configure: Use LDEXEFLAGS in check_ld().

avcodec/nvenc: add support for forcing intra/idr frames

crystalhd: Use mpeg4_unpack_bframes to avoid buggy crystalhd handling

The hardware handling of packed bframes was always questionable but
it used to ok with my workaround. Today, not so much. But today we
have a bsf to unpack the bframes, so let's just use that and be
done with it.

crystalhd: Fix handling of PTS

With all the various refactorings that have happened over the years,
the current pts logic is very broken for non-trivial cases (ie: ones
where not every frame/field has a meaningful pts assocated with it).

Generally, we do not want to write AV_NOPTS_VALUE as the output
timestamp, regardless of anything else. It's better to pass zero
if there's no other information.

Additionally, interlaced content where the decoder returns each field
separately can result in the first field carrying the timestamp and
the second having AV_NOPTS_VALUE. It's clearly wrong to overwrite
the valid timestamp.

So, let's just never write AV_NOPTS_VALUE into an output frame.

Empirically, this fixed playback of interlaced mpeg2 and h.264 and
mpeg4-asp with packed b-frames in an avi container.

lavf/riffenc: Always write unexpected channel_mask.

Allows to write arbitrary channel masks also for 16bit 48kHz pcm.

aacenc: use the decoder's lcg PRNG

Using lfg was an overkill in this case where the random numbers
were only used for encoder descisions. Should increase result
uniformity between different FPUs and gives a slight speedup.

configure: add linker export script support on Darwin

This isn't a "version script" in the usual sense, since it doesn't set symbol
versions directly. Instead, the version for the whole .dylib is set in the
linker flags, and we generate a list of symbol patterns to export. This allows
us to keep our local symbols (e.g. ff_*) local on the platform.

The Darwin linker's exported_symbols_list format is a bit different than the
one used by the GNU linker. It doesn't handle local symbols at all, since when
a list is provided, all unlisted symbols are local by default; thus, we remove
local sections. It doesn't handle per-version sections, so we remove the
headers and brackets. It expects symbols to be prefixed with an underscore.
It errors if a listed symbol with no wildcards is not present in the output,
so we append an asterisk to any symbol that doesn't already end in one.
