[PATCH] openbsc[master]: Add MS time. offset to gsm_lchan

[Max]

Hello Jenkins Builder,

I'd like you to reexamine a change.  Please visit

    https://gerrit.osmocom.org/1699

to look at the new patch set (#3).

Add MS time. offset to gsm_lchan

Add MS TIMING OFFSET (3GPP TS 48.058 § 8.4.8) and P offset (3GPP TS
45.010 § 1.2) which can be used to compute MS TO from known TA.

This will be used by osmo-bts (see
I4dfe5c48834a083e757d5de3236a02e15a238b28) to provide MS TO as part of
RSL MEASUREMENT RESULT.
