unlike reap_screen(), capture_screen() can be used to populate buffer
without touching the timestamps. this is useful for upcoming commits
which implement a real time caption stream.
This fixes builds with --disable-vfp.
Checking for the armv6 cpu flag is incorrect, since vfpv2 isn't
armv6 specific.

moves the screen_changed bit and the bprint_clear into reap_screen() so
the logic is centralized and callers do not need to touch the bit or the
buffer before calling reap_screen()
The function documentation explicitly mentions it needs to be a multiple of 4.

In many older QuickTime files, the audio format, or "fourcc", is
0x00000000. The QuickTime File Format Specification states the following
regarding this situation:
"This format descriptor should not be used, but may be found in some
files. Samples are assumed to be stored in either 'raw ' or 'twos'
format, depending on the sample size field in the sound description."
MPlayer handles this logic by itself, but FFmpeg/FFplay currently does
not.

In the spirit of commit a956840cbc. Simple method to reproduce:
pass -vstats_file /dev/full to ffmpeg.
All raw fclose usages in ffmpeg.c taken care of here.

This is faster; precision assured as result is a float.

Use two separate functions, depending on whether VFP/NEON is available.
This is set to require armv5te - it uses blx, which is only available
since armv5t, but we don't have a separate configure item for that.
(It also uses ldrd, which requires armv5te, but this could be avoided
if necessary.)
