some multiplies here and there needed some extra checks
and error reporting. Even if width * height is guaranteed
to be < 2**32, we were multiplying by num_channels and
triggering a 32b overflow.
Some multiplies were not using size_t or uint64_t, additionally.

this hasn't been set since parsing of the experimental chunk was
removed.
+ cleanup IsValidExtendedFormat(). is_fragmented has caused immediate
failure since:
4e2589f demux: restore strict fragment flag check
Change-Id: If9ecfc19556297100a6d5de1ba2cffdcbdc6c8fd
This is designed for the simple use-case where one wants to decode all
frames one-by-one in order.
Also, use this API in anim_util library, which is in turn used by
anim_diff tool.

references to fragments remain, along with some superfluous checks; these
will be removed in a future commit.

only 1 of <lib>_CPPFLAGS and AM_CPPFLAGS is used, with the former
getting precedence when it's defined. configure's DEFAULT_INCLUDES is
covering what's necessary given the include paths are all source
relative.
Change-Id: I7d14076acd266b28a88a3d92bcc3d7165284d5f3
this change has the side-effect of using directory names in the
include, silencing a lint warning.

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.
Change-Id: Id59e95ac01b9340ba8c6039b0c3b65484b91c42f
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
