lib/msun: Added fmaximum_mag and fmaximum_num families
Added support for the f{maximum,minimum}_{mag,num} families, the new
C23 standard functions for maximum magnitude and number-preferring
maximum. This includes modifying fmax.3, on top of D56230, to
recommend the use of fmaximum_num and fminimum_num.

lib/msun: Added fmaximum and fminimum family. Tests and man page
Starting from the existing fmax{,f,l} functions I've added the fmaximum
family, which handles NaN according to the newest standard (propagating
it).

boot1.chrp: Specify --image-base
This is required for LLVM 22's ld.lld to avoid a build error:
ld.lld: error: section '.text' address (0x38000) is smaller than image base (0x10000000); specify --image-base
ld.lld: error: section '.rodata' address (0x3b308) is smaller than image base (0x10000000); specify --image-base

Use 0x38000 for the image base, which is the address of the lowest

libifconfig: Skip bridge VLAN config for span members
bridge(4) doesn't support BRDGGIFVLANSET for span members, which
means if a span interface is configured, libifconfig will fail to

nfsd: Disable use of callbacks for NFSv4.0
Commit 71ac1ec5c9d9 disabled callbacks for the NFS
client for NFSv4.0. This patch does the same for
the NFSv4.0 server.
The only use for callbacks for NFSv4.0 is delegations
and delegations rarely work well for NFSv4.0 anyhow.
Therefore, this patch disables callbacks for the
NFSv4.0 server. This is the same behavior as
occurs when vfs.nfsd.issue_delegations is 0.
This change allowed the functions called
nfsrv_getclientipaddr() and nfsrv_getipnumber() to be
removed from the kernel.

tests: Add some simple regression tests for ip_mroute
These use atf_python to create a number of hosts linked to a router.
The router runs pimd (for IPv4) or ip6_mrouter (simplistic IPv6
multicast router that I wrote since I couldn't find one in the ports
tree). The vnet_host*_handler() methods are invoked in different VNET
jails connected to the router; they register the connected epair with a
multicast group and verify that they can send messages to each other.
The tests are synchronized by sending messages over a unix domain
socket. The flow is something like:
1) test startup_method() is called, the unix socket is created,
2) the superclass creates jails and links them together using the
declared topology,
3) we wait for all child jails to start up and send a message on the
unix socket indicating that they are ready
4) we start the routing daemon in the main jail,
5) the test actually starts; starttest() kicks off the
vnet_host*_handlers(), which mostly just verify that they can send

ip_mroute: Fix a lock leak in X_ip_mforward()
If a FIB does not have a router configured, X_ip_mforward() would leak a
lock. Plug the leak.
The IPv6 counterpart did not have such a check. It wouldn't send an
upcall to a non-existent router anyway due to the router_ver check, but
we should verify that a router is present anyway.
Add regression test cases to exercise these code paths.

ip6_mroute: Handle interface detach events
When an interface goes away we need to make sure the v6 multicast
routing tables don't carry any dangling references to the ifnet. The v4
code handles this already. Copy the approach there and use an
eventhandler to purge the corresponding MIF, if one exists, and further
go through all routes in the FIB and remove references to the interface.

Fix nooptions VIMAGE build
The recent FIBify commits deref struct thread without including
sys/proc.h, which can result in a compiler error. This becomes
apparent when building with LINT-NOVIMAGE, as net/vnet.h includes
