f4fb623aba audiodecoder: avoid unnecessary gst_pad_has_current_caps() checks

stored somewhere already.

instead of the input format.

ddfe7a2808 win32: remove outdated build cruft 
This hasn't been touched for generations, doesn't work,
and is just causing confusion. We also don't want to
maintain these files manually.

5cef3f31ad audio-converter: make a copy if we can't write in unpack 
If we don't have writable memory, make sure to make a copy of the input
samples into a temporary (writable) buffer, even if we are dealing with
a native intermediate format that we don't need to call the unpack
function for.

15df3c812b audio/videodecoder: use gst_pad_peer_query_caps to make output caps 
gst_pad_get_allowed_caps() will return NULL if the srcpad has no peer.
In that case, use gst_pad_peer_query_caps() with template caps as filter
to have negotiated output caps properly before forwarding GAP event.

761142e15a audioencoder: Add note to the documentation about various settings being reset before set_format() 
It's quite unexpected behaviour that various subclass settings are just
reset before set_format(). Unfortunately changing this now has the risk
of breaking existing code but we should reconsider this for 2.0.

ef3844cf6f audio-converter: Avoid conversion when possible

8a8b12189e audio-converter: improve processing loop

980163457e audio-convert: simplify API 
Simplify the API, we don't need the consumed and produced output
arguments. The caller needs to use the _get_in_frames/get_out_frames API
to check how much input is needed and how much output will be produced.
