FSF addresses used in PA sources are no longer valid and rpmlint
generates numerous warnings during packaging because of this.
This patch changes all FSF addresses to FSF web page according to
the GPL how-to: https://www.gnu.org/licenses/gpl-howto.en.html
Done automatically by sed-ing through sources.
The function will be used in pa_sink_input_new() and
pa_source_output_new() to convert the sample spec given by the client
to a format info object. The set_format, set_rate and set_channels
will be set according to the stream flags (PA_SINK_INPUT_FIX_FORMAT
etc.).
The function will be used in pa_sink_input_new() and
pa_source_output_new(). The fallback parameters are used to merge the
data in the format info with the sink/source sample spec and channel
map, when the format info is lacking some information.
This also fixes an issue in pa_format_info_to_sample_spec(): it did
no validation for the channels value. Now the validation is taken care
of in pa_format_info_get_channels().
This also fixes an issue in pa_format_info_to_sample_spec(): it did
no validation for the rate value. Now the validation is taken care of
in pa_format_info_get_rate().
I will need to use the function from outside libpulse.
I added the channel map argument, because the function will be called
from another function that is expected to initialize the channel map.
I don't know if it's in practice necessary, but it shouldn't do any
harm either.
