BUG#24687 func_misc test fails on win64

Browse Source 
- Use same precision (milliseconds) for all time functions
   used  when calculating time for pthread_cond_timedwait
 - Use 'GetSystemTimeAsFileTime' for both start and curr time


include/config-win.h:
  Move all defines for 'pthread_cond_timedwait' to my_pthread.h
include/my_global.h:
  Move all defines for 'pthread_cond_timedwait' to my_pthread.h
include/my_pthread.h:
  Redefine "struct timespec" to better suite the needs 
  of 'pthread_cond_timedwait' for windows implementation
  Add windows specific define for set_timespec_nsec
  Move all defines related to pthread_cond_timed wait to same file
  Declare union for reading FILETIME as __int64 with correct alignment
mysys/my_wincond.c:
  Use 'GetSystemTimeAsFileTime()' both for getting start and current time
  Use new members of "struct timespec"
  Make sure the calculated timeout value never exceeds the value
  passed to set_timespec/set_timespec_nsec
server-tools/instance-manager/guardian.cc:
  Use set_timespec macro
server-tools/instance-manager/instance.cc:
  Use set_timespec macro
