Makefile: add 'doc' target, include docs in install

Add a 'doc' target and 'make-docs.sh' script to build the Asciidoc documents
in 'docs/man' into installable manpages. Additionally, include these
documents (and associated symlinks) in installations from source and from
platform-specific packages.
