[Nel] Patches for GNU/Linux packaging

[Loic Dachary]

        Hi,

        Here is a detailed description of the change I had to do in
order to generate the debian packages. I did not try to "improve"
anything and limited myself to things that were strictly necessary for
packaging purposes. I hope you'll find this patch acceptable for the
CVS tree. Since it is bit over the 15 lines threshold, I guess it raises
the copyright assignment question once more. Any news on this side ?

        All changes were made so that the previous behaviour does not
change. I've added things and fixed bugs but did not alter the way
nel/snowballs/nelns previously behaved in any way, except for the 
installation of components of course:

        All services daemon (sno_* + *_service) are installed in /usr/sbin
        instead of /usr/bin.

        Logs go to /var/log/{snowballs,nelns}
        
        Configuration files are fetched in /etc/{snowballs,nelns}

        Local state file (login_service.udb) is in /var/games/nelns

        Data is fetched in /usr/share/games/snowballs

Makefiles:
        - Added numerous missing files in EXTRA_DIST so that 
          make dist does a proper job
        - dist-hook is used to get rid of CVS directories 
          leftovers instead of replacing EXTRA_DIST
        - LDADD mostly suppressed, there is no need to specify
          -lnelnet etc., configure does it for us
        - DIST_SUBDIRS were added where SUBDIRS = @something@ was
          used to keep make dist happy
        - Added numerous missing headers in noinst_HEADERS

acinclude.m4:
        - Reworked AM_PATH_NEL 

                Priority works as follows (higher to lower)
                . --with-nel-include and --with-nel-lib
                . --with-nel
                . nel-config

                When --with-nel* was specified, libraries were not
                collected, this was fixed. AC_CHECK_LIB stacks what it
                finds, the macro uses LDFLAGS (previously unused) to
                make sure it searches in the right place.

                Comment and removed unused variables

                Replaced MY_NEL_LIB_CHK tricks with play AC_CHECK_LIB.
                It now takes only three args.

                --without-nel triggers an error

        - Reworked AM_PATH_STLPORT

                --without-stlport triggers an error

                --with-stlport without argument is supported and DTRT

                Priority works as follows (higher to lower)
                . --with-stlport-include and --with-stlport-lib
                . --with-stlport
                It was the opposite and generated some confusion
                
                Use AC_CHECK_LIB and AC_CHECK_HEADER rather than a
                more complex combination of AC_TRY_LINK & CPPFLAGS
                tricks

                Switch to c++ using AC_LANG_* macros

nel: configure.in, acconfig.h, debug.cpp:

        - created acconfig.h and modified configure.in to define
          --without-logging that suppresses *all* log.log + stdout
          information

        - debug.cpp uses NEL_DEFAULT_DISPLAYER and NEL_LOG_IN_FILE
          to figure out if it should be verbose. The default is to
          be verbose on both channels, this is unchanged.

        - -I${top_srcdir} is added to CXXFLAGS + CFLAGS so that 
          building in a directory that is not the source directory
          works

nel-config.in:

        - New option --ldflags returns -L${libdir}. It is used
          by AM_PATH_NEL instead of --libs since AC_CHECK_LIB
          already collects available libraries.

service(_5)?.{h,cpp} + all nel services daemons and associated configure.in:

        - NLNET_SERVICE_MAIN takes two more arguments
          ConfigDir + LogDir

        - They are defined as static and default to "" so that the
          previous behaviour (create all files in current directory)
          is preserved.

        - nelns & snowballs configure.in files define the path of the 
          log + config directory (log = /var/log/nelns, config = /etc/nelns,
          typically) and daemons get them by including config.h. 

        - If config.h is not available (there are people who dislike autoconf
          for some reason ;-) the path is set to "", as it was before.

nelns + snowballs configure.in + Makefile.am:

        - added comments to AM_PATH_NEL

        - removed broken AC_CONST (if your c++ compiler does not support
          const you're in trouble and having AC_CONST work by switching to
          the proper (unused) language is not worth the effort)

        - now install daemons in /usr/sbin instead of /usr/bin

        - install configuration files *.cfg in pkgsysconf that is
          defined to $sysconf/{nelns,snowballs}

        - configuration files are fetched from /etc/{snowballs,nelns}

        - game data are fetched from /usr/share/games/snowballs

documentation:

        - various documentation typo fixed

        - recommend 4.5

Here are the patches, against Sunday 10 CVS tree.
