*/*: use USES=sbrk

Replace various BROKEN entries for missing sbrk on aarch64 and risc64
with USES=sbrk.

Fix a few missing entries (generally ports blocked by other
dependences).

This is broken due to a new compiler on 14 so presumably also on 15.

shells/ksh: Remove the now expired ksh2020 from CONFLICTS.

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.

Approved by:		portmgr (tcberner)

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 redundant '-*' from CONFLICTS definitions

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").

One more small cleanup, forgotten yesterday.

Remove # $FreeBSD$ from Makefiles.

For ports on riscv64 that fail the same (or similar ways) to aarch64, mark
them BROKEN.

Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.

Resurrect the previous shells/ksh93 as  shells/ast-ksh, a ksh93 port
that the maintainer wishes to use to create a shared library for use
with other applications such as CDE. It is based on ksh93v (2014-12-24)
and is incompatible with the direction that att/ast is taking the
official ksh93 implementation.
