ASIO sync issues

[Drumfix]

According to the example in the asio.h, an asio host has to
call ASIOFuture(KAsioEnableTimeCodeRead, NULL) if it wants
to receive timecode through Asio. Reaper apparently does not.

Another point: There is no need to resync anything when
syncing to ASIO timecode. Just derive the current position
from the samplevalue and samplerate. Reaper does some fancy
chasing/syncing/read ahead, which is not necessary imho.

Try this update and see if it helps:

Unfortunately the seek-ahead is still necessary as there is latency when buffering media etc.

Sync now works (with wineasio). But the displayed TC position
in qjackctl differs by an offset to the one displayed in reaper.

At 48000/64 i have to set
Syncronize by seeking ahead: 2ms
offset incoming timecode by: -5ms

to get them display the same value.

Btw another bug: "offset incoming timecode by" is not saved.

Imho when samplepos reported by the asio driver = 0 the timecode displayed in reaper should be 0.0.000 as well.
