c11d49db88 Add a mask to MinidumpCrashpadInfo to indicate valid pointer addresses.
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.

d9c1ca1216 [ios] Bring up first draft system snapshot and iOS data collector.
Gather most of the necessary information for the system snapshot.

Note that:
 - The 'capture' portion of this CL will be moved out of the snapshot
   interface and into a separate in-process dump to disk location.
 - All of the pointer dereferences need to be wrapped in vm_read.
 - The read-fast-and-dump logic in thread_snapshot may end up in a
   different file completely, but until we pick a
   serialization/deserialization method, keep it as-is.

f5f0aa4a8e fuchsia: Implementation of system snapshot
Mostly sensible implementation for x64 via cpuid. It's too early for
Fuchsia to have a version number, so nothing is reported for those
fields. ARM64 isn't implemented at all and would hit a lot of
NOTREACHED()s.

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.

952f787f4a doc: Standardize on “macOS” in comments
Use “macOS” as the generic unversioned name of the operating system in
comments. For version-specific references, use Mac OS X through 10.6, OS
X from 10.7 through 10.11, and macOS for 10.12.
