patch to make dynamically loadable modules possible

This patch makes dynamically loadable lookup modules possible.

Based on Tim's patch, heavily modified, and I had to add lots of
makefile foo...

The one thing I haven't quite sorted out yet is how to install
the modules. I started it, but LOOKUP_MODULE_DIR doesn't seem
right, it should have some prefix like LIBDIR or BINDIR or
something... Someone else can probably figure that out much
much faster than me.

So. Known bugs:
* module install not done
* module name list that is built during loading
is never freed (see addlookupmodule)
* the library ending is hard-coded to .so

* well, loadable module support :)
* no more src/lookups/*.h files (except lf_functions.h)
* all lookup functions added dynamically, so can all be static now

* lf_quote.c and lf_check_file.c are always linked in

* LOOKUP_XXX=2 was previously a valid setting for compiling it in
* the "Lookups:" printout line changed to
"Lookups (built-in):"
