3. Remove check of time_running != 0 in cmd_stat.cpp, because
1) We no longer need the check as we no longer open event file
for each cpu for non system wide profiling.
2) The kernel has a bug that can make time_running == 0 if
a cpu is down while profiling. But the counter value is
still valid, and shouldn't be ignored.

simpleperf: fix test record_cmd.duration_option.
The test should write perf.data to a temporary file, because
the test may not have permission to write perf.data in
current directory.

simpleperf: fix record file writer.
When running `run-as [package_name] ./simpleperf record...` on device,
simpleperf doesn't have permission to create temporary file in
/data/local/tmp. So create temporary files in the same directory
as perf.data instead.

avb: Add common verified boot tools and library.
This code is originally from the Brillo project but has been adapted for
use in all of Android. It consists of a tool - avbtool - for working
with images (e.g. boot.img, system.img). See the README file for how
it's integrated into the Android build system and how to enable it.
The main job of avbtool is to create vbmeta.img which is the
top-level object for verified boot. This image is designed to go into
the vbmeta partition (or, if using A/B, the slot in question
e.g. vbmeta_a or vbmeta_b) and be of minimal size (for out-of-band
updates). The vbmeta image is cryptographically signed and contains
verification data (e.g. cryptographic digests) for verifying boot.img,
system.img, and other partitions/images.
The vbmeta image can also contain references to other partitions where
verification data is stored as well as a public key indicating who
should sign the verification data. This indirection provides
delegation, that is, it allows a 3rd party to control content on a given
partition by including the public key said 3rd party is using to sign
the data with, in vbmeta.img. By design, this authority can be easily
revoked by simply updating vbmeta.img with new descriptors for the
partition in question.
Storing signed verification data on other images - for example
boot.img and system.img - is also done with avbtool.
In addition to avbtool, a library - libavb - is provided. This library
performs all verification on the device side e.g. it starts by loading
the vbmeta partition, checks the signature, and then goes on to load
the boot partition for verification.
The libavb library is intended to be used in both boot loaders and
inside Android. It has a simple abstraction for system dependencies
(see libavb/avb_sysdeps.h) as well as operations that the boot loader
or OS is expected to implement (see libavb/avb_ops.h).
In addition to handling verified boot, libavb will in the future be
extended to handle A/B selection in a way that can be used in the
device's fastboot implementation, its boot loader, and its
boot_control HAL implementation. This will be implemented in a future
CL.

simpleperf: allow --duration option when executing child command.
Previously --duration option can't be used while executing child
command, mainly because we use `sleep XX` child command to implement
--duration option. By using libevent, the limit doesn't exist.

Avoid binary allocation and memory copy in ReadRecordsFromBuffer(),
thus reduce Record construction overhead in
EventSelectionSet::ReadMmapEventDataForFd().
Remove RecordCache used while recording. Replace it with
RecordFileWriter::SortDataSection(). For unwinding while
recording, use low watermark to make records almost sorted
