to fix wrong function name in error message.

When a channel formula ends with a subtraction, the next formula will
otherwise have its first coefficient negated.
(cherry picked from commit 4f4e19914d)
Using AVOnce as a stack variable makes no sense as the state is lost
when the function exits.
This fixes repeated calls to av(filter/device)_register_all
Modifying data pointer when skipping samples may make it unaligned.
Workaround for Ticket6349.
This should fix the crash of ticket's testcase and a crash/regression
with avxsynth (reported by Michael Niedermayer).
Also change frame->nb_samples < max to frame->nb_samples <= max.
This improves performance. Benchmark:
./ffmpeg -filter_complex "aevalsrc=0:n=1166,firequalizer=fixed=on" -f null null

This conflict with the DJGPP libc math.h which includes a PI macro (to
M_PI).
We cannot make DJGPP POSIX only (using -D_POSIX_SOURCE) to avoid this
kind of symbols conflicts due to the lack of both posix_memalign and
memalign (DJGPP non standard function) in that POSIX mode. We currently
rely on memalign for aligned heap allocation.
This conflict with the DJGPP libc which includes a pow2 function¹

If ret is NULL, a dummy common holder is created to hold *all* the
parallel function returns, which gets written concurrently. This commit
simplify the whole logic by simply not writing to that holder when not
set.
This filter does not implement all features of MPEG7. Missing features:
- compression of signature files
- work only on (cropped) parts of the video

Add missing return value checks to suppress build warning and
remove noop ff_formats_unref() calling.
Note: most filters using ff_formats_ref() didn't have a suitable
error handling, it's a potential memory leak issue.
