Mk: Cleanup after moving apply-slist earlier.

all: Remove all other $FreeBSD keywords.

Remove # $FreeBSD$ from Makefiles.

Add USES=xorg USES=gl, ports categories j

Add USES=xorg and USES=gl to ports in categories starting with 'j'
While here, try to sprinkle other USES (mostly gnome and sdl) as needed.

Convert to UCL & cleanup pkg-message (categories h-k)

Fix whitespace issues (mixed tab/spaces, alignment) in a few ports.

This round is @FreeBSD.org residents except teams.

Cleanup $() variables in ports Makefiles.

Mostly replace with ${}, but sometime, replace with $$() because it is
what was intended in the first place. (I think.)

Prevent collision with getline(3)

Remove ${PORTSDIR}/ from dependencies, categories h, i, j, k, and l.

Cleanup plist

- Fix build when only CANNA is defined in PORT_OPTIONS.
- Simplify PORT_OPTIONS handling.

PR:	ports/190396

Remove the last @comment $FreeBSD$ from plists.

- STAGEDIR support.
- Use new syntax for LIB_DEPENDS.

Fix properties on pkg-plist

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

Mark jobs unsafe

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

Fix syntax error

Spotted by:	bmake exp-run

- Trim old-style header.
- Use OPTIONS_DEFINE.

- Get Rid MD5 support

With hat:       portmgr (myself)

- Fix SIGSEGV problem on amd64.
- Convert ConvDesc and ModeTable to a linked list, deprecate complex
  realloc-based memory management.
- Add missing "${CAT} ${PKGMESSAGE}" in the post-install target.
- Regenerate patches.

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

Prioritize $JSERVER over "CcWnn.Jserver" in the resource file for
server name lookup for consistency.  Bump PORTREVISION.

Fix a typo in WITH_WNN7.

Stop using :u modifier because old make(1) does not understand it.

Use mode 01777 for unix domain socket directory and drop access
privilege to the unix domain socket from group and others.

This should be no user-visible change.

Use Unix domain socket for Wnn backend (jserver) by default.

Fix packing list when all of WITH_*WNN* knobs are disabled and
only WITH_CANNA is enabled.

Spotted by:     WATANABE Kazuhiro

- Disable TCP transport by default (WITH_TCP knob) because unix
  domain socket is used in most cases.

- Use "localhost" when TCP transport enabled.

Use 127.0.0.1 for incoming communication socket (internally-used
one) instead of INADDR_ANY.  This is not a user-visible change of the
original functionality.

- Simplify japanese/kinput2-* variants into a single japanese/kinput2.
  The japanese/kinput2 port supports Canna, FreeWnn, and SJ3 by default.
- OPTIONify backend support selection.
- Take maintainership.

japanese/kinput2 is repo-copied from japanese/kinput2-freewnn.
