Let the target algorithm be running in the background and buffer data
continuously through a FIFO. This reduces or removes the effect of latency
because only a very small number of queue executions needs to be done per
buffer fill. Previously, the many repeated target state changes, register
accesses (really inefficient) and algorithm uploads caused the flash
programming to be latency bound in many cases. Now it should scale better
with increased throughput.

This patch adds the initial dual flash bank support for devices such
as the stm32xl family.

As the stm32 flash loader now uses the preprocessor change extension
so that it used by default.

Add comments to assembly flash loader for STM32. Add tiny improvement in
size of the algorithm (40 vs 48 bytes) and tiny speed improvement (~1.5%,
as time is wasted on waiting for end of operation anyway).
