This changes the crash export mechanism in Microdroid. For this, we
create module tombstone_handler which exports methods very similar to
tombstoned.h
For Microdroid (detected using prop: ro.hardware): It calls newly
introduces microdroid specific methods to connect/notify completion of
crash.
Individual methods:
connect -> For Android, it would connect to
tombstoned which would send it the fd corresponding to newly created
file on /data/tombstone_ . For Microdroid, we connect to tombstone
server on host via vsock & populate these sockets as the output fd.
crash_dump, in the later case, would directly write on the socket(s).
notify_completion: For Microdroid, it would simply shutdown the vsock
connections.
Note when OS is not Microdroid: It calls corresponding methods of
tombstoned_client, essentially serving as a proxy.
Detailed design: go/vm-tombstone

Due to how CF is built and tested, VABC is enabled even when not
supported by the kernel. To work around this add some logic in
libsnapshot and the test harness to recognize this situation and
silently flip off the VABC flag.
This also fixes the -force_mode option to vts_libsnapshot_test, so that
it will skip tests that aren't supported by the device.

Combine two if-statements. This change is fine because:
* The code between the two if-statements does not queue actions.
* If an action is queued from another thread then WakeMainInitThread()
is called after the action has been queued.

For many years, services declaring "console" would only be started if the
console device specified by androidboot.console= was present under /dev.
However, they would also be started if the /dev/console node existed.
This fallback causes problems with newer GKI kernel images which now
hard-code "console=ttynull" via CONFIG_CMDLINE, which essentially means
/dev/console always exists, even though this console points nowhere.
It also causes problems on devices where the androidboot.console was not
the same as the kernel dmesg console ("console="), such as cuttlefish,
because those platforms could not simultaneously enable kernel logging
but disable the interactive serial console feature. The framework just
assumed both would be muxed on the same serial port. Cuttlefish had a
workaround, to use "androidboot.console=invalid" to avoid the fallback,
but this doesn't work on devices which still want to mux the kernel logs
and interactive serial console.
This change resolves the issue in a better way, by introducing a new
boolean property called "androidboot.serialconsole". Setting this to "0"
will disable the console services, regardless of whether the
/dev/console or /dev/${ro.boot.console} devices exist. Older kernels
and bootloaders don't need to set this and can rely on the old behavior
in init, but bootloaders booting newer kernels must set it to avoid the
"performance is impacted" message due to console services being started.

1. Fixes this test under clang coverage, which is run under presubmit
for TEST_MAPPING files. When we spawn under a minijail, and the
process exited normally (which is the case for recoverable), clang
coverage would use atexit handlers to dump some stuff using banned
prctl's and other syscalls. Instead of allow-listing them all which
sounds like a huge pain, call _exit() which skips those handlers.
2. Extends the invariant testing to make sure that recoverable GWP-ASan
recovers both the first time, and a second time in a different slot.
