The AC-3 encoder unconditionally references some symbols from the E-AC-3
encoder; make those references conditional to fix linking.

read_sequence_header can change width/height; therefore, re-initialize

Deprecate av_get_bits_per_sample_fmt(), which was a misnamed function.

For the moment we don't have sample formats with a non-integer number
of bytes, in that case we may need to create a new
av_get_bits_per_sample() function. In the meanwhile we prefer to adopt
this variant, since avoids divisions by 8 all over the place.

The current filter implementation should only have the cx coefficients
divided by gain in order to give the correct output scale.

They are hacks added to reuse the same scaling function for
different formats and they may cause problems when SIMD
implementation of the same functions are used along with pure
C functions.

Make yuv2yuvX16_c a function pointer for yuv2yuvX(), so that the
function pointer becomes bitdepth-independent.

The option is disabled by default, so enabling it should be documented.

This target was added to prevent some files being deleted
by make when using chains of implicit rules.  This is no
longer required.

This ensures that the special link command using cmdutils.o
only applies to the targets it should.

Current GCC versions know how to generate these instructions
properly and avoiding inline asm gives better code.  The MULH
function for ARMv5 uses the same instruction and is also not
needed any more.

The MLS64 macro remains since negating an input would normally
not be allowed as it would fail for INT_MIN.  In our uses, the
inputs never have this value and thus negating is safe.

This removes nonexisting targets from phony lists and puts them

avio_flush can fail, in particular when used with the rtmp/librtmp
protocol.

This dependency is implicitly covered elsewhere.

This option does not work, and the implied functionality is
at best pointless.
