49b50d8e97 clean up consequences of using IO/Port/Buffer for LTC output, and in related work, move calls to Session::ltc_tx_send_time_code_for_cycle() into Session::no_roll() to cover most cases where we "do not roll"

625ee55df0 don't do a pending save if slave is syncing. 
13:00 < rgareus> When a slave does initial sync, it sets speed=0, pos=XXX (required by session_process.cc state-machine to init)
13:01 < rgareus> This triggers a locate(roll=false) which in turn triggers a realtime_stop() which in turn triggers a non_realtime_stop().
[..]
13:06 < rgareus> las: the problem I have with non_realtime_stop() is that it does save a pending state IFF  get_record_enabled() is true.
13:06 < rgareus> The save can take ages (seconds), which will void the initial sync of the slave.
13:07 < rgareus> The slave enters a live-lock: sync, save, re-sync, save...
13:07 < las> rgareus: understood
13:07 < rgareus> las: I propose to workaround this: only save pending state if there is no slave or the slave is not locked.
13:07 < las> rgareus: another reason why recording + slave == bad idea :(
13:07 < las> rgareus: but yes, that sounds fine to me
13:07 < rgareus> AFICT this is not harmful. It only affects pre-record settings.
13:07 < rgareus> 'did_record' is used to save a full state after each recording.
