This is a follow up to:
ee8e8c62 Fix member naming for VP8LHistogram
This better matches Google style and clears some clang-tidy warnings.

After:
2c70ad76 muxread,CreateInternal: fix riff size checks (cl/200674839)
`SizeWithPadding()` adds `CHUNK_HEADER_SIZE` (plus additional 1 byte
padding if needed). A later check included `CHUNK_HEADER_SIZE` before
capping the value of the size passed to `WebPMuxCreateInternal()`,
missing cases with a small amount of extra data after the RIFF chunk
(like a newline when the file is opened and saved in a text editor) and
setting size to an incorrect value, so larger sizes would also fail.
Another check of `riff_size < CHUNK_HEADER_SIZE` after the call to
`SizeWithPadding()` is removed because 1) it could not fail given
`SizeWithPadding()` adds `CHUNK_HEADER_SIZE` to the value; and 2) it is
redundant as `size < RIFF_HEADER_SIZE + CHUNK_HEADER_SIZE` is checked
earlier in the function.

This is available with clang. Clears warnings of the form:
warning: empty expression statement has no effect; remove unnecessary
';' to silence this warning [-Wextra-semi-stmt]
As a side-effect it also clear a few -Wpedantic warnings with gcc:
warning: ISO C does not allow extra ';' outside of a function
[-Wpedantic]

several calls to ChunkSetHead() were unchecked, causing the chunk to
leak should the call fail due to OOM
Tested:
for i in `seq 1 1125`; do
export MALLOC_FAIL_AT=$i
./examples/gif2webp gif_file
./examples/gif2webp -mixed gif_file

Check encoded_frames_ count and call FlushFrames if necessary after
IncreasePreviousDuration. Avoids an overflow in encoded_frames_[] with
-kmax 0 and an assertion failure related to the previous and keyframe
durations when a frame is forced in this way.

* Assert chunklist
* fix potential memory leak and
* fix null pointer access
There should not be several alpha_ or img_ chunks in SynthesizeBitstream. Use ChunkListDelete in MuxImageRelease to be safe.
A null pointer accessed in WebPMuxPushFrame triggered a harmless runtime error.

The chunk list only has two operations: append and set
to one element. The two operations are split and the append
one is sped up by storing the last element.
Corrupted data could make a very long list to search through.
