Properly partition the build system and install some missing stuff:

* Introduce targets base-build, db-build, cgi-build.
* Introduce targets base-install, db-install, cgi-install.
* Introduce a BUILD_TARGETS variable to contain db-build and cgi-build.
* Introduce an INSTALL_TARGETS variable and fill it using BUILD_TARGETS.
* Install the whatis(1) and makewhatis(8) binaries.
* Install the apropos(1), whatis(1), and makewhatis(8) manuals.
* Install mandoc_aux.h.
* Do not build manpage(1) by default.
