dashenc: Change the duration fields to 64 bit

For the last_duration field, it's mostly theoretical, but the
total_duration field more probably may need to actually be 64 bit.

vdpau: add mapping for H.264 Constrained Baseline profile and fallback

Old VDPAU drivers do not support this newly defined profile, so falling
back to Main profile is necessary for backward binary compatibility.

matroskadec: Fix read-after-free in matroska_read_seek()

In matroska_read_seek(), |tracks| is assigned at the begining of the
function. However, functions like matroska_parse_cues() could reallocate
the tracks and invalidate |tracks|.

This assigns |tracks| only before using it, so that it will not get
invalidated elsewhere.

mov: Fix handling of zero-length metadata values

Since 3cec81f4d4, a zero-length metadata value would try to
allocate 2*0 bytes, where av_malloc() returns NULL.

Always add one to the allocated length, to allow space for
a null terminator in the zero-length case.

Incidentally, this fixes fate-alac on RVCT 4.0, where a compiler
bug seems to mess up the mov muxer to the point that it writes
the wrong sort of metadata. Previously this bug was undetected,
but since 3cec81f4d4 such mov files started returning
AVERROR(ENOMEM) in the mov demuxer.
