d41620bc75 Added initial version of audioconvert, a generic converter of integer audio/raw formats. 
Original commit message from CVS:
Added initial version of audioconvert, a generic converter of integer audio/raw formats.
It currently supports conversion of
- channels (mono/stereo only, until someone tells me how to mix other channels)
- endianness (little/bi endian)
- signedness
- width (8, 1, 24 and 32 bits)
- depth (1 - width bits)
missing:
- enough testing (I intend to write a testsuite for this, but that's pending)
- samplerate conversion
- other goodies like format conversion etc
Expect bugs when using it.

problems this should solve:
- encoding wav files on big endian machines
- goom working with mono audio files in gst-player
- Iain's soundcard (that one is a problem in itself)
- complaints about missing conversion
- too many age old, nearly unmaintained plugins (stereo2mono etc.)
Have fun.

Original commit message from CVS:
* fix to adder: don't pull on unusable pads
* fix to ladspa: get output buffers first, so we can know how many frames to
process
- this breaks inplace buffer stuff, hmm
* fix to float2int: add a bufferpool with the same nframes as the source pad's
pool -> no extra latency
