doc: generate man-pages also for pipewire modules
Use pandoc + some processing to convert Doxygen html output to man pages. Requires pandoc & python for building. Generates manpages: libpipewire-modules.7, libpipewire-module-*.7

DESCRIPTION
|
||||
===========
|
||||
|
||||
A PipeWire module is effectively a PipeWire client running inside
|
||||
``pipewire(1)`` which can host multiple modules. Usually modules are
|
||||
loaded when they are listed in the configuration files. For example
|
||||
the default configuration file loads several modules:
|
||||
|
||||
::
|
||||
|
||||
context.modules = [
|
||||
...
|
||||
# The native communication protocol.
|
||||
{ name = libpipewire-module-protocol-native }
|
||||
|
||||
# The profile module. Allows application to access profiler
|
||||
# and performance data. It provides an interface that is used
|
||||
# by pw-top and pw-profiler.
|
||||
{ name = libpipewire-module-profiler }
|
||||
|
||||
# Allows applications to create metadata objects. It creates
|
||||
# a factory for Metadata objects.
|
||||
{ name = libpipewire-module-metadata }
|
||||
|
||||
# Creates a factory for making devices that run in the
|
||||
# context of the PipeWire server.
|
||||
{ name = libpipewire-module-spa-device-factory }
|
||||
