Switch to new encoding scheme for large records.
Move to the new SPLIT/SPLIT_END encoding scheme used
by simpleperf for records with oversized (more than 2^16 bytes)
payloads.

Handle additional record types in perf.data reader.
Enhance the perf.data reader in perfprofd to handle the new kernel
symbol records that simpleperf generates. In addition, add support for
handling PERF_SAMPLE_REGS_USER and PERF_SAMPLE_STACK_USER records as
well (these wind up in perf.data files if callchain profiling is
used). Perfprofd doesn't need to look at any of the data in these
records, but it does need to be able to read past them.

Perf profile collection daemon.
Collects system-wide profiles via periodic invocation of
/system/bin/perf, placing the resulting data files in a destination
directory selected via config file. Behavior of the daemon, e.g how
often to profile, duration of profiling runs, etc, can also be
controlled with config file settings.
