Add support for persistent device memory.
Add a function to allocate memory belonging to a specific device,
so that the operating system can DMA straight into it for zerocopy,
and also avoid some clearing. Also, this allows up-front memory
allocation in the kernel at program startup; memory allocation is
otherwise done per-transfer, which can fail in a system where memory has become
fragmented over time).
This mirrors new functionality going into Linux' USB stack (recently
reviewed and acked upstream); only Linux is supported as a backend
currently.
[Chris Dickens] Modified to fix doxygen documentation, correct parameter
naming, reposition function declarations, and address a missing request
during the patch review process.
