According to the PIFF specification[1] the base_data_offset field MUST be
omitteed. See section 5.2.17. Since the ISMV files created by libavformat
state that they are 'piff' compatible via 'ftyp' box, this needs to be
corrected.

Prevent spurios EIO on EOF.

Fix the mispresented EINVAL for EOF on partial files, among the other.

RIFF chunks are aligned to 16bit according to the specification.

Ease switching version in the future and make evident why that value.

This should fix misdetection of AVS files as AviSynth scripts
when AviSynth support is enabled (Bugzilla #357).

output-example links against swscale, which depends on avutil.  In standard
configurations, by pure good luck, the libs before swscale pull in all of
swscale's dependencies and linking succeeds.  However, in some configurations
like --disable-asm this is not the case and linking fails.

Hardcode the dependency to avoid a more general Makefile refactoring.

Most formats do not support negative timestamps, shift them to avoid
unexpected behaviour and a number of bad crashes.
