Fix to check library in use during runtime. Fix for Bug#16995, "idle connections not being killed due to timeout when NPTL is used". BUILD/SETUP.sh: To avoid warnings during compilation. configure.in: Fixed configure so that it can correctly detect between NPTL and Linuxthreads. include/my_global.h: Fix for Linuxthreads. include/my_pthread.h: Added defines for different libraries that can be detected. Currently only 'other', 'nptl', and 'lt' (linuxthreads) are being used. changed sigset() and signal() to my_sigset() and my_signal() include/thr_alarm.h: Removed defines for Linuxthreads. This is now detected during runtime and handled in the thr_alarm.c mysys/my_pthread.c: Runtime check for library. mysys/thr_alarm.c: Runtime checks for library and corresponding signals. sql/mysqld.cc: Added function for detecting thread library in use during start-up. THR_KILL_SIGNAL removed, setting signals during runtime.
