It's self contained apart from a dependency on src/webp/types.h and src/dsp/cpu.h
For now it's only set up as an internal library, not an installable one.
Webp doesn't depend on it yet, the code is only duplicated.

The webp mux doc is merged into the API doc and the tools doc.

results in code layout changes, a couple fewer instructions; some of the
smaller functions were unaffected as they were inlined, but are updated
for consistency. this mostly affects VP8Decimate(), ReconstructIntra16()
and ReconstructUV().

A WebPPicture instance is necessary to call WebPReportProgress() which
sets WebPPicture::error_code so as well use WebPEncodingSetError() to
record errors too, instead of functions returning a WebPEncodingError.
However there must be one WebPPicture instance per thread, with error
codes merged at sync time. A mutex could simplify that but it is not
the objective of this change.

When using CMake the `<prefix>/usr/share/WebP/cmake/WebPConfig.cmake` gets
used to get the names of the libraries to link against.
Since version 1.2.1 of libwebp, libwebpmux is on by default.
This causes a linker error because the linker arg should be `-lwebpmux`
instead of `-llibwebpmux`.
This is fixable by renaming `libwebpmux` to `webpmux` in a few places.
This was identified after an update to 1.2.1 of libwebp in the OpenWrt
project:
https://github.com/openwrt/packages/pull/16766
Internally in OpenWrt, this was patched here:
https://github.com/openwrt/packages/pull/16784

When transparency is present, it's not enough to just write 32bpp samples.
One need to use the full BITMAPV3INFOHEADER syntax and specify the
masks for BGRA.
see https://en.wikipedia.org/wiki/BMP_file_format#Pixel_storage
Also remove the height-flip trick and write samples bottom-to-top instead.

(cherry picked from commit 480cd51de6)
WebPPictureImportRGB() can fail on memory allocation. In this case,
jpeg_destroy_decompress() was already called, so do not go to Error.
Free metadata as an error is returned.
