japanese/canna-lib: fix build with clang 15

During an exp-run for llvm 15 (see bug 265425), it turned out that
japanese/canna-lib failed to build with clang 15:

  crxgram.c:421:33: error: incompatible integer to pointer conversion passing
'int' to parameter of type 'char *' [-Wint-conversion]
                  alert("unknown operation %c", op);
                                                ^~
  rkc.c:2741:38: error: incompatible integer to pointer conversion passing 'int'
to parameter of type 'unsigned char *' [-Wint-conversion]
    nkanji = _RkwGetSimpleKanji(cxnum, dicname, cbuf, len,
                                       ^~~~~~~

This is mostly expected as canna-lib is very old K&R code, and clang 15
has -Wint-conversion as an error by default.

Pass -Wno-error=int-conversion in CCOPTIONS to make the warning
non-fatal. This should work for both clang and gcc.

Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

japanese: remove 'Created by' lines

MASTER_SITES cleanup.

- Replace ${MASTER_SITE_FOO} with FOO.
- Merge MASTER_SITE_SUBDIR into MASTER_SITES when possible. (This means 99.9%
  of the time.)
- Remove occurrences of MASTER_SITE_LOCAL when no subdirectory was present and
  no hint of what it should be was present.
- Fix some logic.
- And generally, make things more simple and easy to understand.

While there, add magic values to the FESTIVAL, GENTOO, GIMP, GNUPG, QT and
SAMBA macros.

Also, replace some EXTRACT_SUFX occurences with USES=tar:*.

Two imake related changes:

1) Move -a from XMKMF command variable to a new XMKMF_ARGS variable.
   For ports that don't need -a introduce USES=imake:notall.
   This way ports no longer have to redefine XMKMF.

2) xmkmf -a runs imake with the flags in IMAKECPPFLAGS as extra arguments
   to set CPP, CC and CXX.  This creates the top Makefile, and then xmkmf
   runs make Makefiles.  This Makefiles target runs imake for each
   subdirectory but these imake invocations did not have the flags from
   IMAKECPPFLAGS so the resulting makefiles used the wrong C preprocessor
   when clang is used (/usr/bin/cpp instead of /usr/local/bin/tradcpp).
   Instead of letting xmkmf pass IMAKECPPFLAGS from the environment to
   imake let imake handle IMAKECPPFLAGS itself just like it handles
   IMAKEINCLUDE.

   This exposed configure errors in x11-clocks/mouseclock and x11-wm/fvwm.

Approved by:	portmgr (bapt)

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

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.
