Added logging of all errors from my_read/my_write/my_pread/my_pwrite/my_open & my_malloc to mysqld error log if one sets log-warning to 10 or 11

The idea is that my_global_flags is ored to the MyFlags parameter for the above functions if the MY_WME flag is not set.
As the my_global_flags has ME_JUST_INFO (mark error as 'note') and possible ME_NOREFRESH (write error to log) this will force mysqld to log the not critical error to the log as a note.


 

include/my_sys.h:
  Moved MY_SYNC_DIR to ensure it never clashes with ME_JUST_INFO
  Added my_global_flags
mysql-test/Makefile.am:
  Removed not used bugs directory
mysys/my_init.c:
  Added my_global_flags, a variable that is ored to MyFlags in a those mysys functions we want extra logging.
mysys/my_malloc.c:
  Added support for my_global_flags
mysys/my_open.c:
  Added support for my_global_flags
mysys/my_pread.c:
  Added support for my_global_flags
mysys/my_read.c:
  Added support for my_global_flags
mysys/my_static.c:
  Added my_global_flags
mysys/my_write.c:
  Added support for my_global_flags
sql/mysqld.cc:
  Set my_global_flags for warning levels 10 & 11
sql/sql_base.cc:
  Don't increment unhandled errors for notes or warnings.
