rtw89: add man page and hook driver up to the build

After two years, add the initial man page and hook Realteks rtw89
driver up to the build for more people to test given successful
reports.
devd.conf is already providing support based on the rtw<n+> regex.
The driver uses the LinuxKPI compat layer.

Firmware is provided by ports: net/wifi-firmware-rtw89-kmod or
one of the flavours. People are advised to used fwget(8) to
automatically install the correct firmware for their chipset.

Please note that for the moment the driver requires a tunable to
be set in loader.conf: compat.linuxkpi.skb.mem_limit=1

Many thanks to everyone who in the last two years helped testing,
debugged, submitted patches to get the driver to this stage where
initial functionality seems working.

mac_do: add a new MAC/do policy and mdo(1) utility

This policy enables a user to become another user without having to be
root (hence no setuid binary). it is configured via rules using sysctl
security.mac.do.rules

For example:
security.mac.do.rules=uid=1001:80,gid=0:any

The above rule means the user identifier by the uid 1001 is able to
become user 80
Any user of the group 0 are allowed to become any user on the system.

The mdo(1) utility expects the MAC/do policy to be installed and its
rules defined.

snd_hdsp(4): RME HDSP 9632 and HDSP 9652 sound card driver.

Add a sound(4) bridge device driver for the RME HDSP 9632 and HDSP 9652
sound cards. These cards require a nowadays rare PCI 32bit (not PCIe)
slot, but still see use due to their value and wealth of features.
The HDSP 9632 is mostly comparable to the newer HDSPe AIO, while the
HDSP 9652 is similar to the HDSPe RayDAT. These HDSPe PCIe cards are
supported by the snd_hdspe(4) driver which was taken as a starting point
for development of snd_hdsp(4).

Implementation is kept separately due to substantial differences in
hardware configuration and to allow easy removal in case PCI 32bit
support would be phased out in the future.

The snd_hdsp(4) kernel module is not enabled by default, and can be
loaded at runtime with kldload(8) or during boot via loader.conf(5).
Basic operation was tested with both cards, not including all optional
cable connectors and expansion boards. Features should be roughly on par
with the snd_hdspe(4) supported cards.

nvmft: The in-kernel NVMe over Fabrics controller

This is the server (target in SCSI terms) for NVMe over Fabrics.
Userland is responsible for accepting a new queue pair and receiving
the initial Connect command before handing the queue pair off via an
ioctl to this CTL frontend.

This frontend exposes CTL LUNs as NVMe namespaces to remote hosts.
Users can ask LUNS to CTL that can be shared via either iSCSI or
NVMeoF.

nvmf: The in-kernel NVMe over Fabrics host

This is the client (initiator in SCSI terms) for NVMe over Fabrics.
Userland is responsible for creating a set of queue pairs and then
handing them off via an ioctl to this driver, e.g. via the 'connect'
command from nvmecontrol(8). An nvmeX new-bus device is created
at the top-level to represent the remote controller similar to PCI
nvmeX devices for PCI-express controllers.

As with nvme(4), namespace devices named /dev/nvmeXnsY are created and
pass through commands can be submitted to either the namespace devices
or the controller device. For example, 'nvmecontrol identify nvmeX'
works for a remote Fabrics controller the same as for a PCI-express
controller.

nvmf exports remote namespaces via nda(4) devices using the new NVMF
CAM transport. nvmf does not support nvd(4), only nda(4).

nvmf_tcp: Add a TCP transport for NVMe over Fabrics

Structurally this is very similar to the TCP transport for iSCSI
(icl_soft.c). One key difference is that NVMeoF transports use a more
abstract interface working with NVMe commands rather than transport
PDUs. Thus, the data transfer for a given command is managed entirely
in the transport backend.

Similar to icl_soft.c, separate kthreads are used to handle transmit
and receive for each queue pair. On the transmit side, when a capsule
is transmitted by an upper layer, it is placed on a queue for
processing by the transmit thread. The transmit thread converts
command response capsules into suitable TCP PDUs where each PDU is
described by an mbuf chain that is then queued to the backing socket's
send buffer. Command capsules can embed data along with the NVMe
command.

On the receive side, a socket upcall notifies the receive kthread when
more data arrives. Once enough data has arrived for a PDU, the PDU is
handled synchronously in the kthread. PDUs such as R2T or data
related PDUs are handled internally, with callbacks invoked if a data
transfer encounters an error, or once the data transfer has completed.
Received capsule PDUs invoke the upper layer's capsule_received
callback.

struct nvmf_tcp_command_buffer manages a TCP command buffer for data
transfers that do not use in-capsule-data as described in the NVMeoF
spec. Data related PDUs such as R2T, C2H, and H2C are associated with
a command buffer except in the case of the send_controller_data
transport method which simply constructs one or more C2H PDUs from the
caller's mbuf chain.
