If we have channels and channelmap, make sure they match.
If we have only channel_map, use this to derive channels instead of
taking the default number of channels and then ending up with a
mismatch.
If we have only channels, use this to generate a channelmap from
predefined maps or just unknown channels instead of taking the default
channel map.
If neither channels or channelmap is defined, use the defaults.
This starts breaking up the giant monolith that is the pulse-server.c
code into more manageable chunks by trying to split the module code into
individual compilation units.
errno should be set to the positive errno value.
This does not cause problems except for the pulse-server where the
errno value is negated and returned as an error result.
Make a registry of modules
Assign an unique number to each module with the MODULE_FLAG bit set
so that we can also enumerate them
Implement enumerating our internally loaded modules
Implement unloading of the module using the module id
Move module-null-sink into a separate file
Use Audio/Sink if no other media.class was given, so that it works
just like the pulseaudio module
Enable linger=true in all cases.
Parse the module arguments according to the pulseaudio syntax,
not our own syntax (which requires "" around a , delimter). Fixes
audio.position=FL,FR argument.
See #527
Implement a minimal version of the LOAD_MODULE and UNLOAD_MODULE
stream commands. The only supported module for now is the null
sink.
Modules are stored on a per-client bases, so that when clients
are disconnected, the modules they loaded is removed too.
This is enough to allow GNOME Network Displays to register a sink.
