re-work original osmo-bts with support for sysmocom femtobts

This code re-works osmo-bts to add support for the upcoming sysmocom BTS.

It also tries to add some level of abstraction between the generic
part of a BTS (A-bis, RSL, OML, data structures, paging scheduling,
BCCH/AGCH scheduling, etc.) and the actual hardware-specific bits.

The hardware-specific bits are currently only implemented for the sysmocom
femtobts, but should be (re-)added for osmocom-bb, as well as a virtual
BTS for simulation purpose later.

The sysmocom bts specific parts require hardware-specific header files
which are (at least currently) not publicly distributed.
