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.

85b7d3dd6f Mac: more robust __crash_info on 13+
It looks like macOS 13 only *sometimes* puts __crash_info in
__DATA_DIRTY. Instead of splitting by version check, let's just look
in __DATA_DIRTY if we can't find it in __DATA.

10e82d5318 mac: Make crashpad build with the 12.0 SDK
The size of dyld_all_image_infos didn't change, but the last 128 bit
of `reserved` moved out of `reserved` and got names.

On 64-bit, that's straightforward -- just move two uint64s out of the
array into fields.

On 32-bit, it's fairly awkward: It's 4 of the uintptr_t `reserved`
array, which means `UIntPtr, reserved, [4]` would have to diverge
between 32-bit and 64-bit, and also shared_cache_fs_obj_id would
straddle the `end_v14` boundary. Since macOS 12.0 doesn't support
32-bit builds, just punt on this for 32-bit. (This might possibly
mean that crashpad-on-apple-watch might not compile, but that's
a build configuration that doesn't exist.)

See comment 9 and 6 on the bug.

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.

9a5a789123 mac: Fix MacOSVersionNumber for 10.12.0 < version < 10.13.4

xnu-4570.51.1/bsd/kern/kern_sysctl.c, look for osproductversion.

df12d57e97 mac: Don’t build 32-bit ProcessReaderMac support where it’s unusable
There is no possibility to run 32-bit processes on macOS 10.15 or later.
There is never any possibility to run 32-bit processes on macOS on
arm64.

This transforms ProcessReaderMac::Is64Bit into a compile-time constant
“yes” when building for a system that will never see a 32-bit process.
This is a lightweight way to get much 32-bit support code removed from
optimized compiled output, including all of process_types. In an
optimized build of crashpad_handler for arm64, this is a 3% reduction
from 569kB to 552kB (-17kB).

f8563cb862 mac-arm64: Omit the cl_kernels workaround on this platform
cl_kernels modules have appeared since OS X 10.10 as MH_BUNDLE modules
with a __TEXT segment, one section of which claims to belong to the __LD
segment. They are produced when OpenCL is asked to compile an OpenCL
kernel for the CPU, but this currently appears impossible on arm64.

The workaround is omitted as it appears to be unnecessary, but the test
still attempts to create an OpenCL kernel for the CPU. If this ever
becomes possible, and the modules are malformed, the test will fail as
an indication that the workaround must be reinstated for arm64.

bdf9471324 mac: Switch from <AvailabilityMacros.h> to <Availability.h>
The macOS 11.0 SDK, as of Xcode 12b6 12A8189n, has not updated
<AvailabilityMacros.h> with a MAC_OS_X_VERSION_11_0 or
MAC_OS_X_VERSION_10_16 constant. However, the <Availability.h> interface
has been updated to provide both __MAC_11_0 and __MAC_10_16.
<AvailabilityMacros.h>’s MAC_OS_X_VERSION_MAX_ALLOWED, which is supposed
to identify the SDK version, is broken in the 11.0 SDK in that whenever
the deployment target is set to 10.15 or earlier, the SDK will be
mis-identified through this interface as 10.15. When using the
<Availability.h> equivalent, __MAC_OS_X_VERSION_MAX_ALLOWED, the 11.0
SDK is identified as 10.16 (arguably it should be internally versioned
as 11.0, but at least this interface allows it to be detected
unambiguously.) It’s clear that the <AvailabilityMacros.h> interface
provides no meaningful support for the macOS 11.0 SDK at all, but
<Availability.h> does.

<Availability.h> was introduced in the Mac OS X 10.5 SDK, so there is no
relevant SDK version compatibility problem with this interface.

Key differences between these interfaces for the purposes used by
Crashpad:
 - <AvailabilityMacros.h> → <Availability.h>
 - MAC_OS_X_VERSION_MIN_REQUIRED (DT) → __MAC_OS_X_VERSION_MIN_REQUIRED
 - MAC_OS_X_VERSION_MAX_ALLOWED (SDK) → __MAC_OS_X_VERSION_MAX_ALLOWED
 - MAC_OS_X_VERSION_x_y → __MAC_x_y
 - <Availability.h> __MAC_OS_X_VERSION_* SDK/DT macros are only

   MAC_OS_X_VERSION_* SDK/DT macros are available on all Apple platforms,
   which may be a source of confusion. (<Availability.h> __MAC_* macros

This change was made mostly mechanically by:

sed -i '' -Ee 's/<AvailabilityMacros.h>/<Availability.h>/g' \
    $(git grep -E -l '<AvailabilityMacros.h>' |
          grep -v AvailabilityMacros.h)

sed -i '' -Ee 's/(MAC_OS_X_VERSION_(MIN_REQUIRED|MAX_ALLOWED))/__\1/g' \
    $(git grep -E -l 'MAC_OS_X_VERSION_(MIN_REQUIRED|MAX_ALLOWED)' |
          grep -v AvailabilityMacros.h)

sed -i '' -Ee 's/(MAC_OS_X_VERSION_(10_[0-9]+))/__MAC_\2/g' \
    $(git grep -E -l 'MAC_OS_X_VERSION_(10_[0-9]+)' |

498c36b82a mac arm64: Provide something more useful from SystemSnapshot::CPURevison
hw.cputype is just CPU_TYPE_ARM64, which isn’t terribly useful.
hw.cpufamily is somewhat better as it uses <mach/machine.h> CPUFAMILY_*
values, which distinguish between different CPU generations.
CPUFAMILY_ARM_VORTEX_TEMPEST identifies A12, for example. (The fun cores
are Vortex and the boring cores are Tempest.)

There aren’t any guarantees that anything works yet.

In contrast to macOS on x86, there’s no need to support 32-bit arm on

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.

032f1aecc2 Include-what-you-use related to logging.h
Add direct includes for things provided transitively by logging.h
(or by other headers including logging.h).

This is in preparation for cleaning up unnecessary includes of
logging.h in header files (so if something depends on logging.h,
it needs include it explicitly), and for when Chromium's logging.h
no longer includes check.h, check_op.h, and notreached.h.

DEPS is also updated to roll mini_chromium to ae14a14ab4 which
includes these new header files.

cea103fb7d mac: Fix ProcessTypes.DyldImagesSelf with 10.14 SDK on 10.12
The current 10.14 SDK is numbered 101404, which is greater than
MAC_OS_X_VERSION_10_14 (101400). That was causing the test to
unintentionally fall into the “unlisted SDK” branch of the #if cascade
due to testing SDK <= MAC_OS_X_VERSION_10_14. This is corrected by
testing SDK < MAC_OS_X_VERSION_10_15 instead.

2fb4e9e6a4 mac: Update the process_types version of dyld_all_image_infos for 10.15
macOS 10.15 (“Catalina”) introduces a single new field to its
dyld_all_image_infos structure, and uses structure version 16.

macOS 10.13 and 10.14 were documented in <mach-o/dyld_images.h> as using
structure version 16, but they actually use version 15. They should have
used version 16, as they do use a structure expanded from macOS 10.12,
which also uses version 15. Previously, process_types was true to the
documentation, but now that this is known to be incorrect, it’s been
revised to reflect reality. Because two variants of the version 15
structure exist, run-time OS version detection is used to disambiguate.

cc166d71f4 Use base::size where appropriate, and ArraySize elsewhere
This is a follow-up to c8a016b99d97, following the post-landing
discussion at
https://chromium-review.googlesource.com/c/crashpad/crashpad/+/1393921/5#message-2058541d8c4505d20a990ab7734cd758e437a5f7

base::size, and std::size that will eventually replace it when C++17 is
assured, does not allow the size of non-static data members to be taken
in constant expression context. The remaining uses of ArraySize are in:

minidump/minidump_exception_writer.cc (×1)
minidump/minidump_system_info_writer.cc (×2, also uses base::size)
snapshot/cpu_context.cc (×4, also uses base::size)
util/misc/arraysize_test.cc (×10, of course)

The first of these occurs when initializing a constexpr variable. All
others are in expressions used with static_assert.

Includes:
Update mini_chromium to 737433ebade4d446643c6c07daae02a67e8deccao
