Description
while bringing up an InSite while using libosmo-abis with --enable-sanitize, I get:
subchan_demux.c:45:17: runtime error: index 320 out of bounds for type 'ubit_t [320]'
Not a major issue, particularly as the subchan_demux is not going to be used with omso-bsc/osmo-mgw (we have a new i460 mux implementation for that).

the problem is that
- the buffer is 320 bytes (one bit per byte)
- we always append two bits (from each 64k-byte)
- only after having appended two bits, we try to achieve sync and then check if the buffer size has been reached
We could simply enlarge the buffer, but that would break ABI. Alternatively, we could check for sync/overflow after each bit.
