BIRD uses hacked LinuxDocTools for building documentation, keeping some
parts locally and using remaining parts from system-installed one. This
setup breaks when LinuxDocTools makes some internal changes and is hard
to keep consistent.
Just include full LinuxDocTools code (both hacked and unmodified parts)
to avoid consistency issues. Note that we still need some binaries from
LinuxDocTools, so it still needs to be installed to build documentation.
Also removed the lib-dir merging with sysdep. Updated #include's
accordingly.
Fixed make doc on recent Debian together with moving generated doc into
objdir.
Moved Makefile.in into root dir
Retired all.o and birdlib.a
Linking the final binaries directly from all the .o files.
From now, you can just `make userdocs' in doc, no need to use ugly scripts.
Also, `make progdocs' builds the programmer's documentation in HTML,
LaTeX version to come later.
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.
