Issue #1948 - Update nestegg library.

Browse source 
I separated out the AVC and AAC support code into a patch file so that
 the upstream code can be updated freely without having to re-add AVC
 and AAC support again. At least if the upstream changes are not too
 extensive...
This should effectively backport Mozilla bug 1539686, which allows the
 browser to parse the color information from WebM videos that uses HDR.
