Introduce NOIEEE80211 option, by which IEEE 802.11 support is dropped from
ifconfig(8) in crunched binaries. This saves ~9KB for, e.g., m68k.

Cosmetic changes. No functional changes.

Replace ".PATH ${SRCDIR}" before including Makefile.common to ensure the
correct order of search path.

Factor out a common part in Makefile's of ifconfig and x_ifconfig.

Rename sbin/ifconfig/Makefile.inc to Makefile.common; the former can
potentially conflict with bsd.subdir.mk.

Define NOMAN before including bsd.own.mk to set MKMAN=no appropriately.

Add small.

Make the definition of CRUNCHOPS independent of SMALLPROG_INET6 / USE_INET6.

Distrib/sparc64/instfs now builds again.

use CRUNCHOPS for a crunched prog

Define PROG here since Makefile.inc no longer defines it.

Use ${.CURDIR} when referring to a relative source directory.

-CPPFLAGS+= -I${SRCDIR}

Otherwise, system util.h is not included when compiling ifconfig.c, the
snprintb prototype is missing, and the flags don't get printed correctly
on hp700.

Let us add/remove features from ifconfig, such as support for
various address families (inet, inet6, iso, atalk) and protocols
(802.11, 802.3ad, CARP), simply by trimming the list of sources in
the Makefile. This helps one customize ifconfig for an embedded
device or for install media, and it eliminates a lot of grotty
#ifdef'age. Now, the ifconfig syntax and semantics are finalized
at run-time using the constructor routines in each address-family/protocol
module.

(In principle, ifconfig could load virtually all of its syntax from
shared objects.)

Extract a lot of common code into subroutines, in order to shrink
the ifconfig binary a bit. Make all of the address families share
code for address addition/replacement/removal, and delete "legacy"
code for manipulating addresses. That may have broken atalk and
iso, despite my best efforts.

Extract an include file, Makefile.inc, containing the make-fu that
both ifconfig and x_ifconfig share.

Sprinkle static. Change some int's to bool's. Constify.

Add RCS Ids to carp.c and env.c. Move media code to a new file,
media.c. Delete several unneeded header files.

Set, reset, and display the IEEE 802.11 attribute, 'dot11RTSThreshold'.

Bug fix: do not require both a interface address and a destination
address for point-to-point interfaces, but accept a interface
address by itself.

Overhaul ifconfig. Use fewer global variables. Take a leap toward
improved modularity and extensibility.

In the new architecture, a directed graph of argument-matching
objects (match objects) expresses the set of feasible ifconfig
statements. Match objects are labelled by subroutines that provide
the statement semantics.

Many IPv4, IPv6, 802.11, tunnel, and media configurations have been
tested.

AppleTalk, ISO, carp(4), agr(4), and vlan(4) configuration need
testing.

Rework how SMALLPROG was being used and how INET6 support was enabled.
There's two variables added to Makefile.crunch:

SMALLPROG If 1, add SMALLPROG=1 to CRUNCHENV. [default: 1]
This can be used by various Makefiles to
determine if a `small' version of the program
is required.

SMALLPROG_INET6 If 1 and SMALLPROG == 1, add SMALLPROG_INET6=1
to CRUNCHENV. [default: 0]
This can be used by various Makefiles to
determine if the `small' version has INET6
support enabled.

Only enable SMALLPROG_INET6 for programs on the ramdisks that have INET6 in
the appropriate kernel, and cleanup INET6 setting.
(Note: this means that sysinst won't get INET6 support if the kernel
it's running on doesn't have it).

This change saves a fair bit of space on various install images
(including i386 ramdisk-{ps2,small,tiny}) that didn't have INET6 in
the kernel but were unconditionally getting INET6 support in their tools.
