- 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.

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.

add -b option to suppress the banner

add -z option to zero driver statistics (but note we don't yet zero
stats obtained from the hal)

unbreak -o

TDMA support for long distance point-to-point links using ath devices:
o add net80211 support for a tdma vap that is built on top of the
existing adhoc-demo support
o add tdma scheduling of frame transmission to the ath driver; it's
conceivable other devices might be capable of this too in which case
they can make use of the 802.11 protocol additions etc.
o add minor bits to user tools that need to know: ifconfig to setup and
configure, new statistics in athstats, and new debug mask bits

While the architecture can support >2 slots in a TDMA BSS the current
design is intended (and tested) for only 2 slots.
