Most significantly, this includes:
6a848b1a1643 Require a minimum of TLS 1.2 (#1889)
Although Crashpad only uses cpp-httplib in tests, there’s no reason to
taunt fate with this tempting juicy morsel. TLS 1.1 is deprecated
(https://datatracker.ietf.org/doc/html/rfc8996, 2021-03).
This includes a change to util/net/http_transport_test_server.cc to
ensure that the test server, which runs in a child process, continues to
return the full multipart request body as it had in the past. Since
cpp-httplib 7e420aeed361 introduced multipart handling, the raw
multipart wrapper no longer appears in Request::body, but is instead
made available at Request::files. With this change, the test server will
reconstitute the original request body to match the test’s expectations.
Note that this isn’t the only way to serialize the request to be
conveyed back to the test, but it’s the most expedient because it’s what
the test already expects, and because the existing framing already takes
the form of the raw HTTP request.

Previously, ScopedSpinGuard used std::atomic::compare_exchange_weak()
in a loop to implement a spinlock. After looping for the specified
number of nanoseconds, it would give up and return an error.
A few bugs have come in on ARM platforms (https://crbug.com/340980960,
http://b/296082201) which indicate that this can fail even in
single-threaded cases where nothing else has the spinlock.
From https://cbloomrants.blogspot.com/2011/07/07-14-11-compareexchangestrong-vs.html :
> compare_exchange_weak exists for LL-SC (load linked/store
> conditional) type architectures (Power, ARM, basically everything
> except x86), because on them compare_exchange_strong must be
> implemented as a loop, while compare_exchange_weak can be
> non-looping.
and:
https://en.cppreference.com/w/cpp/atomic/atomic/compare_exchange#Notes
> compare_exchange_weak is allowed to fail spuriously, that is, acts
> as if *this != expected even if they are equal. When a
> compare-and-exchange is in a loop, compare_exchange_weak will yield
> better performance on some platforms.
>
> When compare_exchange_weak would require a loop and
> compare_exchange_strong would not, compare_exchange_strong is
> preferable [...]
My conclusion is that this logic needs to use
`compare_exchange_strong` to avoid spurious failures on ARM in the
common case when there's no other thread holding the spinlock.

This CL fixes the check for the B-key being enabled. The key that shall
be used for Pointer Authentication is denoted by bits 0 (A-key) or
1 (B-key) of __ARM_FEATURE_PAC_DEFAULT. Hence, the previous way of
checking by using bits 0 and 2 does not correctly identify the B-key.

If building for chromium, honor the ios_is_app_extension gn variable

Use CRASHPAD_IS_IOS_APP_EXTENSION build guard to not compile code
that use unavailable extension when ios_is_app_extension is set. If
the variable is not set, then check at runtime whether the API can
be used or not (if the crashpad client uses the same toolchain for
the main application and its application extensions).
This is required to pass -fapplication-extension to the compiler when

This CL introduces a new crash key 'crashpad_uptime_ns' that records the
number of nanoseconds between when Crashpad was initialized and when a
snapshot is generated.
Crashpad minidumps record the MDRawMiscInfo process_create_time using a
sysctl(KERN_PROC).kp_proc.p_starttime. This time is used to display the
'uptime' of a process. However, iOS 15 and later has a feature that
'prewarms' the app to reduce the amount of time the user waits before
the app is usable. This mean crashes that may happen immediately on
startup would appear to happen minutes or hours after process creation
time.
While initial implementations of prewarming would include some parts of
main, since iOS16 prewarming is complete before main, and therefore
before Crashpad is typically initialized.
