0e84eee719 libavutil/fifo: Fix fifo grow step
Fifo was reallocating always to twice of the requested size.
This fixes it to reallocate to requested size, or twice of the
original size - whichever is greater.

d12b5b2f13 build: Split test programs off into separate files
This avoids spurious library rebuilds when only the test program
code is changed and simplifies the build system.

1735440773 fifo: use av_freep()
With this change libavutil uses av_freep() everywhere where it makes sense.
Remaining av_free() use in it has the used pointer become inaccessible quickly
soo zeroing makes no sense.

0871ae1a93 Make av_fifo*_read() ignore the available amount of data.
This is more efficient as in practice the check is redundant most of the
time. Callers which do not know if enough data is available have to check
it with av_fifo_size(). Doing the check in *read() means the caller has
no choice to skip the check when its known to be redundant.
Also the return value was never documented in a public header so
changing it should not break the API. Besides this fixes the case where
read() failed on a 100% full fifo.
