Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

Remove latest references to USE_BISON

Convert USE_BISON to USES= bison

It brings bison as a build dependency in case it is set the following way:
USES= bison or USES= bison:build

it brings bison as a run dependency in case it is set the following way:
USES= bison:run

it brings bison both as a run and build dependency in case it the set the
following way:
USES= bison:both

While here trim some headers
Convert some USE_GNOME= gnomehack to USES= pathfix

Update CONFIGURE_ARGS for how we pass CONFIGURE_TARGET to configure script.
Specifically, newer autoconf (> 2.13) has different semantic of the
configure target. In short, one should use --build=CONFIGURE_TARGET
instead of CONFIGURE_TARGET directly. Otherwise, you will get a warning
and the old semantic may be removed in later autoconf releases.

To workaround this issue, many ports hack the CONFIGURE_TARGET variable
so that it contains the ``--build='' prefix.

To solve this issue, under the fact that some ports still have
configure script generated by the old autoconf, we use runtime detection
in the do-configure target so that the proper argument can be used.

New port: mail/libsieve A library to interpret Sieve scripts, and
to execute them over a given set of messages

    A library for parsing, sorting and filtering your mail.  libSieve
    provides a library to interpret Sieve scripts, and to execute
    those scripts over a given set of messages. The return codes
    from the libSieve functions let your program know how to handle
    the message, and then it's up to you to make it so. libSieve
    makes no attempt to have knowledge of how SMTP, IMAP, or anything
    else work; just how to parse and deal with a buffer full of
    emails.
