filter-apply: Add ability to pass parameters to a filter module

Currently passing parameters to a filter loaded by module-filter-apply is
not possible.

To enable passing parameters to a filter this patch uses an additional property
filter.apply.{MODULE_NAME}.parameters. This way, filters like virtual-surround-sink
and ladspa-sink are fully supported. For example:
paplay file.wav --property=filter.apply=ladspa-sink \
                --property=filter.apply.ladspa-sink.parameters="plugin=ladspa \
                  label=ladspa_stereo control=0"

This patch based on:
https://cgit.freedesktop.org/pulseaudio/pulseaudio/commit/?id=caabff2728d9d588664f8a0ea2f8441804c8b91a

Note for tizen:
Proplist 'filter.apply.extra.parameters' and 'filter.apply.extra.group' are removed.
Also, their names are modified as below.
1) 'filter.apply.extra.group' to 'filter.apply.{MODULE_NAME}.group'
2) 'filter.apply.extra.parameters' to 'filter.apply.{MODULE_NAME}.parameters'
For example:
paplay file1.wav --property=filter.apply=ladspa-sink \
                 --property=filter.apply.ladspa-sink.group=group1 \
                 --property=filter.apply.ladspa-sink.parameters="plugin=ladspa1 \
                   label=ladspa_stereo control=0"
paplay file2.wav --property=filter.apply=ladspa-sink \
                 --property=filter.apply.ladspa-sink.group=group2 \
                 --property=filter.apply.ladspa-sink.parameters="plugin=ladspa2 \
                   label=ladspa_stereo control=0"
