06f94149c6 swresample/resample: optimize exact_rational=on:linear_interp=on case
separate dsp.resample to dsp.resample_common and dsp.resample_linear
and choose to call faster resample_common even when linear_interp=on
when c->frac and c->dst_incr_mod are both zero

speed up resampling when exact_rational and linear_interp are both
enabled because exact_rational force c->frac and c->dst_incr_mod to
be zero when soft compensation does not happen

benchmark on exact_rational=on:linear_interp=on

b5f0eac068 swr: rename swresample_dsp init functions to swri_resample_dsp
The swresample_ prefix is not for internal functions

23a9edf531 Partially revert "swr: add prototypes for resample dsp functions"
Prototypes are not needed anymore now that the x86 functions don't
include resample_template.c

The DO_RESAMPLE_ONE macro is removed for that same reason as well.

7f4dfbd080 swr: add prototypes for resample dsp functions
Should fix compilation failures with MSVC and any other compiler
without inline asm support.

7128a35f8c swr: split out DSP functions.
DSP bits of swri_resample go into their own mini-DSP functions; DSP
init goes from a per-call branch in multiple_resample to a proper
DSP init routine; x86 bits go into x86/; swri_resample() moves out of
resample_template.c into resample.c because it's independent of DSP
code or sample type; multiple_resample() is simplified.
