Summary: random buffer snd_output_t issues
Description:
There are several issues with using a snd_output_t acquired from
snd_output_buffer_open(). These cause random segfaults because of
writing/reading invalid memory.
The attached patch fixes those issues.

patch to fix the issues.
These include:
- snd_output_buffer_need might not resize the buffer to be big enough, if
huge sizes are required.
- calculating the needed buffer size does not take care of the terminating
null byte vsprintf puts at the end. So in rare cases, the buffer is
exactly one byte too small. Use vsnprintf instead to guard against these
problems.
- snd_output_buffer_print does not correct the size member for the number
of bytes added.
