The overall strategy for now is to split the implementations into
distinct headers, but keep the generic APIs inside the main aml.h

While the current bitmask management is heavily inspired by libnuma, it is not
as easy to use has the libnuma API. This patch is an attempt to refactor
to code towards something cleaner.

- create one directory per building block in src and include
- keep one directory for tests, \
  otherwise automake make them "test suites"
- move to AC_OPENMP, which is from autoconf 2.62 (2008)

Fix a few typos in the dma_linux_seq code, that for some reason didn't
raise any flags so far. Also add a small validation to the unit test.

This patch adds the basics for a dma interface, including
type-dependent requests structures, and an API based on explicit
copy/move calls.

The APIs is flexible enough to deal with sync/async calls. The internal
design is inspired by aml_area, with the goal that create/init stay type
specific, but the core interactions are generic.
