* changes:
Enable automatic libsnapshot fuzzer runs
Also log corpus when aborted through libbase.
libsnapshot_fuzzer: Fuzz MapUpdateSnapshot.
libsnapshot_fuzzer: construct valid super partition metadata.
libsnapshot_fuzzer: Fuzz CreateUpdateSnapshots
libsnapshot_fuzzer: add additional tests for more APIs
libsnapshot_fuzzer: use protobuf
libsnapshot_fuzzer: map super image
Extend androidboot.first_stage_console cmdline property to enable
skipping module load failures without stopping at a serial console. This
is useful for GKI development.
Set androidboot.first_stage_console=2 for this behavior.
Bug: 155296582
Test: verify behavior for values 0, 1, and 2

Libunwindstack would remove duplicated items and update the `prev_map`
during reparsing `/proc/self/maps`. But we leave `prev_real_map`
pointing toward a MapInfo that will be deleted soon. It will cause a
dangling pointer issue.
Add new tests to cover this dangling pointer issue.

This won't happen in practice because device size is never
zero. Hypothetically, if it is, PartitionCowCreator still
suggests that a CoW size of 8192 bytes needs to be created. In
reality, it is not necessary.

If a CHECK or LOG(FATAL) is hit, also attempt to log the current
corpus.
Test: pass

Use protobuf because it already has all the fuzzing implemenetations.
Delete fuzz_utils.
Pros:
- Fuzzing protobuf is faster; it is easy to achieve 4K exec/s
- It is more guided; protobufs are fuzzed using mutators, and mutators
should have better knowledge of the structure of the fuzz data
- No more hand-written parsing code of the fuzz data. That code in
fuzz_utils.h is deleted.
- Corpus data can be reused even after adding new fields in the protobuf
- Corpus data is human-readable and easily manually written (it is
the text format of the protobuf)
Cons:
- The "actions" are "declared" in protobuf definition and "defined" in
C++, so there's more boilerplate to write. Adding a new "Action"
requires changes in both.
Test: run libsnapshot_fuzzer

Introduce new command to allow setting task profiles from inside .rc
script. This is to replace usage of writepid when a service is trying
to join a cgroup. Usage example from a .rc file:
service surfaceflinger /system/bin/surfaceflinger
task_profiles HighPerformance
Bug: 155419956
Test: change .rc file and confirm task profile is applied

Some tests require root to be run, so we require_root to run all of
them.
Test: tests pass as root

Test: multi_connect_dgram_socket is skipped for non-root
Test: multi_connect_dgram_socket passes for root

Operations on (unsigned long) f_bsize and f_bfree are correctly handled
on 64 bit architectures, but when switching to 32 bit, the
multiplication between the two could result in an overflow, causing the
test to crash.
Fix by using a uint64_t operand, hinting the compiler to handle the
whole multiplication with 64 bit operands.
