This fixes parallel FATE (make fate -j4) failing under valgrind with:
 Syscall param ioctl(TCSET{S,SW,SF}) points to uninitialised byte(s)
    at 0x5D98B23: tcsetattr (tcsetattr.c:88)
    by 0x43D66C: term_init (ffmpeg.c:734)
    by 0x43CD8D: main (ffmpeg.c:5071)
  Address 0x7fefffdd0 is on thread 1's stack
  Uninitialised value was created by a stack allocation
    at 0x43D5B0: term_init (ffmpeg.c:716)

The same as av_fast_malloc but uses av_mallocz and keeps extra
always-0 padding.
This does not mean the memory will be 0-initialized after each call,
but actually only after each growth of the buffer.
However this makes sure that
a) all data anywhere in the buffer is always initialized
b) the padding is always 0
c) the user does not have to bother with adding the padding themselves
Fixes another valgrind warning about use of uninitialized data,
this time with fate-vsynth1-jpegls.

This combination is quite odd and almost certainly a bug if

The tool is useful for testing the internal arithmetic evaluation engine
(indeed I plan to use it in FATE), and provides a handy calculator when
you can't rely on bc ;-).

They allow to implement the if/then/else logic, which cannot be
implemented otherwise.

For example the expression:
A*B + not(A)*C

always evaluates to NaN if B is NaN, even in the case where A is 0.

Change log level from ERROR to WARNING and provide more specific
information in the message itself.

Fixes compilation with NASM.

Overall almost 4% faster, idct_add down from 350 to 85 cycles, idct_dc_add
down from 83 to 30 cycles.

squash: rv34 idct rearrange partial register loads

Implement 1-pass inverse transform and reconstruction for inter blocks.

This reworks the frame skipping code such that the reference
buffers are still updated according to the header.
However it also ensures that the current frame will not end
up in any reference buffer.
Also fixes a hang with frame-multithreading, probably because
get_buffer was already called and would have reset the progress,
however the frame could remain in framep due to the missing update
(or it could be assigned to next_framep and a skip_frame skip would
then write it into framep - there might be even more failure modes).
Sample might become available at samples/nsv/vp8.nsv
