(1) Add new USE_BISON directive, which will expand to BUILD_DEPENDS on

    4-current post bison-removal and to a no-op otherwise.  Note this
    should only be used when the software in question uses a feature
    in bison that is not in byacc -- otherwise it should be patched to
    use byacc (or detect the absense of bison correctly).  [bsd.port.mk]

(2) Do not assume all category names are lowercase.  In particular,
    remove package links by removing them one by one, instead of doing
    a "rm [a-z]*/${PKGNAME}.tgz". [bsd.port.mk]

(3) Do not assume the category name doesn't include a path separator
    (/).  Make links accordingly. [bsd.port.mk,README.category,README.port]

(4) Do not assume all category makefiles are directly under
    ${PORTSDIR}.  [bsd.port.mk,README.category]

(5) Add new "package-name" target which prints out the directory name
    to be used in the parent README.html.  [bsd.port.subdir.mk]

(2) through (5) are in preparation for going to multi-level
categories.  They shouldn't make any difference yet, but are committed
first so people can start testing.
