0a8985cd20 linux,arm: support memory tagging
64-bit ARM's Top-Byte-Ignore enables features such as memory tagging.
https://www.kernel.org/doc/html/latest/arm64/tagged-address-abi.html

Android 11 will start using memory tagging on some devices.
https://source.android.com/devices/tech/debug/tagged-pointers

Crashpad needs to remove the tags from pointers before comparing to
addresses or using with system calls.

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.

d5d78c1469 [third_party] Make mini_chromium relocatable
This will accommodate moving third_party/mini_chromium around.
The default location is unchanged for now.

There are GN variables that may need to be updated when Fuchsia's source
re-organizes its layout:

* mini_chromium_source_parent : this contains a BUILD.gn with groups and
encloses the mini_chromium_source_root.  This is controlled by the
structure of the project that depends on this project.

* _mini_chromium_source_root : this is what is normally checked out from
git, the upstream source directory

* mini_chromium_import_root : points inside source_root to make GN files
accessible.

This first step breaks out case logic for "if (crashpad_is_in_fuchsia)"
even if the value is unchanged for now.  This will faciliate a smaller
change when Fuchsia re-structures third_party sources.

00491d58ee linux: Correct handling of load bias
The load bias is documented to be the difference between
the preferred and actual load address for a module, but
is declared as an unsigned number, and math using it relies
on it being a pointer-precisioned two's complement number
that might cause over- or under-flow.

ElfImageReader and DebugRendezvous both provide ways to get
the load bias for a module and are corroborated in tests.
However, the load bias computed by DebugRendezvous does
not have access to the preferred address, so there is not
enough information to determine the signedness to use with
a VMOffset.

This patch compares the load biases modulo the numeric range
for a pointer to ignore the signedness of the value.

Also update the test module to trigger a negative load bias.

640b13f3cb linux: Don't load section headers of test module
The ELF standard allows substantial flexibility in the construction of
valid ELF modules, but there are widely followed conventions. For
example, ELF modules typically contain several segments, they do load
their program headers, and they don't load their section headers.

Bionic contains a variety of checks that the modules it's loading look
typical. Beginning with Android M, Bionic refuses to load segments which
contain the entire file contents.

9a5a789123 mac: Fix MacOSVersionNumber for 10.12.0 < version < 10.13.4
In 5412beb63386, I asserted (via my code) that the kern.osproductversion
sysctl was introduced in 10.12.0, but this was utterly wrong. It’s not
available until 10.13.4. Compare 10.13.3
xnu-4570.41.2/bsd/kern/kern_sysctl.c to 10.13.4
xnu-4570.51.1/bsd/kern/kern_sysctl.c, look for osproductversion.

This fixes expectations to not require kern.osproductversion to exist
until 10.13.4.

VM-tested on 10.12.6, 10.13.3, 10.13.4, and 10.14.0.

ca88ff1edb mac-arm64: Don’t attempt to determine the CPU frequency
Apple has never exposed the CPU frequency on ARM systems. Report it as 0
on mac-arm64 without attempting to obtain it from the system (which
would log a warning in the process).

This will resolve these harmless warnings produced when Crashpad creates
a snapshot on arm64:

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).

0bc3826129 mac-arm64: Allow target_cpu = "mac_universal" to create universal builds
When building for macOS and configured with target_cpu =
"mac_universal", bi-architecture x86_64/arm64 output will be produced.

mac_universal is, so far, a “Crashpad special” that will only work with
mini_chromium and the standalone Crashpad build, and not the in-Chromium
build. It exists to support Keystone, which intends to ship as
x86_64/arm64 universal.

Includes:

Update mini_chromium to e0008f2714a76c7f2a3854fa75774427a886d6b9

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.

5412beb633 mac: Replace MacOSXMinorVersion with MacOSVersionNumber
MacOSXMinorVersion reported just the “y” value for an OS version 10.y.z.
This is no longer sufficient to identify OS versions accurately in macOS
11. A new MacOSVersionNumber function reports the full OS version as
“xxyyzz” for an OS version x.y.z. This is the same format used by
<Availability.h> __MAC_* macros since 10.10.

MacOSXVersion is also renamed to MacOSVersionComponents for
disambiguation and proper modern nomenclature.

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
   available when targeting macOS, while <AvailabilityMacros.h>
   MAC_OS_X_VERSION_* SDK/DT macros are available on all Apple platforms,
   which may be a source of confusion. (<Availability.h> __MAC_* macros
   do remain available on all Apple platforms.)

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]+)' |
          grep -v AvailabilityMacros.h)
