Rather than using hidden includes (with cicular dependencies),
directly include only the header files needed. This reduces the
unneeded spamming of various headers into lots of files.

For now, this leaves us with very few modules including vnet.h
and thus needing to depend on opt_route.h.

Step 1.5 of importing the network stack virtualization infrastructure
from the vimage project, as per plan established at devsummit 08/08:
http://wiki.freebsd.org/Image/Notes200808DevSummit

Introduce INIT_VNET_*() initializer macros, VNET_FOREACH() iterator
macros, and CURVNET_SET() context setting macros, all currently
resolving to NOPs.

Prepare for virtualization of selected SYSCTL objects by introducing a
family of SYSCTL_V_*() macros, currently resolving to their global
counterparts, i.e. SYSCTL_V_INT() == SYSCTL_INT().

Move selected #defines from sys/sys/vimage.h to newly introduced header
files specific to virtualized subsystems (sys/net/vnet.h,
sys/netinet/vinet.h etc.).

All the changes are verified to have zero functional impact at this
point in time by doing MD5 comparision between pre- and post-change
object files(*).

(*) netipsec/keysock.c did not validate depending on compile time options.

Use db_printsym to lookup and print the function pointers.

Fix handling of shortgi: use the local configuration (and implicitly
device capabilities) to decide whether to use short gi. Drivers
inspect ni_flags to decide whether to send a frame w/ short sgi.

RIFS support; needs driver callback for dynamic state change

MIMO power save support; still needs callbacks for notifying drivers
of dynamic state change in station mode.

Crypto api changes:
o don't use the key index to identify when the driver has been
asked to allocate a key slot, use an explicit flag; allows

Crypto api changes:
o don't use the key index to identify when the driver has been
asked to allocate a key slot, use an explicit flag; allows
drivers to force s/w fallback for entries in the global table
o change callback api to allocate driver resources for a crypto key:
- de-const the key parameter so drivers can muck with the flags
- on callback failure don't automatically try to setup s/w crypto;
instead the driver must now mark the key entry for s/w crypto and
the caller will re-attach the cipher module

NB: api change permits drivers more control over fallback to s/w
crypto (e.g. based on a limited number of h/w key slots)

Minor cleanup of vap create work:
o add IEEE80211_C_STA capability to indicate sta mode is supported
(was previously assumed) and mark drivers as capable
o add ieee80211_opcap array to map an opmode to the equivalent capability bit
o move IEEE80211_C_OPMODE definition to where capabilities are defined so it's
clear it should be kept in sync (on future additions)
o check device capabilities in clone create before trying to create a vap;
this makes driver checks unneeded
o make error codes return on failed clone request unique
o temporarily add console printfs on clone request failures to aid in
debugging; these will move under DIAGNOSTIC or similar before release

Multi-bss (aka vap) support for 802.11 devices.

Note this includes changes to all drivers and moves some device firmware
loading to use firmware(9) and a separate module (e.g. ral). Also there
no longer are separate wlan_scan* modules; this functionality is now
bundled into the wlan module.
