c576bf35ea Add Update method to CrashpadInfo
This change adds a method to update a CrashpadInfo stream.

As part of this change, AddUserDataMinidumpStream() now returns a handle
to the added stream. This handle can be passed to
UpdateUserDataMinidumpStream() if a new version of the stream needs to
be attached to the crash report.

This method is needed for e.g., allowing Chrome's System Profile to
update, as it contains some data that takes a while to collect.

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.

d7798a4e28 Tolerate safe size mismatches in the CrashpadInfo struct
The handler will now be less strict about checking CrashpadInfo struct
sizes. Assuming the signature and version fields match:

 - If the handler sees a struct smaller than it’s expecting, the module
   was likely built with an earlier version of the client library, and
   it’s safe to treat the unknown fields as though they were zero or
   other suitable default values.
 - If the handler sees a struct larger than it’s expecting, the module
   was likely built with a later version of the client library. In that
   case, actions desired by the client will not be performed, but this
   is not otherwise an error condition.

The CrashpadInfo struct must always be at least large enough to contain
at least the size field. The signature and version fields are always
checked.

The section size must be at least as large as the size carried within
the struct. To account for possible section padding, strict equality is
not required.

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.

acabe35928 doc: Fix all Doxygen warnings, cleaning up some generated documentation
This makes Doxygen’s output more actionable by setting QUIET = YES to
suppress verbose progress spew, and WARN_IF_UNDOCUMENTED = NO to prevent
warnings for undocumented classes and members from being generated. The
latter is too noisy, producing 721 warnings in the current codebase.

The remaining warnings produced by Doxygen were useful and actionable.
They fell into two categories: abuses of Doxygen’s markup syntax, and
missing (or misspelled) parameter documentation. In a small number of
cases, pass-through parameters had intentionally been left undocumented.
In these cases, they are now given blank \param descriptions. This is
not optimal, but there doesn’t appear to be any other way to tell
Doxygen to allow a single parameter to be undocumented.

Some tricky Doxygen errors were resolved by asking it to not enter
directiores that we do not provide documentation in (such as the
“on-platform” compat directories, compat/mac and compat/win, as well as
compat/non_cxx11_lib) while allowing it to enter the
“off-platform” directories that we do document (compat/non_mac and
compat/non_win).

A Doxygen run (doc/support/generate_doxygen.sh) now produces no output
at all. It would produce warnings if any were triggered.

Not directly related, but still relevant to documentation,
doc/support/generate.sh is updated to remove temporary removals of
now-extinct files and directories. doc/appengine/README is updated so
that a consistent path to “goapp” is used throughout the file.

dbfcb5d032 win: Cap indirect memory gathering
Add a user-configurable cap on the amount of memory that is gathered by
dereferencing thread stacks. (SyzyAsan stores a tremendously large
number of pointers on the stack, so the dumps were ending up in the ~25M
range.)

Also reduce the range around pointers somewhat.

6d2d31d2d1 Use base/macros.h instead of base/basictypes.h
This was done in Chromium’s local copy of Crashpad in 562827afb599. This
change is similar to that one, except more care was taken to avoid
including headers from a .cc or _test.cc when already included by the
associated .h. Rather than using <stddef.h> for size_t, Crashpad has
always used <sys/types.h>, so that’s used here as well.

This updates mini_chromium to 8a2363f486e3a0dc562a68884832d06d28d38dcc,
which removes base/basictypes.h.

ClientInfo::set_system_crash_reporter_forwarding() can be used to
disable forwarding. The first module that is found with a non-default
value in this field will dictate whether forwarding is enabled or
disabled. It is possible to enable or disable reporting with this call,
as well as reset it to default, which will allow later modules a chance
to influence the behavior.

ClientInfo::set_crashpad_handler_behavior() is also provided, which can
be used to disable Crashpad’s handling of the exception. Most users
should not call this, but should use Settings::SetUploadsEnabled()
instead.
