PR 13128: Rework of commit f2013cc91ea1dba576661d6b746ee28658c8bc51 (ported)
Based on peer feedback:
- Compare privilege credentials as sets, not levels.
- Send privilege credentials as a ctl message at startup.
- Send startup ctl messages (tzinfo, relocations, privilege_credentials)
on the same control channel. Ensure channel is closed properly on error.

Author: David Smith <dsmith@redhat.com>

More PR13083 fixes to avoid sleeping in the task_finder (ported).
* runtime/task_finder2.c (__stp_get_mm_path): Call down_read_trylock()
instead of down_read() to avoid the possibility of sleeping.

Fixed PR13083 by no longer calling mmput() when possible (ported).
* runtime/task_finder2.c (__stp_utrace_attach): Don't call
get_task_mm()/mmput(). Since we're in the context of that task, the mm
should stick around (and mmput() can sleep).

Handles kernels where CONFIG_UTRACE isn't defined.

Semi-working task_finder.
* runtime/stp_utrace.c: Major revision. Uses kprobe for exec, since there
is no exec tracepoint.
* runtime/stp_utrace.h: Updated.
* runtime/task_finder2.c: Updated. Exec kprobe handler causing problems,
since a kprobe handler can't take a lock, allocate memory, etc.

Removed global utrace handler support.

global utrace handler, attach one to every interesting thread.
