In particular, prefer "prefix" to "postfix" as in the tool manuals, and
specify powers of 2 and 10 explicitly.

doc/eval: substitute if/then/else construct with an example making use of boolean expression composition

Since the if/then/else construct is now supported natively, showing how
to compose such a construct from basic primitives is misleading.

Add support to an if/else construct, simplify logic in expressions.

This is wrong function to check for input parameters.
Function is not needed because query_formats() already

The sh4 optimizations are removed, because the code is

The script can and will change.

Previously PIC was enabled as a magic workaround for binaries that
built fine, but failed to function at all.  This problem no longer
exists, possibly since the introduction of symbol versioning.

In ff_rtp_get_payload_type, the AVFormatContext is used for checking
whether the payload_type or rtpflags options are set. In rtpenc_chain,
the rtpctx struct is a newly initialized struct where no options have
been set yet, so no options can be fetched from there.

All muxers that internally chain rtp muxers have the "rtpflags" field
that allows passing such options on (which is how this worked before
8034130e), so this works just as intended.

This makes it possible to produce H263 in RFC2190 format with chained
RTP muxers.

Not sure if this actually happens, but we do the same check when
checking payload_type further above in the function, so it might
be needed.

This fixes encoding where the idct setting originally was set to
FF_IDCT_AUTO and dsputil chose a default idct with a non-null
permutation - even if the permutation tables were updated,
dct_quantize in x86/mpegvideoenc_template.c also checked the
value of this type variable.
