Robert Jördens 3165c680d6 dma: don't swap buffers
* This uses a new closure-based method to the DMA HAL implementation which
  gives access to the inactive buffer directly.
* It removes changing addresses, the third buffer for DBM, the inactive
  address poisoning, and allows the cancellation of the redundant repeat
  memory barriers and compiler fences.
* This is now around 20 instructions per buffer down from about 100 cycles
  before.
* Also introduces a new `SampleBuffer` type alias.
* The required unpacking of the resources structure is a bit annoying
  but could probably abstraced away.

TODO:

* Test
* Adapt `lockin`
