- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Typo and mdoc(7) style fixes.

Fix an mdoc(7) nit.

Globally replace u_int*_t from (non-contributed) man pages.

The reasoning behind this, is that if we are consistent in our
documentation about the uint*_t stuff, people will be less tempted to
write new code that uses the non-standard types.

I am not going to bump the man page dates, as these changes can be
considered style nits. The meaning of the man pages is unaffected.

Document the fact that passing in a count of zero to the bus_space functions
will result in undefined behaviour.
Taken from NetBSD's bus_space(9).

Revert r216134. This checkin broke platforms where bus_space are macros:
they need to be a single statement, and do { } while (0) doesn't work in this
situation so revert until a solution can be devised.

Disallow passing in a count of zero bytes to the bus_space(9) functions.

Passing a count of zero on i386 and amd64 for [I386|AMD64]_BUS_SPACE_MEM
causes a crash/hang since the 'loop' instruction decrements the counter
before checking if it's zero.

Correct the list of bus_space_*_stream_[1248] functions in the
STREAM FUNCTIONS section:

- Really list only and all *_stream_* functions.
- Don't list their arguments (it's pointless).

document the various bus_space_*_stream_? functions...

Overhaul the markup.

Don a flack jacket and start to document the FreeBSD bus_space
implementation. I took the NetBSD man page, and hacked it to, I hope,
to reflect the preliminary version of the bus space that Justin Gibbs
committed as part of the CAM integration in FreeBSD 3.0.

This isn't perfect, but it is better than we have now (which is, ahem,
nothing). Please coordinate changes to the file through me through
the 6.0 release.
