Fix size_t truncations in media for 64-bit VS 2015

These changes are enough to get the media portions of Chromium building
with VS 2015 in 64-bit gn builds. The changes are all to fix warnings
about truncation from size_t to smaller types.

PTAL.

The surprising indenting in packet_storage_unittest.cc is straight out of git cl

Yeah, I'm not a fan of the newly-forced indenting rules (especially since nobody
consulted me, the primary owner of media/cast).  But, let's not have that block
your change.
