Introduce a stable ABI

The current mtdev is not ABI stable, and the upcoming additions
to the kernel api will break ABI. This patch starts the process
of keeping binary compatibility with old programs, by moving the
abi-specific parts under a special flag, MTDEV_NO_LEGACY_API,
and makes sure the internal parts compiles with MTDEV_NO_LEGACY_API
set. This way, older programs will still work, old programs will
still compile, and new programs will be able to use the additions.
