UBI: make gluebi a separate module

Browse Source 
[Artem: re-worked the patch: made it release resources when the
module is unloaded, made it do module referencing, made it really
independent on UBI, tested it with the UBI test-suite which can
be found in ubi-2.6.git/tests/ubi-tests, re-named most of the
funcs/variables to get rid of the "ubi" word and make names
consistent.]

This option enables MTD devices emulation on top of UBI volumes: for
each UBI volumes an MTD device is created, and all I/O to this MTD
device is redirected to the UBI volume. This is handy to make
MTD-oriented software (like JFFS2) work on top of UBI. Do not enable
this if no legacy software will be used.
This option enables gluebi - an additional driver which emulates MTD
