umb: Introduce the USB umb(4) network driver
This includes the port of a driver originally from OpenBSD, later
ported to NetBSD by the author:
* The umb(4) kernel driver
* The umbctl(8) companion tool
This driver supports USB network devices implementing the
Mobile Broadband Interface Model (MBIM), often found in modern
(internal) USB models for 4G/LTE mobile broadband access.
It is currently limited to IPv4.
umbctl has to be used to display or set MBIM cellular modem
interface parameters (4G/LTE).

sys: add MBM device ioctl() values
This is part of the upcoming USB umb(4) work. It implements the control

ktrace: Fix uninitialized memory disclosure
The sockaddr passed to ktrcapfail() may be smaller than
sizeof(struct sockaddr), and the trailing bytes in the sockaddr
structure will be uninitialized, whereupon they get copied out to
userspace.

nfsd: Add support for the NFSv4.2 change_attr_type attribute
Richard Kojedzinszky reported an intermittent problem where
the Linux NFSv4.2 client would sometimes not see changes done
to a directory by another client, although the change attribute
for the directory had changed.
A test patch that added the change_attr_type attribute to the
server and always returned NFS4_CHANGE_TYPE_VERSION_COUNTER_NOPNFS
seems to have resolved the issue. Somewhat oddly, the Linux
knfsd server does not support this attribute but does not
seem to exhibit the stale caching problem.
This patch uses the VFCF_FILEREVINC flag on a file system (UFS, ZFS)
to return NFS4_CHANGE_TYPE_VERSION_COUNTER_NOPNFS. It also
returns NFS4_CHANGE_TYPE_TIME_METADATA if VFCF_FILEREVCT is set,
which may be useful for exported fuse file systems.

netlink: provide snl_clone() to create a secondary snl state
The function will clone an existing snl_state(). The clone points at the
same socket, but has a separate allocator. Closing a clone frees the
memory, but doesn't close the socket. Such clones are handy in a
multithreaded process that has a single socket with multiple writers and a
serialized reader. It can be easily extended to support multiple readers,
too, but now there is no use.

libsecureboot add sha384 and sha512 for OpenPGP
gpg supports SHA384, SHA512 as well as SHA256 so allow for them.
Tweak Makefile.inc so we can build libsecureboot with only OpenPGP
trust anchors.

netlink: underscore snl_get_genl_family_info() to discourage its use
This function uses already supposedly opaque struct _getfamily_attrs as
the argument and it fills it with pointers to volatile memory, which makes
it is unsafe for general use. While here also underscore structures that
hang off the struct _getfamily_attrs.
Small programs like powerd(8) and RPC daemons are converted to use
snl_get_genl_mcast_group() and/or snl_get_genl_family(). The genl(1)
utility was fixed not to mix its own parsers with parsers declared in
netlink_snl_generic.h.

netlink: provide snl(3) API for variable length raw data attribute
Rename supposedly internal _snl_reserve_msg_attr() into an official

nlattr followed by allocated memory. Adjust the snl_reserve_msg_attr()
macro to work on top of that function.

vtfontcvt: Improve error message for unsupported DWIDTH
vtfontcvt requires that all glyphs are 1x or 2x a common width,
reporting for example "bitmap with unsupported DWIDTH 27 0 on line xxx"
if the font is expected to be 32 pixels wide.
Add the expected / permitted values to the error message to make the
issue more clear - for the same example,
"bitmap with unsupported DWIDTH 27 0 (not 32 or 64)".
