manuals/OsmoNITB: integrate into this repository

Move from doc/manuals to manuals/OsmoNITB as we have two more manuals
(OsmoMGCP and OsmoNAT) that need to be moved to manuals/. Make the
manuals build without a toplevel configure.ac file from autotools:

$ cd manuals/OsmoNITB
$ make

openbsc/configure.ac is not used to integrate the manuals, as it would
be extra effort to integrate all three of the manuals there. This is
not worth it for the legacy codebase.
