Move process initialization, mlockall() and sched_setscheduler() to
only occur if initialization succeeds and is enabled. This
conserves mlock'd memory and a FIFO processing slot if (deprecated)
kernel lowmemorykiller is active.
Cleanup: Android coding standard compliance.

lmkd_unit_test gets an selinux violation when run unprivileged:
lmkd_unit_test: type=1400 audit(0.0:???): avc: denied { search } for
name="lowmemorykiller" dev="sysfs" ino=??? scontext=u:r:shell:s0
tcontext=u:object_r:sysfs_lowmemorykiller:s0 tclass=dir
permissive=0
resulting in log noise. Check for INKERNEL_MINFREE_PATH existence
after known to be escalated as root user to suppress noise.
Test: lmkd_unit_test as unprivileged user, there should be no audits.

adb: try harder to fill our test sockets.
adb: don't set has_write_error on success.
adb: move ownership of the fdevent thread into FdeventTest.
adb: guarantee that fdevent_run_on_main_thread happens last.

(cherry picked from commit 88de5556ec)
On platforms that implement sockets via underlying sockets (e.g. Wine),
a socket can appear to be full, and then become available for writes
again without read being called on the other end. Add a sleep after
each write to give the underlying implementation time to flush.
This doesn't help us if the buffer size is smaller than MAX_PAYLOAD,
but at least in the case of Wine, that doesn't seem to be the case.

Previously, each of the tests was spawning the fdevent thread manually,
in order to be able to set up listeners and such before running
fdevent_loop. Now that we have a way to run arbitrary code on the
fdevent thread, switch to having a generic fdevent thread and running
setup code via fdevent_run_on_main_thread.

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.

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.
Bug: http://b/63143027
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.
