Break the main README into into multiple pages in the doc/ directory,
except for the tests, swig and webp_js docs which are in the corresponding
directories.
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

Change-Id: Iae875b6ec3084157837cc774c94088ca72e8dd91
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.
