8f7513b7c0 upsampling_neon.c: fix WEBP_SWAP_16BIT_CSP check
this is always defined by default to 0 since:
v0.6.0-158-g663a6d9d unify the ALTERNATE_CODE flag usage

previously the !defined() check would cause a mismatch between C and
assembly.

a486d800b6 EncodeAlphaInternal: clear result->bw on error
This avoids a double free should the function fail prior to
VP8BitWriterInit() and a previous trial result's buffer carried over.
Previously in ApplyFiltersAndEncode() trial.bw (with a previous
iteration's buffer) would be freed, followed by best.bw pointing to the
same buffer.

Since:
187d379d add a fallback to ALPHA_NO_COMPRESSION

In addition, check the return value of VP8BitWriterInit() in this
function.

config.options.scaled_width or config.options.scaled_height being 0
means a ratio-conservative scaling so 7361842 was not enough.

31c28db53c libwebp{,demux,mux}.pc.in: Requires -> Requires.private
The libraries don't expose the symbols in libsharpyuv / libwebp, they're
only needed when static linking.

Noted for libwebp (Requires: libsharpyuv) in:
https://crbug.com/webp/590#c5. libwebpdemux and libwebpmux had a similar
issue with libwebp.

1d58575b18 CMake: align .pc variables with autoconf
Use prefix/exec_prefix for includedir/libdir if
CMAKE_INSTALL_{LIBDIR,INCLUDEDIR} are relative and the CMake variable
alone if they're absolute.

This matches what autoconf will produce if a custom --libdir or
--includedir are used.
