This case should not be possible if the input has a exponent within
the valid range

This reverts commit 0269fb11.

Otherwise the exponent could eventually underflow

The assert in ffmmal_stop_decoder() could trigger sometimes. The
packets_buffered counter was indeed not correctly maintained, and
packets were not subtracted from it if they were still in the waiting
queue.

For some reason, this happened especially with VC-1.

It was only useful for very specific testing purposes
and appears to be currently partially broken.

Trim unneeded leading components and trailing zeros.
Move the formating code in a separate function.
Use the function also to format the default value, it was currently
printed as plain integer, inconsistent to the way it is parsed.

Similar to the -re option in ffmpeg that only works for input files.
Can be used at any place in the filter graph.

Similar to testsrc, but using drawutils and therefore
supporting a lot of pixel formats instead of just rgb24.
This allows using it as input for other tests without
requiring a format conversion.
It is also slightly faster than testsrc for some reason.

The buffer needs s->bpp bytes, at maximum currently 10.
Assert that s->bpp is not larger.

This fixes a stack buffer overflow.

The return type of strlen is size_t, i.e. unsigned, so if pd->buf_size
is 3, the right side overflows leading to a wrong result of the
comparison and subsequently a heap buffer overflow.
