pciconf: Add option to write into a BAR region
Add option -W that allows to write into a BAR region.
Also, add an option -R that allows to read from a BAR region that
works similar to -r that reads from the PCI config space.

OFED: Various changes from Linux 4.19
Many of these changes deal with shifting from fetcing SGID attributes
via an index in drivers to including references to SGID attributes in
other structures passed to driver callbacks which can be used directly
avoiding the need for fetching attributes via lookup functions. I had
to fixup the ROCE GID management code directly as the version in
FreeBSD is very different from Linux.
I also tweaked the change from commit
475c8de7bf2dc86d9806709a04e9c8f524d4ec32 to use a goto to reduce diffs
with upstream to minimize conflicts when merging upstream changes.

OFED: Various changes from Linux 4.12
Most of the changes involve renaming InfiBand address handles (AH) to
RDMA address handles including renaming various types and functions.
Address handles now also include type-specific fields and a set of
wrapper accessor functions for getting and setting fields. For some
of the type and function renames, drivers in sys/dev had to be updated
directly (typically via sed).

jail: call PR_METHOD_ATTACH again (with old jail) if the first call fails
jail_attach lets modules do attachment-specific work by calling
osd_jail_call(PR_METHOD_ATTACH). If one of the modules returns an
error, the call needs to be repeated with the thread's current prison,
so possible earlier modules and undo any changes they may have made.

libcxxrt: Fix diagnostics for derived classes
In terminate_with_diagnostics the cast_to arguments were swapped, so it
always failed. The diagnostic handler produced output like "Terminating
due to uncaught exception 0x24891e08000 of type std::runtime_error".
Now, e->what() will actually be included in the output, e.g.
"Terminating due to uncaught exception 0x2bba49208000 'Model file
doesn't exist' of type std::runtime_error".

The amdgpu DRM driver used it at some point in the development cycle of
Linux 6.14 but the use case was dropped later. Let's still add it to
