Scheduling group cleanup
The C++ API for scheduling groups is going away, so use the C API.
Renumber THREAD_GROUP_* constants to have the same values as SP_*.
They are @hide so this should be OK.
The old THREAD_GROUP_FG_BOOST constant is removed, and replaced by a
(private) THREAD_GROUP_FOREGROUND constant that is just a placeholder
to correspond to SP_FOREGROUND. It is not usable at this level.
Improved performance of android_os_Process_setProcessGroup:
avoid unnecessary syscall to getpriority for each tid.
Fixed error handling in android_os_Process_setThreadGroup.
It raises an exception if set_sched_policy() returns an error.
Add comments and fix typos in existing comments.
