d851cd1d85 demux: make the parse a bit more strict 
* 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

627f5ca66b automake: add reference to libwebp for mux/demux 
this allows DLLs to be built under mingw and sets up a more obvious
dependency in the shared objects

068eba8d58 Demux: Add option to get frame count using GetI() 
Also tweak the code for single image and fragmented image cases, so that
dmux->num_frames_ is always correct.

df02e4ce93 WebPDemuxGetI behavior change: 
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.
