This commit stops using pkt->stream_index as index in an AVFormatContext's
streams array before actually comparing the value with the count of
streams in said array. 96e5e6ab used
pkt->stream_index in prepare_input_packet() before checking and
64063512 did likewise in
write_packets_common().

The NEON hscale function only supports X8 filter sizes and should only
be selected when these are being used. At the moment filterAlign is
set to 8 but in the future when extra NEON assembly for specific sizes is
added they will need to have checks here too.

The immediate usecase for this change is making the hscale checkasm
test easier and without NEON specific edge-cases (x86 already has these
guards).

This applies the same fix from 718c8f9a
on the 32 bit arm version of the function, fixing fate-checkasm-sw_scale
there.

We should just use a normal bl here, and the linker will add the 'x'

On windows and darwin (and modern android), the x18 register is reserved

The h264_nvenc and hevc_nvenc encoders aren't respecting the framerate in the codec context.
Instead it was using the timebase which in our use-case was 1/1000 so the encoder was behaving
as if we wanted 1000fps. This resulted in poor encoding results due to an extremely low bitrate.

Both the amf and qsv encoders already contain similar logic to first check the framerate before
falling back to the timebase.

Until now, we would have only attempted to utilize already decrypted
data if it was enough to fill the size of buffer requested, that could
very well be up to 32 kilobytes.

With keep-alive connections this would just lead to recv blocking
until rw_timeout had been reached, as the connection would not be
officially closed after each transfer. This would also lead to a
loop, as such timed out I/O request would just be attempted again.

By just returning the available decrypted data, keep-alive based
connectivity such as HLS playback is fixed with schannel.

The dec_buf seems to be properly managed between read calls,
and we have no logic to decrypt before attempting socket I/O.
Thus - until now - such data would not be decrypted in case of
connections such as HTTP keep-alive, as the recv call would
always get executed first, block until rw_timeout, and then get
retried by retry_transfer_wrapper.

Thus - if data is received - decrypt all of it right away. This way
it is available for the following requests in case they can be
satisfied with it.

Use this in vf_spp.c, where the get_pixels operation is done on
unaligned source addresses.

Hook up the x86 (mmx and sse) versions of get_pixels to this
function pointer, as those implementations seem to support unaligned
use.

This fixes fate-filter-spp on armv7.
