Sometimes a process will have multiple shared libraries loaded
that have defined __jit_debug_descriptor. Specifically, art testing
will load libart.so and libartd.so, which would have broken unwinding
through jit'd code for art testing if libart.so winds up being found first.
In order to avoid duplicating the code for the linker to figure out
which one is live, change the algorithm to find the first non-zero
first_entry_ set in __jit_debug_descriptor.

Test: Passes unit tests.
Test: Verified this can unwind 137-cfi on arm/arm64.

Properties right now can take any format, but that makes it hard to
specify an API for these properties as Treble intends to do.
Therefore this change introduces the idea of property types, described below.
1) 'string' this is the default type and allows any property to be set.
2) 'bool' this allows only boolean values (true|false|1|0)
3) 'int' and 'uint' these allow signed and unsigned integer values
respectively.
4) 'double' this allows floating point numbers with double precision.
5) 'size' this allows for strings matching [0-9]+[gkm].
6) 'enum' this allows only a specific set of space deliminated values
to be set, e.g. 'enum allow these strings' only allows one of 'allow',
'these', or 'strings' to be set.
Bug: 70858511
Test: unit tests, test that properties are only set if their type matches

Mount the eBPF file system under /sys/fs/bpf to allow netd to pin and
retrieve persistent eBPF map object from the file system. It helps the
system to maintain a consistent eBPF data store when netd crashed and
restart. Mount the cgroupv2 module and use the root folder of it to
monitor network statistics through eBPF program attached.
Test: eBPF map object show up under /sys/fs/bpf after netd start.

Add local BM_time_clock_gettime_*, BM_time_clock_getres_* and
BM_time_time benchmarks. Relates to the bionic benchmarks of
the same names, except adds CLOCK_MONOTONIC_RAW. Added here for
developer convenience whenever updates to the liblog or logd
code base need integration testing.
ToDo: add liblog gTests that analyse the benchmark data to confirm
that the specified integrated device has vdso access to all the
pertinent clock sources. Add liblog local benchmarks and tests to
measure the device clock drift of each possible liblog clock
source to help evaluate device configuration.
Test: liblog_benchmarks --benchmark_filter=BM_time*

Remove our circa 2014 snapshot of the google benchmarking library, and
use the now very stable google-benchmark suite. Some porting effort,
and deal with some benchmarking saddle points that take too long to
sort out. Focus on minimal API changes, _odd_ new behaviors, and style.
Test: liblog_benchmarks, ensure results in about the same range

Leaving the FUSE logic intact was confusing to OEMs, who expected
that it would still work and pass CTS. Remove all the FUSE logic
and leave a comment block about why the wrapper exists.
Also use new Android.bp makefile format.

Changes:
- New JitDebug class to handle all of the jit gdb interface.
- Add unit tests for all, along with new offline test using debug data.
- Add new Memory type called MemoryOfflineParts that has multiple
MemoryOffline objects to support the offline test.
- Update the tools to use the JitDebug object.
- Modify libbacktrace to use the JitDebug, but only looking in libart.so
and libartd.so.
- Change the Format32Bits to Is32Bit since it's more accurate and I use
it in a different context where original name didn't make sense.
- Add a new function to find global variables in an elf file
(GetGlobalVariable).
- Add a new function to determine if a pc is valid for this elf (IsValidPc).
Bug: 68396769
Test: Ran new unit tests. Added new offline test that uses jit debug data.
Test: Ran art test that generates jit data and verified a crash unwinds
Test: through the jit data.

Currently init expands properties in arguments only when those
commands are run in a subcontext. This creates a hole where
properties that should not be accessible from a given subcontext of
init can be accessed when running a command in the main init
executable (for example `start`).
This change creates a callback in subcontext init that simply expands
and returns arguments back to the main init process, to ensure that
only those properties that a subcontext can access get expanded.

Currently used clang tidy does not filter the warnings caused
by macros, even if macros come from filtered headers.
This change allows projects using ALOGV to use
readability-implicit-bool-conversion without spreading //NOLINT everywhere.

If BOARD_VNDK_VERSION is not defined, ro.vndk.version will not be
set. In this case, the device, is not able to use versioned

configuration files.
