6265674c98 Migrate to NOTREACHED()
This was tested locally by adding "-Wunreachable-code-aggressive" after
making NOTREACHED() [[noreturn]] in mini_chromium and then getting that
to compile.

6af42bc0b2 Use NOTREACHED_IN_MIGRATION()
This was generated by replacing "  NOTREACHED()" with
"  NOTREACHED_IN_MIGRATION()" and running git cl format.

This prepares for making NOTREACHED() [[noreturn]] alongside
NotReachedIsFatal migration of existing inventory.

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.

78bcb55e1c Construct ProcessMemoryLinux using PtraceConnection
Update ProcessMemoryLinux to be constructed from PtraceConnection
instead of being Initialize()d with a pid_t.

This allows consolidating PtraceClient's BrokeredMemory with
ProcessMemoryLinux and providing the PtraceConnection as a alternative
to the memory file (previously only done for brokered connections).

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.

10fd672bde linux: Enable brokered memory reading
This change:
1. Updates the broker's memory reading protocol to enable short reads.
2. Updates Ptracer to allow short reads.
3. Updates the broker to allow reading from a memory file.
4. Updates the broker's default file root to be "/proc/[pid]/".
5. Adds PtraceConnection::Memory() to produce a suitable memory reader
for a connection type.

59c5d848e5 linux: Refactor ptrace usage.
1) Add PtraceConnection which serves as the base class for specific
types of connections Crashpad uses to trace processes.
2) Add DirectPtraceConnection which is used when the handler process
has `ptrace` capabilities for the target process.
3) Move `ptrace` logic into Ptracer. This class isolates `ptrace` call
logic for use by various PtraceConnection implementations.
