Added new option --sync-frm / --skip-sync-frm

Marked --bdb-no-sync as deprecated
Added --sync-bdb-logs / --disable-sync-bdb-logs as a synonym / alternative.


mysys/my_getopt.c:
  Changed my_getopt so that disabled_my_option can be used for
  GET_BOOL type options too.
sql/mysql_priv.h:
  Added opt_sync_frm
sql/mysqld.cc:
  Added sync-frm / disable-sync-frm to mysqld, to be able to disable
  use of my_sync() (fsync()). This defaults to behavior in 4.0.16
  and before, where creating of new tables is quicker than currently.
  This option is enabled by default.
  
  Marked --bdb-no-sync as deprecated option and added another one,
  --sync-bdb-logs besides. --bdb-no-sync and --disabled-sync-bdb-logs
  are now synonyms.
sql/unireg.cc:
  One can disable my_sync() by using --disable-sync-frm
