When throttling is enabled, one voice frame will be processed every
20ms. This is useful for e.g. playback of a file as a RTP stream.
Without this option, the entire file would generate a flood of RTP
messages, rather than a continuous stream.

For a long time the RTP payload type was hard-coded for outgoing
frames. The problem is that according to RFC 3551 only GSM FR has
a static payload type value (see table 4, value 3). For other
codecs the payload type may be negotiated between the both
sides dynamically (i.e. in range 96-127).
Let's allow a binary/API user to configure this manually.

Closes: OS#2482
In order to give advanced control over a processing queue,
it would be better to have the checking function separated from
the osmo_gapk_pq_prepare(). Moreover, this change introduces an
additional 'strict' checking mode that requires a queue to have
a source item first and a sink item in the last position.
Since this change, every processing queue may optionally have
an associated human-readable name. If name is not required,
NULL should be passed to the osmo_gapk_pq_create().
Previously the osmo-gapk application used to exit as soon as all
the frames are processed, no matter has the sink finished its
internal processing (e.g. ALSA playback).
Instead of immediately shutting down the application, it is
better to try to break the processing queue first, and stop
the execution immediately if second SIGINT is received.
The printf() writes the text into stdout, which may be undesirable
in some use cases. Moreover, the printed information was redundant.
So, let's drop such calls.
Since this change, the libosmogapk uses the Osmocom logging
framework. By default, logging is disabled and could be enabled
by the external applications calling the osmo_gapk_log_init()
with a desired log target as an argument.
Since GAPK package contains a library and the representative
osmo-gapk application, the 'main.c' looks a bit confusing. Let's
use the common naming scheme.
