Do not extract/patch/build/install the pieces of cvs (version 1.10),
which are provided by the base version 1.11 anyway. Trim pkg-plist and
bump PORTREVISION yet again.
Do not extract/patch/compile the functions (getopt/getopt_long/getline),
which are provided by libc. This unbreaks the port, because it was
the conflict in declaration of getline(3), which caused the breakage
in the first place.
