Hi,

This monster patch is the final part of restructuring the libraries.  If 
the patch doesn't work, I've included the patched sources.   With this, 
the structure of the mdocml package looks like:

  mdocXXX.o (libmdoc.h)-----+
                            |
  manXXX.o (libman.h)---(libmandoc.h) libmandoc.a (mandoc.h)
                            |  |                      |
  roffXXX.o (libroff.h)-----+  |                    main.o
   tblXXX.o                    |                    XXXterm.o
   eqnXXX.o                libmandoc.o              XXXhtml.o
                           read.o                   etc.

In other words, mandoc.h is the public interface to ALL parsing 
functionality (via mparse_readfd()).  No more having main.c dance around 
libroff and libmdoc, no more inclusion of mdoc.h and man.h in the 
front-ends.  It's all in one header file.

Internally, libmandoc.h is now the shared header file used by all 
back-end compilers.  The libmdoc.h, libman.h, and libroff.h have been 
retained for each private compiler backend.

There's no more libmdoc, libroff, and libman.  They all now live in 
libmandoc.a.

This considerably simplifies the spaghetti-mess of inclusions, 
hierarchies, and so on, although there still remains some clean-up to be 
done (chars.h, out.h, main.h, etc.).

On a related note, mdoc.3, man.3, and roff.3 have had their important 
parts merged into mandoc.3 (this is in progress, as the functions 
themselves need to be documented, although it's kind of obvious).  The 
rest I've discarded.

I also re-wrote the Makefile to be much more readable and fixable, and 
to track dependencies much closer.  This has some changes regarding the 
www site: I no longer print the ChangeLog (which, according to my logs, 
is rarely visited and anyways supplanted by cvsweb) and added eqn.7, 
alongside removing the other .3 manuals.

I notice that the compiled binary has bloated.  Any ideas why?  This 
troubles me a great deal.

Things that remain to be done in the immediate future:

  - get rid of mdoc_isdelim() (using cues somehow?)
  - merge chars.h into out.h
  - do something about out.h/main.h

Thoughts?  Reactions?
