Enable Systrace to be used during boot.
- Add BootAgent, which is an AtraceAgent specializing in tracing
the boot sequence, and its test.
- Add --boot option. This sets persist.debug.atrace.boottrace
property, which triggers atrace during boot, writes categories
to /data/local/tmp/boottracecategories, which is used by atrace
as enabled categories, and reboots the device. Once the device
has booted up, the report is created by the user hitting
Ctrl+C.
