Remove the debuglog stuff. ktrace is more useful now.

For PR bin/37347:

- Override __libc_thr_init() instead of using our own constructor.
- Add pthread__getenv() and use instead of getenv(). This is used before
  we are up and running and unfortunatley getenv() takes locks.

Other changes:

- Cache the spinlock vectors in pthread__st. Internal spinlock operations
  now take 1 function call instead of 3 (i386).
- Use pthread__self() internally, not pthread_self().
- Use __attribute__ ((visibility("hidden"))) in some places.
- Kill PTHREAD_MAIN_DEBUG.

- Reinitialize the absolute minimum when recycling user thread state.
  Chops another ~10% off create/join in a loop on i386.
- Disable low level debugging as this is stable. Improves benchmarks
  across the board by a small percentage. Uncontested mutex acquire
  and release in a loop becomes about 8% quicker.
- Minor cleanup.

Remove the PTHREAD_SA option. If M:N threads is reimplemented it's
better off done with a seperate library.

logging/debugging changes:
- add PTHREAD_PID_DEBUG which prints the pid before each debuglog line
- output thread returned in pthread__next
- add asserts in pthread__sched akin to asserts in pthread__sched_bulk:
  check if scheduled thread is at front/end of queue
- pthread__upcall: output event/interrupted LWP count instead of LWPid
  of the first event/interrupted LWP (since unblock upcalls can have
  multiple event LWPs).
- pthread__find_interrupted: output LWPid here

Dodge a potential race condition in pthread__debuglog_printf(). It's
still possible for multiple threads to write into the same space, but
they shouldn't be able to corrupt the write pointer in the process.

Also, check for pointer-lapping a bit more carefully in the wrap
vs. non-wrap case.

Add a mechanisim for debugging that is less likely to change scheduling
behaviour than using printf (writing to a shared memory segment), and a
simple tool for dumping the buffer. Partly inspired by the kernel msgbuf
code.
