mips is removed from the binaries, so remove it from RC, too.

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.

emulators/qemu-user-static-devel: Fix build on 12 and 13

The last update broke the build on FreeBSD 12 and 13. This fixes that
with the upstreamed fix. It also moves to a slightly newer upstream
version and resolves a number of accumulated conflicts.

emulators/qemu-user-static-devel: Update with upstreaming updates

Fold in changes suggesteed by upstreaming process. Update to the latest
snapshot. It now is back to 6.0 level of functionality (so it's still
not ready to replace rebase-3.1-based qemu bsd-user), but it worth
testing.

emulators/qemu-user-static-devel: Update to latest devel version

Update to the latest pst 6.2 qemu development version for bsd-user.
This removes mips support and includes new system calls like swapoff
with two args. It's also the result of continuing efforts to upstream
changes. It's a devel version, and more dicy than most devel versions,
so caution is advised: it builds but there may be important cases that
are broken.

*/*: Remove redundant '-[0-9]*' from CONFLICTS_INSTALL

The conflict checks compare the patterns first against the package
names without version (as reported by "pkg query "%n"), then - if
there was no match - agsinst the full package names including the
version (as reported by "pkg query "%n-%v").

emulators/qemu-user-static{,-devel}: fix build on recent FreeBSD

This updates both to 6ffee39fe2e4, which pulls in some patches to fix
the build after a recent commit to main that was MFC'd to stable/13.

While we're here, update qemu-user-static-devel to point to the current
upstream. qemu-user-static-devel will likely be updated in the near
future to point to imp's 6.0 rebase branch for Q/A.

emulators/qemu-user-static: fix the build after base r368005

r368005 removed CRIOGET, breaking the qemu-user-static build. We didn't
actually implement it anyways, so this update simply ripped it out rather
than trying to maintain it for old branches.

While here, bring qemu-user-static-devel up to parity with qemu-user-static.
We should be soon approaching the point where we can rebase the former
forward to a newer qemu.

emulator/qemu-user-static: fix major regression from signal refactor

Excellent diagnosis by Andrew Gierth revealed the exact nature of the
regression from previous signal handling fixes; gobject-introspection now
builds, and we should be able to once again build a pretty large chunk of
the ports tree.

The configure script patch has been incorporated into our tree, so the patch
may be removed.

As mentioned previously, qemu-user-static and qemu-user-static-devel will
not always be updated in lockstep; future changes will land to
qemu-user-static-devel first followed by qemu-user-static.

Fix emulators/qemu-sbruno build with lld 10.0.0

As reported in bug 244251, with clang and lld 10.0.0 the emulators/qemu-sbruno
port fails in the configure stage:

===>  Configuring for qemu-user-static-2.11.50.g20191211_3

ERROR: We need to link the QEMU user mode binaries at a
       specific text address. Unfortunately your linker
       doesn't support either the -Ttext-segment option or
       printing the default linker script with --verbose.
       If you don't want the user mode binaries, pass the
       --disable-user option to configure.

qemu-user-static: revert SSP_CFLAGS workaround (ports r501032)

This was later diagnosed to be a bug in libc, which has since been addressed
in all supported releases and branches. PORTREVISION is bumped as SSP_CFLAGS
will change the output, and for consumers of these two ports it is
imperative that it be rebuilt against the updated libc to avoid high failure
rates. In testing qemu-user-static-devel failed roughly 60% of the time,
rendering it unusable as each fork/exec was yet one more chance to fail.

The bug was fixed in the following patch levels (FreeBSD-EN-20:01.ssp):
- 12.1-p2
- 12.0-p13
- 11.3-p6

emulators/qemu-user-static{,-devel}: unbreak after base r355641

r355641 added sigorset to base, which collides with sigorset in
qemu-user-static. This is effectively a patch (applied in the qemu-bsd-user
repo) that makes the qemu version private and uses that for now, until
sigorset in FreeBSD stabilizes across older branches.

NEW PORT: emulators/qemu-user-static-devel: QEMU user-mode emulation

This port represents the to-be-released version of qemu-user-static for
testing prior to unleashing it upon the community at large and the package
building infrastructure. Currently, it is based on the bsd-user-rebase-3.1
branch that moves the base qemu version of this work forward.

The main highlight of the update to 3.1 is initial riscv64 bsd-user support,
submitted by Embecosm.

This version of the port is also notably no longer based on the master port,
qemu-sbruno, but repocopied from it due to reusing a good portion of it. As
such, it's been severely reduced to eliminate all of the bits not relevant
to building bsd-user/ (including the various port options), so much of the
diff is eliminating the option-enabled checks and combining them all into a
