there's still some malloc/free in the external example
This is an encoder API change because of the introduction
of WebPMemoryWriterClear() for symmetry reasons.
The MemoryWriter object should probably go in examples/ instead
of being in the main lib, though.
mux_types.h stil contain some inlined free()/malloc() that are
harder to remove (we need to put them in the libwebputils lib
and make sure link is ok). Left as a TODO for now.
Also: WebPDecodeRGB*() function are still returning a pointer
that needs to be free()'d. We should call WebPSafeFree() on
these, but it means exposing the whole mechanism. TODO(later).

otherwise make sure that all frames are marked as a fragment. there's
still some work to do with validation if fragments are expected to cover
the entire canvas.

Earlier "f = f->next_" was executing for both inner and outer loop, thus
skipping validation of some frames.

WebPDemuxPartial() returns NULL for both of the following cases:
- There was a parsing error.
- It doesn't have enough data to start parsing.
Now, one can differentiate between these two cases by checking the value
of 'state' returned by WebPDemuxPartial().

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

(cherry picked from commit d640614d54)
* VP8L shouldn't have an alpha chunk
* expect an animation to only contain frames, not a mix of image chunks
* enforce ANIM/ANMF order
* expect a full frame in a complete file

this allows DLLs to be built under mingw and sets up a more obvious
dependency in the shared objects

Also tweak the code for single image and fragmented image cases, so that
dmux->num_frames_ is always correct.

It now returns ALPHA_FLAG for lossless images with alpha, that don't
have a VP8X chunk.
This is consistent with similar methods WebPMuxGetFeatures() and
WebPGetFeatures().

If it's not a partial file and parser returns PARSE_NEED_MORE_DATA, then
consider it to be PARSE_ERROR.
