It's a bit odd, but "make update" in src/ can also update the ports/,

doc/, and now www/ trees, but only using the "cvsup" transport.

When "make update" is run using a tree's makefile, it can also use
"cvs" (except for www/) and "svn" (only src/).

Clean up documentation and code regarding "make update":

- Increase oddness by adding support for WWWSUPFILE and NO_WWWUPDATE to
  Makefile.inc1 (analogous to PORTSSUPFILE/NO_PORTSUPDATE and
  DOCSUPFILE/NO_DOCUPDATE; WWWSUPFILE already supported by www/Makefile).

- Document all trees that support CVS_UPDATE.

- Document all trees that support SUP_UPDATE.

- Document SVN_UPDATE.

- Document NO_WWWUPDATE.

- make.conf(5) mistakenly said that *SUPFILE* had defaults.

- Add an example entry for WWWSUPFILE.
