[ladcca] Warnings with include of list.h

[Josh Green]

I'm currently the maintainer for FluidSynth (http://www.fluidsynth.org)
and I was noticing that building with ladcca 0.4 causes some warnings to
be emitted. They don't appear to be fatal, but I thought I would let you
know. Heres what they look like:

/usr/local/include/ladcca-1.0/ladcca/list.h:291: warning: inlining
failed in call to `cca_list_sort'
/usr/local/include/ladcca-1.0/ladcca/list.h:314: warning: called from
here
/usr/local/include/ladcca-1.0/ladcca/list.h:291: warning: inlining
failed in call to `cca_list_sort'
/usr/local/include/ladcca-1.0/ladcca/list.h:314: warning: called from
here

Also, I have a question about the removal of CCA_Use_Jack/Alsa
constants. Is it sufficient to just remove these? Does this break
backwards compatibility, in other words if someone has LADCCA 0.3 will
it still work with this change? Or should we now require 0.4 with
FluidSynth? Cheers.
