Fix RegsArm::GetPcAdjustment to check for an invalid elf before trying
to read memory.
Modify the tests for this so it crashes without this change.
Also modify the GetPcAdjustment for all different architectures so
that unless the relative pc is too small, it will return the minimum
amount that should be adjusted. This is to handle cases where we still
want to adjust the pc but it's in an invalid elf. Mostly this is for
handling cases when the pc is in jit gdb debug code so that we use the
right unwind information.

Test: Passes unit tests for libbacktrace/libunwindstack.

Previously, processes started via `adb shell` have an oom_score_adj of
-1000, making them invisible to the oom killer. This makes running a
process that consumes all memory (e.g. by leaking in a loop) lead to
the entire rest of the system (including adbd, because of bad
heuristics in the kernel) being oom killed before getting to it.

Test: `adb shell cat /proc/self/oom_score_adj` with adb root

The script prints out the boot image header
contents and extracts the kernel, ramdisk,
second bootloader and recovery DTBO images.

For non-A/B devices, the recovery partition should
be self-sufficient and not depend on any other
partition. Since recovery may need access to devices
added to the DT by overlays(for eg.display), we need to
make sure that the the recovery image also contains
the information from the DTBO image.
The following fields are added to the boot image
header for this purpose:
-boot header version
-header size
-recovery dtbo size
-recovery dtbo address

The Pixel 2 system images release was a bit of a disaster because anyone
using an old version of fastboot would blindly flash too few partitions,
potentially bricking their device. This change lets us add a line to
the android-info.txt file for a device with a new partition.
Also error out sooner in such cases by checking the requirements
immediately, rather than optimistically unpacking everything first.
Switch Action over to C++ to fix memory issues.

This change lets android::base::ScopeGuard be useful in STL containers
(e.g. std::vector<android::base::ScopeGuard<std::function<void()>>>). It
also provides perfect forwarding for android::base::make_scope_guard.

In cases where there might be a crash in the unwind library itself,
we need a method to avoid skipping these frames or we won't be able
to see the actual crash.

Provide some easy kernel panic subreasons mined from last kmesg,
generates a canonical boot reason (system boot reason) that
may aid triage.
Notably report kernel_panic,hung if [khungtaskd] triggers on
a livelock condition, forms a signals on the dashboards.
Helper function getSubreason modified to optionally enable checking
for a single quote resulting in a refactoring to ease maintenance of
the termination detection in the face of single bit errors heuristics.
