avformat/oggdec: Fix integer overflow with invalid pts
If negative pts are possible for some codecs in ogg then the code needs to be
changed to use signed values.

libavformat/matroskadec: fix unsigned overflow to improve seeking
When seeking a file where codec delay is greater than 0, the timecode
can become negative after offsetting by the codec delay. Failing to cast
to a signed int64 will cause the check against skip_to_timecode to evaluate
true for these negative values. This breaks the "skip_to" seek mechanism.

Make ffmpeg a static_library in non-component builds
In non-component builds ffmpeg must be a static library because
otherwise its .obj files are linked directly into chrome.dll, causing
100s of KB of unneeded global variables and code to be pulled in, even
in official builds.
The immediate affect of this is for ff_cos_65536_fixed (and its
mip-maps), totaling almost 128 KiB of global variables to no longer be
linked in. This change also enables future changes that will keep many
other globals and code out of chrome.dll.
