11aacfadc8 basetransform: fix vmethods 
Make a default implementation of the transform_caps vmethod so that subclasses
can call into it.
Make a default implementation of transform_size.
Avoid doing something in the vmethod trampoline.

37318a8cd2 pad: remove GstPadFixateCapsFunction 
The fixate caps function was not used externally and we have vmethods in the
base classes where it is needed.
Update some docs.
simplify some fixate functions in the base classes. Also pass the untruncated
caps to the vmethod.

4f004eff38 pad: rename GstActivateMode to GstPadActivateMode 
These might be useful:
sed -i -e 's/GstActivateMode/GstPadActivateMode/g' `git grep GstActivateMode | sed -e 's/:.*//' | sort -u`
sed -i -e 's/GST_ACTIVATE_/GST_PAD_ACTIVATE_/g'    `git grep GST_ACTIVATE_   | sed -e 's/:.*//' | sort -u`

been used if 'peercaps' was present.

01172b8126 basetransform: send delayed events earlier 
Some elements (such as videorate) might push buffers early,
for instance in in transform_ip. We want events (and in particular
any NEWSEGMENT event) to be pushed before that.

This fixes transmageddon wedging on converting a file starting
with a non zero offset to Ogg.

a121713f0c basetransform: If there's no peer we still have to transform ANY caps in getcaps() 
Otherwise elements like capsfilter will return ANY caps if no
peer is present instead of the filter caps. The transform_caps()
vfunc could do transformations to the template caps that do not
result in the unmodified template caps.

d924c30f5b base: rename allocation vmethods 
Name the allocation vmethod on srcpad decide_allocation because source pads will
have to decide what allocation parameters will be used.
Name the allocation vmethod on sinkpads propose_allocation because they will
need to configure the allocation query with a proposed values for upstream.
