Add TSO support on VLAN in fconfig(8).

Reviewed by: thompsa

- Use size_t instead of int when appropriate;
- Use C99 sparse initialization.

With these changes ifconfig(8) is WARNS=2 clean.

Replace clone_setcallback() with a new function clone_setdefcallback()
that selects a callback from an interface prefix name. This allows us to
report a meaningful error when the user types 'ifconfig wlan0 create',
for example, and also kills some redundant code.

back out unintended change

o distinguish between adhoc and ahdemo modes
o do not require 1/2 and 1/4 rate channels be present in the
calibration list when doing a gsm regulatory change; the
existing 900MHz cards are not self-identifying so there is
no way (using the calibration channel list) to check

add duplicate cmd entries for vlan and vlandev that are marked !clone
so they can be used when not doing a create operation

Fix handling of create operation together with setting other parameters:
o mark cmds/parameters to indicate they are potential arguments to a clone
operation (e.g. vlantag)
o when handling a create/clone operation do the callback on seeing the first
non-clone cmd line argument so the new device is created and can be used;
and re-setup operating state to reflect the newly created device

o replace special handling of clone operations by a clone callback
mechanism
o change vlan cloning to use callback and pass all vlan parameters
on create using the new SIOCREATE2 ioctl
o update vlan set logic to match existing practice

Revert to setting vlan and vlandev parametes synchronously, as soon
as both have been read from the command line. Still use the callback,
but this time only to verify that both vlan and vlandev have been
found on the command line.

This should allow for control over the relative order of processing
parameters, which is needed to satisfy some caveats of the if_vlan
driver. E.g., MTU cannot be changed on a vlan interface until it's
attached to its parent.

Eliminate some unneeded code bits.

Use a callback to set up a vlan interface so that "vlan"
and "vlandev" commands can be specified in any order.
This makes the code more compact and clear as well.

Fix special status reporting. Prior to the reorg there was
special-purpose code to display status for an interface for
state that was not address-oriented. This status reporting
was merged in to the address-oriented status reporting but
did not work for link address reporting (as discovered with
fwip interfaces). Correct this mis-merge and eliminate the
bogus kludge that was used for link-level address reporting.

o add an af_other_status method for an address family for
reporting status of things like media, vlan, etc.
o call the af_other_status methods after reporting address
status for an interface
o special-case link address status; when reporting all
status for an interface invoke it specially prior to
reporting af_other_status methods (since it requires the
sockaddr_dl that is passed in to status separately from
the rtmsg address state)
o correct the calling convention for link address status;
don't cast types, construct the proper parameter

This fixes ifconfig on fwip interfaces.

Overhaul to cleanup some of the tangled logic that's grown over the years.

o break per-address family support out into separate files
o modularize per-address family and functional operations using
a registration mechanism; this permits configuration according
to which files you include (but beware that order of the files
is important to insure backwards compatibility)
o many cleanups to eliminate incestuous behaviour, global variables,
and poor coding practices (still much more to fix)

The original motivation of this work was to support dynamic addition
of functionality based on the interface so we can eliminate the various
little control programs and so that vendors can distribute ifconfig
plugins that support their in-kernel code. That work is still to be
completed.

o Update 802.11 support for all the new net80211 functionality; some
of these operations (e.g. list *) may be better suited in a different
program

De-__P, use ansi function definitions

o Reduce userland inclusion of kernel headers -- remove unneeded include
of <sys/mbuf.h>.
