Proper building and installation of documentation in the Makefiles.
When distcleaning, clean up doc as well.
Make documentation targets available from the top-level makefile as well,but not with separate object tree yet.
Autoconf is evil. The sysconfdir and similar variables are unusable inC includes as they contain substitutions specific to make.
Worked around by creating sysconf/paths.h which is created fromthe Makefile instead of by the configure script.
`make install' now works.
Connected the `doc' subtree to global makefiles.
All documentation is built in obj/doc (resp. doc/ if you do a stand-alone build).
Use `make docs' to make the whole documentation or `make userdocs' resp.`make progdocs' for user manual resp. developer's guide.
Added missing quotes.
Added new target "tags" to generate a tag table for Emacs.
Also made "depend" work before the tree is compiled first time.
First few FreeBSD portability fixes.
Propagate "depend" target to real top-level Makefile.
New makefiles. Includes support for out-of-source-tree builds.
