devel/gdb: Remove the EXPAT option.

GDB on FreeBSD requires libxml for full funtionality (e.g. 'catch
syscall <syscall name>' parses the XML files installed in
LOCALBASE/share that were still installed even when this option was
disabled).  Also, using GDB with a debug server that returns any
non-simple registers requires XML support for parsing the target
description returned by the server (e.g. examining SSE or later
registers or any system registers when attached to QEMU or
lldb-server).

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.

devel/gdb: Fix kernel backend registrations.

Per-architecture kernel backends are registered via GDB initialization
routines.  The GDB build uses a regular expression to identify the
initialization routines invoked during startup.  This regular
expression requires a single space between the function name and it's
empty argument list.  However, the initializers for aarch64, arm,
mips, and riscv had two spaces before the empty argument list causing
those backends to not be registered and the corresponding architecture
kernels to not be recognized.  Fix by removing the spurious spaces.

GDB 8.3 also adds support for FreeBSD/riscv64.

In addition, kgdb has been updated for changes in 8.3 along with
support for FreeBSD/riscv64 kernels.

The libc++ helpers have been updated to a newer version which adds
support for std::list<> and std::forward_list<>.  The helpers now

Finally, a few post-8.3 patches have been backported which add suport

powerpc, and riscv architectures.  Note that amd64 and i386 do not
support examining TLS variables in core dumps currently.  This support
along with support for additional architectures require kernel changes
and will be added in the future once the kernel has been updated.

- Backport a fix from master to fix the setting of the default

- Switch to using the default data directory (PREFIX/share/gdb)

  PREFIX/share/gdb/auto-load.  A couple of existing packages already
  do this such as libglib and libgobject.
- Add symlinks for gdb.1 and kgdb.1 manpages without version numbers.

A few more recent patches that were merged to upstream GDB:

- Handle version 1a of NT_PRPSINFO notes which include the pr_pid field.
- Replace patch-sigev with upstream version.  Note that upstream GDB
  doesn't define SIGLIBRT on older OS versions, so do that in the port
  Makefile instead.
- Use PT_GET_EVENT_MASK/PT_SET_EVENT_MASK (new in 12).
- Fix a bug where fork and LWP events weren't enabled in new child
  processes when following child processes after a fork.
- Handle "real" vfork done events via PTRACE_VFORK (new in 12).

Import several patches recently merged upstream.

- Fix fork following to honor 'detach-on-fork'
- Fix vfork following to post a fake vfork_done event to fix breakpoints
  in vfork parents (a real vfork_done event is pending but requires kernel
  changes currently in review).
- Fix x86 debug registers to work with multiple threads (PR 157755)
- Add support for 'info auxv' on both live processes and cores.
- Add support for 'catch syscall'.  Note that catching system calls by
  names requires parsing an XML file mapping system call names to
  numbers.  The port now installs the XML syscall files to the data
  directory.  In addition, the EXPAT option is now enabled by default as
  expat is used to parse the XML files.
- Bump PORTREVISION.

Make GDB build when basename() is POSIX compliant.

GDB's libiberty.h has a prototype of the basename() function it which
does not match the one that is part of POSIX, declared in libgen.h. This
is normally never visible, as GDB never includes libgen.h. On FreeBSD,
it unfortunately is, as our locally added copy of kgdb includes both.

Fix up libiberty.h to just include libgen.h. I'm currently discussing
with upstream how a clean fix should be done, but I guess that
requires more refactoring to the existing code. We'd better not bother
importing that and stick to this compact workaround.

Fix an issue with gdb triggering assertions in kgdb on i386.

The kgdb targets use runtime assertions on native targets to verify
that the helper arrays documenting the layout of things like the PCB
and trapframe structures match.  Ideally these asserts would be
compile time assertions, but they cannot be checked at compile time.
Instead, they are checked at runtime during gdb startup.

However, the layout of the i386 PCB changed when the AVX changes were
merged to i386.  The constants in the i386 target assume the post-AVX
layout, but gdb packages on stable branches might be built against
pre-AVX worlds.  In that case, those gdb binaries will trigger these
assertions on every invocation.

As a workaround, disable the PCB-related assertions on pre-AVX worlds.
If kgdb is run against a pre-AVX kernel it will not be able to parse
the PCB correctly, but userland debugging should work fine.  kgdb
built against a pre-AVX world but run against an AVX kernel should
work fine.

Various fixes to kgdb.  Port revision bumped since kgdb is enabled by
default.
- kgdb -n now permits any valid string to be used instead of only
  permitting numbers.  In particular, this allows 'kgdb -n last' to be
  used to open the most recent vmcore.
- kgdb will now try to determine the list of kernel modules even if the
  kernel binary does not include debug symbols.  This works fine in kernels
  that have the changes in r290728.
- Mark trapframes as "signal trampoline frames".  GDB assumes that "normal"
  frames will never call into a NULL PC.  Instead, it assumes that calling a
  NULL PC will result in an exception (and thus a signal being posted
  resulting in a signal frame).  A trap for a NULL function pointer would
  thus stop unwinding once it hit the frame with a NULL PC.  Marking the
  trapframes as a signal frame tells GDB it is ok to unwind past a NULL PC.
  One side effect is that frames in the asm handler now display as "signal
  handler called" instead of the raw line in assembly.  Perhaps at some
  point it would be nice to mark these up the way ddb does with the trap
  number, etc. but GDB's stack code doesn't support custom frame printers.
