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 # $FreeBSD$ from Makefiles.

Fix build with src r354909 applied.

The referenced change made NO_INSTALLLIB, NO_MAN, and NO_PROFILE into
errors causing these ports that declare them and use the FreeBSD make
infrastructure as part of their build to fail.

When the offending variables occur in a BSD Makefile, NO_MAN becomes
MAN= and NO_INSTALLLIB and NO_PROFILE become MK_INSTALLLIB=no and
MK_PROFILE=no respectively.  When declared in the environment they
become WITHOUT_<FOO>.

Release some of my ports back to the heap

databases/libnvpair: Limit to amd64 and i386

The ARMv6, mips, and mips64 builds are all failing on the isa.defs.h
support check and there's no ETA for a support fix.

- Add USES=uidfix to fix staging as non-root
- Add USE_LDCONFIG as the port installs shared library

databases/libnvpair: New major version (so.1 => so.3)

The changes since version 1.0.2 were significant enough to warrant
a major library version bump.  However, libnvpair.so.2 exists in
FreeBSD base, so the port version builds libnvpair.so.3 instead.

With one exception, all of the Solaris/Illumos types have been
replaced with BSD equivalents, including boolean_t.  This changes
several prototypes, and also allows for the type compatibility header
to be removed.  The one type that remains is hrtime_t (equivalent to
int64_t).

Internally, the regression tests for print_json (functionality that
does not exist in FreeBSD base, at least on F9) have been added from
Illumos regression tests and both DragonFly and FreeBSD pass.

Add new port databases/libnvpair

libnvpair is a name-value pair library originating from Solaris

The nvpair library was released in OpenSolaris and has been extended
by the Illumos project.  It exports a set of functions used for managing
name-value pairs.  This is a base library for Solaris and its descendents.
However, the kernel-specific code has been removed thus libnvpair is
strictly meant for the userland.  The XDR functionality has been masked
for now due to RPC differences between *BSD and Illumos.
