Nick Moriarty 8915ce1525 Fix ALSA latency (causing ALSA not to block).
With arbitrarily large latency setting (unsigned int)-1, ALSA will happily
accept all the samples we want to throw at it.

Reducing to a reasonably long (but still sub-second) value of 100ms, we
cause ALSA writes to block and work properly with --tx-carrier.

Nick Moriarty ecebf013f0 Add ability to output a carrier while waiting for data
Added --tx-carrier, which continues to output a tone while a blocking source
waits for more data on stdin.

Kamal Mostafa 40f1d50cbd fsk: calc separate divergences for mark and space bits
Calculate and consider separate signal-strength divergence values for
mark and space bits, so that imbalanced (but consistent) mark/space
strengths do not drive down confidence.

Note: This change makes all existing test cases yield very slightly
higher confidence values.

Kamal Mostafa a524e38222 minimodem: fix --baudot cmdline switch
The --baudot (a.k.a. -5) command line switch didn't actually engage
the Baudot encoder/decoder, just set 5 bits per frame.

Kamal Mostafa 0140e0df12 minimodem: --tx SAME emits 16 sync-byte preamble
Emit a preamble of 16 (hardcoded) sync-bytes if --sync-byte is
specified with --tx mode.  This makes --tx SAME emit the required
preamble of 16 0xAB's automatically.  So --rx SAME now directly
decodes the output of --tx SAME without needing to manually inject
the preamble byte(s), simplifying the test case.

Thanks to Harold Giddings, for reporting the issue.
