- 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.

Add include path to the ar9300 HAL.

Remove an un-needed trailing / after OBJDIR.

Nitpicked by: juli

Make the existing ath tools build again.

* add missing includes to quieten warnings
* fix an inline function decl to have a return type
* since .h files are created during the build (opt_ah.h, ah_osdep.h)
which modify the behaviour of the HAL include/source files,
include OBJDIR in the path so the #include's work.

The tools should now build when the directory is added to LOCAL_DIRS
during a make buildworld.

fix build

add athrd tool that dumps ath hal regulatory info; note this is soon to
obsolete but commit now so it's available for anyone that's interested

bring in diagnostic tools that are useful now that we have hal source code
