rather than symlink the webm/vpx terms, use the same header as libvpx to
reference in-tree files

9326a56f8d configure: remove use of AS_VAR_APPEND 
This wasn't used often and benefits were likely minimal. Dropping it
outright is a bit simpler than adding a compatibility ifdef.

provides some compatibility with older versions of autoconf.
tested with autoconf 2.59/automake 1.7/aclocal 1.7

afa3450c11 Fix the bug in ApplyPalette. 
The auto-infer logic of detecting the 'Alpha' use case
(via check '(palette[i] & 0x00ff00ffu) != 0' is failing
for this corner case image with all black pixels (rgb = 0)
and different Alpha values.

-> switch generic use-LUT detection
