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
