devel/gdb: Update to 12.1.

One notable feature included in 12.1 is async target support
permitting the use of commands like continue&.

In addition, this commit backports various post-12 commits to add
support for hardware breakpoints/watchpoints on aarch64, support for
resolving TLS variables from core dumps on amd64 and i386 via the
recently added NT_X86_SEGBASES core dump note, and support for
resolving TLS variables on arm and aarch64 via the recently added
NT_ARM_TLS register set.

Update to GDB 9.1.

GDB 9 rejects attempts to build in the source tree, so this uses
CONFIGURE_OUTSOURCE.

Some patch files were renamed to track moving of files in upstream.

Update port to GDB 8.3.

New features in GDB 8.3 include support for DWARF index caches and
styling (colors) in the CLI and TUI.  Source code styling is also
available via the new SOURCE_HIGHLIGHT option (enabled by default).
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
also support Python 3.

Finally, a few post-8.3 patches have been backported which add suport
for TLS (Thread Local Storage) variables on FreeBSD amd64, i386,
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.

KGDB fixes for amd64 and aarch64.

- Update the amd64 kernel support to recognize mchk_calltrap as a
  trapframe generator.
- Remove some unneeded headers from fbsd-kld.c.
- Various fixes to get stack traces working for aarch64 kernels:
  - Map the LR register from the PCB to PC instead of LR.
  - Skip the PC register from the PCB as it isn't initialized to anything.
  - Correct the register cache map for the PCB.  The old one had the
    offsets of pcb_sp and pcb_pc reversed.
  - Don't map all of the saved general purpose registers in a
    trapframe to X1 rather than X0 .. X29.
  - Use correct name for el0 trapframe entry points.

Upgrade to GDB 8.0.

- Commit b5430a3ced fixes parsing of 32-bit MIPS process cores.
- kgdb has been ported to 8.0 including renaming the new OSABI constant,
  using gdb_bfd_openr, new return type of ldirname, and solib_add
  changed.
- GDB 8.0 requires C++11, however the port is marked as requiring C++14
  as a workaround for bugs in clang 10.3.
- patch-armfbsd is updated for the new OSABI constant names (a.out was
  removed in 8.0) and new filename convention (arm-fbsd-*)
- patch-gdb-amd64-bsd-nat.c (renamed from patch-gdbamd64-bsd-nat.c) is
  simplified to just store the r_flags value before collecting registers
  from the register cache rather than a full copy of the entire register
  set.
- patch-gdb-corelow.c has been removed.  It isn't really correct and if
  arm cores still cause core dumps the error is in arm-fbsd-tdep.c.
- patch-gdb-i386-fbsd-nat.c renamed to account for rename of patched
  file.
- patch-gdb-x86bsd-nat.c has been removed.  The file was renamed, but the
  stock file also compiled fine for me on i386.

Fix several issues with kgdb:

- The kld parsing code in kgdb was using basename() and dirname() which
  ended up being broken by the recent changes to make dirname() modify its
  input buffer.  Modify fbsd-kld.c to use the lbasename() and ldirname()
  wrappers in gdb.
- Add the kgdb.1 manpage from base and install it as 'kgdbNNN.1' which is
  helpful since stock HEAD no longer ships a kgdb manpage.
- Link libkvm into mips binaries so that the vmcore target links.
- Bump PORTREVISION.

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.

Add a new KGDB option to the devel/gdb port.  This adds a forward port
of the kernel-specific bits of kgdb to recent gdb.  It only supports
amd64, i386, powerpc, powerpc64, and sparc64.
