InnoDB: Detect the availability of the Mac OS X fsync() work-around

Browse Source 
at run-time, so that an executable compiled on Mac OS X 10.2 can
be run on Mac OS X 10.2 (without the work-around) and Mac OS X 10.3
and later with the work-aroud enabled.


innobase/include/srv0start.h:
  Mac OS X: Add srv_have_fullfsync
innobase/os/os0file.c:
  os_file_flush(): Use F_FULLFSYNC on Mac OS X 10.3, but not on 10.2
innobase/srv/srv0start.c:
  innobase_start_or_create_for_mysql(): When compiled on OS X 10.2,
  detect if the binary is running on OS X 10.3 or later, and set
  srv_have_fullfsync accordingly.
