Stop coalescing kernel processes to the same name, other changes.
* Do not coalesce kernel processes to the same name as knowing the
breakdown of kernel cycles by the name of kernel or user process is
useful.
* Make the perfprofd tests run well in 64-bit mode.
* Add debugging "-x PATH" flag to perfprofd which can be used to convert
the given perf data file to the encoded proto format and immediately
exit.
Test: 32-bit and 64-bit perfprofd_test on the device

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.

Reduce oom_score_adj to zero for perfprofd.
Up until this point perfprofd has inherited a
decreased OOM score of -1000 from init -- this
doens't make sense given that perfprofd is not
a critical system service. This fixes perfprofd to
reduce its oom_score_adj to 0.

Support for additional profile annotations.
Includes "device booting", "on charger", and cpu utilization.
Prototype version of "camera active" (not yet enabled). Also in
this patch, separate out the code to read perfprofd's config
file and place into a separate source file.

Perfprofd: various changes related to config parameters.
Details:
- turn "max unprocessed profiles" into a configurable parameter.
- use a longer default collection interval
- reread config file on very iteration through the main loop,
so as to incorporate new parameters written by the upload service

Second round of changes to 'perf' profile collection daemon.
Details:
- avoid use of system() in favor of fork/exec.
- add option to selectively disable/enable mpdecision service around perf
collection runs to improve profile quality and avoid kernel pmuevents issues.
- default to using 'simpleperf' instead of 'perf'

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.
