructor.

For manual placement I looked for any constructor in the public: section
of the corresponding class. If there wasn't one, then it would ideally
have gone as the first entry except below enums, classes and typedefs.
This may not have been perfect, but is hopefully good enough. Fingers
crossed.

#include "base/macros.h" is removed from files that don't use
ignore_result, which is the only other thing defined in base/macros.h.

161bfed35a Remove/replace unnecessary includes of logging.h
If the file just needs the CHECK/CHECK_OP/NOTREACHED
macros, use the appropriate header for that instead.
Or if logging.h is not needed at all, remove it.

This is both a nice cleanup (logging.h is a big header,
and including it unnecessarily has compile-time costs),
and part of the final step towards making logging.h no
longer include check.h and the others.

94a5a72efa mac: Tests that crash intentionally shouldn’t go to ReportCrash
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.

34699d378b Create client data structures for typed Annotations.
This introduces the Annotation object, used to declare typed
annotations, and the AnnotationList object, used to reference these. The
AnnotationList is referenced by the CrashpadInfo structure. Currently
nothing reads these.

The AnnotationList implements a lock-free linked list, into which
Annotation objects are added exactly once, when they are first set.
Clearing an Annotation merely marks it internally as such, rather than
removing it from the list.
