lots of bugfixes

new XDRIVER with true 8..24bit support (choose color depth with d.mon)

"configure" tool to create "head" files (compiler instructions) automatically

general source code improvement:

Better Code:

      - gets() is an Achilles' heel for GRASS when used on the Web, or where
        through ignorance or malice someone can overrun an input buffer. I 
        have replaced gets() calls with the slightly safer fgets(). 
      - G_warning() and G_fatal_error() are called throughout the GRASS code
        tree as though they accepted variable arguments, i.e. 

           G_warning("Oops: error in %s, i = %d\n",string,integer);

        which is not how they were written. They were written to accept one
        char*, which they write to the screen and/or log. I have re-written 
        these functions so that they accept varargs. This change has not
        been approved by anyone, nor passed any peer review. It just seems 
        right. 
      - G_free() as as companion to G_malloc() and friends. It is annoying
        to have to replace all of the #include <malloc.h> with 
        #include <stdlib.h> so instead I just created a function to be 
        included in the gis.h header. This is portable, which is an 
        improvement.

Prototyping:

      - It's much easier to track down the mismatched arguments and implicit
        casts with prototypes. These patches provide prototypes for all of
        the src/libes, and as many other libes and modules as I have gotten
        into. 
      - In the module code, the 4.2.1v21 patch has automatically-created
        header files to provide function prototypes within each module. Some 
        of this is overkill. As I work through each module, these headers
        are fixed to be a little less intrusive. Right now, though, there 
        are still compile warnings that are the fault of this prototyping.
      - The 5.0 code has not had as much work as the 4.2-series, so there
        are still a number of bad calls lurking in the modules. With the 
        proper prototypes, maybe somebody can fix them.

Bugfixes:

     -  Functions with the wrong number of arguments. 
     -  Functions with the wrong type of arguments. 
     -  Functions with the wrong return type. Usually, this is because a
        function is allowed to default to an 'int' return, even though it 
        returns a char*, or struct*. This may work on 32-bit machines, but 
        whenever sizeof(char*) != sizeof(int) (64-bit machines, for example) 
        these functions overwrite memory, dump cores, and generally fail 
        to work. 
     -  Built-in functions without the proper headers. This leads to bad
        return types.
