Fixes compilation with old yasm versions.

Signed-off-by: James Almer <jamrial@gmail.com>

Some of the assembly functions e.g. ff_h264_idct_dc_add_neon
has code like:
        movrel          x14, X(ff_h264_idct_add_neon)

Linker cannot resolve them fully at link time and emits dynamic
relocations.
Use explicit labels instead so that no dynamic relocations are
needed at all.

This avoids lld complains about text relocations.

-vn/-an/-sn/-dn now works for input. Streams are still registered in
input_streams but they can't be automatically selected or mapped or
filtered.

Fully discarded streams can't be selected for output or mapped or filtered.
Previously, a few packets from such streams, probably buffered for
stream probing, would get smuggled into output files.

This breaks totally valid files that get caught in its heuristic.

This, according to the commit message, is my own doing, having asked
Michael to implement this check and providing a sample that was
"wrong". I am now atoning for my sins, and removing this hack, having
seen the light (aka that this was silly to do in the first place).

Resotores correct behavior on valid files.

This reverts commit 8e5e84c2a2.
