dyn TS: OS#1778 workaround: disable TCH/F on dyn TS for nitb To avoid two phones picking mismatching TCH pchans, never pick TCH/F on dynamic TS in osmo-nitb. Add gsm_network flag dyn_ts_allow_tch_f, set to true by default in gsm_network_init(). Set this flag to false in osmo-nitb's main(). See http://osmocom.org/issues/1778 Reasoning about ways to solve this: * a compile time switch doesn't work because libbsc is first compiled and then linked to both osmo-nitb and osmo-bsc. * we could test net->bsc_api == msc_bsc_api(), but I have the so-called MSC split waiting on branch sysmocom/cscn, which will result in msc_bsc_api() not being linked in the osmo-bsc binary. * have a function am_i_nitb() with different implementations in osmo-nitb and osmo-bsc, but then we'd need to add implementations to all tests and other binaries linking lchan_alloc(). * have a flag in struct bsc_api, but so far there are only function pointers there. Having a "global" flag in gsm_network allows to add a VTY command in case we decide to keep this feature (#1781), has no linking implications and is nicely explicit. Tested that osmo-bsc still picks TCH/F on dyn TS indirectly, since I have no standalone MSC available: when compiling osmo-nitb with the line that sets dyn_ts_allow_tch_f = false commented out, TCH/F is picked as described in OS#1778; and by printf-verifying that dyn_ts_allow_tch_f == true in osmo-bsc main(), only osmo-nitb should have TCH/F disabled.
