WL#3064 - waiting threads - wait-for graph and deadlock detection

client/mysqltest.c:
  compiler warnings
configure.in:
  remove old tests for unused programs
  disable the use of gcc built-ins if smp assembler atomics were selected explictily.
  add waiting_threads.o to THREAD_LOBJECTS
include/lf.h:
  replace the end-of-stack pointer with the pointer to the end-of-stack pointer.
  the latter could be stored in THD (mysys_vars) and updated in pool-of-threads
  scheduler.
  constructor/destructor in lf-alloc
include/my_pthread.h:
  shuffle set_timespec/set_timespec_nsec macros a bit to be able to fill
  several timeout structures with only one my_getsystime() call
include/waiting_threads.h:
  waiting threads - wait-for graph and deadlock detection
mysys/Makefile.am:
  add waiting_threads.c
mysys/lf_alloc-pin.c:
  replace the end-of-stack pointer with the pointer to the end-of-stack pointer.
  the latter could be stored in THD (mysys_vars) and updated in pool-of-threads
  scheduler.
  constructor/destructor in lf-alloc
mysys/lf_hash.c:
  constructor/destructor in lf-alloc
mysys/my_thr_init.c:
  remember end-of-stack pointer in the mysys_var
mysys/waiting_threads.c:
  waiting threads - wait-for graph and deadlock detection
storage/maria/ha_maria.cc:
  replace the end-of-stack pointer with the pointer to the end-of-stack pointer.
  the latter could be stored in THD (mysys_vars) and updated in pool-of-threads
  scheduler.
storage/maria/ma_commit.c:
  replace the end-of-stack pointer with the pointer to the end-of-stack pointer.
  the latter could be stored in THD (mysys_vars) and updated in pool-of-threads
  scheduler.
storage/maria/trnman.c:
  replace the end-of-stack pointer with the pointer to the end-of-stack pointer.
  the latter could be stored in THD (mysys_vars) and updated in pool-of-threads
  scheduler.
storage/maria/trnman_public.h:
  replace the end-of-stack pointer with the pointer to the end-of-stack pointer.
  the latter could be stored in THD (mysys_vars) and updated in pool-of-threads
  scheduler.
storage/maria/unittest/trnman-t.c:
  replace the end-of-stack pointer with the pointer to the end-of-stack pointer.
  the latter could be stored in THD (mysys_vars) and updated in pool-of-threads
  scheduler.
unittest/mysys/Makefile.am:
  add waiting_threads-t
unittest/mysys/lf-t.c:
  factor out the common code for multi-threaded stress unit tests
  move lf tests to a separate file
unittest/mysys/my_atomic-t.c:
  factor out the common code for multi-threaded stress unit tests
  move lf tests to a separate file
unittest/mysys/thr_template.c:
  factor out the common code for multi-threaded stress unit tests
unittest/mysys/waiting_threads-t.c:
  wt tests
