Bus Pirate buffer management revamp

The buffer management of the Bus Pirate driver has been revamped to use
grow-only buffers with a reasonable initial default size so realloc()
will not have to be called in normal operation. A side effect is the
ability to switch to a static buffer without major hassle.
Handle OOM gracefully.
