read also [mariadb_safe] section.
modify the manpage accordingly (and remove a netware-specific option from it)

MDEV-5035 debian package conflict libmariadbclient18 5.5.33+maria-1~wheezy vs. mariadb-server-5.3 5.3.12-mariadb122~wheezy

Don't fail when an frm is inconsistent (legacy DB_TYPE_xxx code doesn't match the
engine name), use the engine name, ignore the legacy code.

don't set TABLE_SHARE::keys before TABLE_SHARE::key_info is set,
otherwise an error might leave only the first property set and it will
confuse TABLE_SHARE::destroy()

  Alexander Barkov 2013-09-16 backport from 10.0

mtr can crash occasionally.
This happens when mtr sends to a child mtr process (or vice-versa) a packet,

Then the other side cannot deserialize it and fails as above.
