Change HandleSigtermSignal() handler to report shutdown,container. Add
the new reason to bootstat. Remove log stutter as
HandlPowerctlMessage will also do a LOG(INFO) reporting
shutdown,container as reason.
Sending SIGTERM to init is to allow a host OS to ask an Android
Container instance to shutdown. The temptation is to report
shutdown,sigterm but that does not accurately describe the usage
scenario.

Primarily, this fixes a bug where a forked child of property service
uses exit() instead of _exit, which has the unintended consequences of
running the global destructors of init proper, which leads to
unintended cleanup.
Secondly, this replaces the remaining calls of exit() that really
should be LOG(FATAL).

Tombstones (especially ones with lots of VMAs) are regularly truncated.
We can at least show the number of VMAs, though, for anyone interested
in knowing whether they got close to the default 64Ki limit.

Currently when searching a mount point from a fstab, it checks whether the
mount point of an fstab entry is the prefix of a given path, and the
next char after the match is either '\0' or '/'.
However, it will always return the fstab entry with mount point
"/vendor" when searching path is "/vendor", "/vendor/abc" or "/vendor/cde"
in the following fstab. Because "/vendor" is the prefix of "/vendor/abc"
and "/vendor/cde", and the next char after the match is '/'.
/dev/block/platform/.../by-name/vendor /vendor ext4 ro wait
/dev/block/platform/.../by-name/abc /vendor/abc ext4 ro wait
/dev/block/platform/.../by-name/cde /vendor/cde ext4 ro wait
Fix this by performing an exact match when searching the mount point.

The static analyzer complains that this memory is leaked regardless of
how I try to work around it (unless we escape the memory by using a
global or something, but...). Basically, as long as there's some sort
of operation on the reinterpret_cast'ed pointer, it complains. If we
remove the bitwise negations, it doesn't. Doing so would presumably
defeat the purpose of this test, though, so add a NOLINT.

If a function crashes by jumping into unexecutable code, the old method
could not unwind through that. Add a fallback method to set the pc from
the default return address location.
In addition, add a new finished check for steps. This will provide a method
to indicate that this step is the last step. This prevents cases where
the fallback method might be triggered incorrectly.
Update the libbacktrace code to unwind using the new methodology.
Update the unwind tool to use the new unwind methodology.
Add a new option to crasher that calls through a null function.
Create a new object, Unwinder, that encapsulates the a basic unwind. For now,
libbacktrace will still use the custom code.
Added new unit tests to cover the new cases. Also add a test that
crashes calling a nullptr as a function, and then has call frames in
the signal stack.
Bug: 65842173
Test: Pass all unit tests, verify crasher dumps properly.
