When Linux loads a new kernel via kexec, somtiems it must reserve memory
for devices that are still active (and typically can't be reset or
shutdown). When present, this table is a linked list of ranges that are
still in use that the OS must avoid using.
Mark these areas as reserved.

GCC 12 raises warnings about literal operator suffixes not preceded by
'_' in libc++ headers such as <string_view> as it doesn't recognize
libc++ headers being an implementation of the standard.
GCC 12 also warns about clang-specific pragmas in <locale>.
Disabling these warnings globally for all C++ code is not ideal, but

On OpenFirmware, and possibly kboot, we use full path names for the
objects that are the 'device'. kboot uses a hack of knowing that all
disk device nodes start with '/dev', but this generalizes it for
OpenFirmware where both 'block' and 'network' devices live in the same
namespace and one must ask the OF node its type to know if this device
type matches.
For drivers that don't specify, the current convention of using
strncmp() is retained. This is done only in devparse(), but everything
uses it directly (or will soon).

To support more flexible device matching, we now pass in the full
devspec to the parsedev routines. For everything execpt uboot, this is
just a drop in (since everything except uboot and openfirmware always
uses disk...: and/or zfs:, but openfirmware isn't really affected).
uboot we kludge around it by subtracting 4 from where the rest of the
device name starts. This is unforunate, and can compute the address one
before the string. But we never dereference that address. uboot needs
more work, and this is an acceptable UB until that other work happens.
OFW doesn't really use the parsedev routines these days (since none of
the supported device uses this... yet). It too needs more work, but it
needs device matching support first.

The rest of the code in the tree assumes that a DEVT_DISK uses a
disk_devdesc to represent the device. However ofw_disk diesn't, so we
can't use disk_fmtdev, nor disk_parsedev. ofw needs to have a
dv_match-like routine to use devpasrse, though, since we have two
drivers (net and block) that claim the same sort of devices (eg
/path/to/ofw-dev) based on the device-type property. In the interim, we
can't use devmatch and ofw_disk's and the default net driver's parsing
is offloaded ofw_parsedev.

Allow device classes to define a parsing routine. Most device classes
already have these routines, but there's much duplication in their
use. Define an interface for a common routine to parse an individual
device. By convetion, files have the form "[device:]/path/to/file"
where device is optional (filled in to be the value of currdev)
and it starts with the dv_name field of the device, with the rest
of the name up to the device (typically a unit number, but disks
add partition inforation, and other devices may do artibtrary
otehr things).

Netlink has a confirmation/error reporting mechanism for the sent
messages. Kernel explicitly acks each messages if requested (NLM_F_ACK)
or if message processing results in an error.
Similarly, for multipart messages - typically dumps, where each message
represents a single object like an interface or a route - another
message, NLMSG_DONE is used to indicate the end of dump and the
resulting status.
As a result, successfull dump ends with both NLMSG_DONE and NLMSG_ERROR
messages.
RFC 3549 does not say anything specific about such case.
Linux adopted an optimisation which suppresses NLMSG_ERROR message
when NLMSG_DONE is already sent. Certain libraries/applications like
libnl depends on such behavior.
Suppress sending NLMSG_ERROR if NLMSG_DONE is already sent, by
setting newly-added 'suppress_ack' flag in the writer and checking
this flag when generating ack.
This change restores libnl compatibility.
