c9bcbe202d Fundamentally rewrite much of the audio DSP.
Creates a standard buffer passing, local data passing and messaging
system for processing stages. Stages can be moved to their own source
files to reduce clutter and ease assimilation of new ones. dsp.c
becomes dsp_core.c which supports an engine and framework for effects.

Formats and change notifications are passed along with the buffer so
that they arrive at the correct time at each stage in the chain
regardless of the internal delays of a particular one.

Removes restrictions on the number of samples that can be processed at
a time and it pays attention to destination buffer size restrictions
without having to limit input count, which also allows pcmbuf to
remain fuller and safely set its own buffer limits as it sees fit.
There is no longer a need to query input/output counts given a certain
number of input samples; just give it the sizes of the source and
destination buffers.

Works in harmony with stages that are not deterministic in terms of
sample input/output ratio (like both resamplers but most notably
the timestretch). As a result it fixes quirks with timestretch hanging
up with certain settings and it now operates properly throughout its
full settings range.

4fbbbf1360 Make %LC and %LR always have predictable and usable values.
%LC is now 1 for non-tiled list items (instead of undefined)
%LC and %LR are now -1 in non-list contexts.

b5cd5ce8a1 Add %LR and %LC to get at the current row and columm in skinned lists.
This allows list items to be rendered differently depending on their
on-screen position, allowing things like gradients or nonlinear alignment

680c6fcde1 Store listitem_viewport_cfg->label as skinoffset instead of raw pointer
This fixes the case where some blocks got relocated and the skin render
code couldn't find the matching viewports any more.

46285e7c2f Fix a nullpointer dereference in skinned lists.
Unfortunately this doesn't seem to be the only problem with skinned
lists. Fixing this still doesn't make them work right.

9e07ef2b0a Use buflib for all skin engine allocations.
Massive thanks to Michael Chicoine and other testers for finding the early bugs.

This removes all skin memory limitations

28d5f2aa57 Add "%LN" tag to retrieve the list item number of the current item. This allows e.g. putting item numbers in skinned lists.

3d0317a273 Rework how the skin gets the list item text to save some ram. Also allow the %LI and %LT tags to take 2 optional parameters to get a different items text/icon:
%LT(offset, nowrap) - get the text for the "being drawn"+offset item (offset being + or -). if the second param is "nowrap" (Without quotes) the text will be blank if the item would need to wrap. Same for the icon
e.g:
%LT(-1)
%LT <<
%LT(1, nowrap)

will display:
Four
Five <<
Six (or nothing if Five is the last item)
