Use PYTHONDONTWRITEBYTECODE=1 to prevent python from creating .pyc files
in the source tree. Python 3.2 has a __pycache__ scheme [1], but before
that the only alternative seems to be to copy the source files to the
build tree to ensure the .pyc files are created there too. Just prevent
.pyc file generation for simplicity.

Considering the small amount of python code to compile (assuming sphinx
itself has .pyc around), the impact on build is neglible.

Convert deviceiobook.tmpl to RST and incorporate it into the driver API

Like the rest of our documentation, this one could use some work.  There's
no mention of ioremap() and friends, no mention of io_read*() and friends.
But we have nice documentation for all those folks writing new drivers that
do port I/O :).

The :c:func: notation has been left off of all the read*/write* functions.
There's no kerneldoc comments for them anyway, so those links will never be
live, and writing a bunch of repetitive "read a byte from I/O memory"
comments lacks appeal.

$type_struct_full and friends are only used by the restructuredText
backend, because it needs to separate enum/struct/typedef/union from
the name of the type.  However, $type_struct is *also* used by the rST
backend.  This is confusing.

This patch replaces $type_struct's use in the rST backend with a new
$type_fallback; it modifies $type_struct so that it can be used in the
rST backend; and creates regular expressions like $type_struct
for enum/typedef/union, for use in all backends.

Note that, compared to $type_*_full, in the new regexes $1 includes both
the "kind" and the name (before, $1 was pretty much a constant).

An inline function can have an attribute, as in include/linux/log2.h,
and kernel-doc handles this already for simple cases.  However,
some attributes have arguments (e.g. the "target" attribute).
Handle those too.

Furthermore, attributes could be at the beginning of a function
declaration, before the return type.  To correctly handle this case,
you need to strip spaces after the attributes; otherwise, dump_function
is left confused.
