Add accessor functions for iterating over segments. A segment
...
can be in bus address space, physical memory space or virtual
memory space.

Rename bus_space to bus (i.e. drop _space). This makes the
...
API match the convenience macros in <sys/bus.h>. Bus space
can now reference both bus and busdma.

0c2b180a35
Add a C libary and a Python module that implements an API similar
...
to bus_space(9) and that uses the proto(4) driver for talking to
hardware. If the I/O resource is a memory mapped I/O resource,
then mmap(2) will be attempted to avoid read(2)/write(2) overhead.
