Mk: Cleanup after moving apply-slist earlier.

all: Remove all other $FreeBSD keywords.

Remove # $FreeBSD$ from Makefiles.

Convert most NO_INSTALL_MANPAGES to USES=imake:noman

With hat:	portmgr

- STAGEDIR support.
- Add LICENSE.
- Remove GCC dependency.

Fix properties on pkg-plist

Add NO_STAGE all over the place in preparation for the staging support (cat:
japanese)

New USES imake to handle the dependency on imake.

This uses accept 'env' as an argument for ports that do use their own or a
different do-configure target.

Modify xmkmf so it accept IMAKECPPFLAGS as default flags for imake and pass it
to the called imake.
Modify xorg-cf-files (the FreeBSD.cf configuration file) to allow CppCmd to be
overwritten.
Pass CppCmd CcCmd and CplusplusCmd via command line to each call of imake via
IMAKECPPFLAGS
Pass IMAKE_DEFINE with the above arguments to MAKE_ARGS so that imake spawned
from Makefile generated by a previous
imake also inherit the defined CppCmd CcCmd and CplusplusCmd.
Make imake use devel/tradcpp all the time, so that when buidling with clang we
do not depend on gcc's cpp.
Make imake respect CC and CXX
Make imake respect USE_GCC (if set imake will use gcc's cpp).

While here:
- Remove a couple of indefinite articles from comments
- Trim headers
- Fix a couple of ports to build with clang or use: USE_GCC=any
- Fix a now useless redefinition of the extraction chain
- Fix a typo in japanese/Wnn7-lib bundled imake template definitions
- Fix some XMKMF execution with no env specified
- Use options helper in x11/xautolock to simplify the port

Trim old-style header and add style clean-ups.

Force numerous ports that fail to build with clang over to instead always
rely on gcc.  The patch uses the new USE_GCC=any code in Mk/bsd.gcc.mk to
accomplish this.

The ports chosen were ports that blocked 2 or more ports from building with
clang.  (There are several hundred other ports that still fail to build with
clang, even with this patch.  This is merely one step along the way.)

Those interested in fixing these ports with clang, and have clang as their
default compiler, can simply set FORCE_BASE_CC_FOR_TESTING=yes.

For those who have gcc as their default compiler, this change is believed
to cause no change.

Hat:		portmgr
Tested with:	multiple runs on amd64-8-exp-bcm and 9-exp-clang, with various
		combinations of patch/no-patch and flag settings.

- Get Rid MD5 support

With hat:       portmgr (myself)

Convert most of remaining ports that depend on xorg-libraries to
modular xorg.

- supply corresponding USE_XORG for all imake-using ports that need it
- USE_IMAKE no longer implies USE_XLIB in absence of USE_XORG
- retire USE_X_PREFIX which is not really used anywhere after the
  above change
- a few minor nits like whitespace and SF macro

Tested by:      2 tinderbox runs by pav
Approved by:    portmgr (pav)

- Separate the server part and the library part from japanese/sj3, and
  remove japanese/sj3.
- Use localhost as the default listen address instead of INADDR_ANY.
- Add "servername" directive to serverrc.
- Fix incorrect descriptions in serverrc.
- Take maintainership.
