add silence gen to wait apps

asterisk.conf's 'transmit_silence' option existed before
this patch, but was limited to only generating silence
while recording and sending DTMF.  Now enabling the
transmit_silence option generates silence during wait
times as well.

To achieve this, ast_safe_sleep has been modified to
generate silence anytime no other generators are present
and transmit_silence is enabled.  Wait apps not using
ast_safe_sleep now generate silence when transmit_silence
is enabled as well.
