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

Browse Source 
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.

  Moved MY_SYNC_DIR to ensure it never clashes with ME_JUST_INFO
