devel/rust-cxxbridge: New port
cxxbridge generates the C++ side of the cxx bridge and is required
at build time by projects that use corrosion's
corrosion_add_cxxbridge() without network access.
stress2: add two new unionfs test scenarios
These exercise lookup traversal from tmpfs into unionfs, which is
useful because, unlike UFS, tmpfs does not allow recursion on its vnode
locks by default.
unionfs22.sh exercises these lookups with a normal unionfs mount, while
unionfs23.sh uses '-o below' for the unionfs mount and reproduces the
panic described in PR 298201.

vfs_lookup_cross_mount(): fix missing LK_CANRECURSE
This was a rather dumb miss on my part in commit 42442d7a6e.
LK_CANRECURSE is clearly needed in any case in which the covered vnode
is held exclusive across the call to VFS_ROOT(), regardless of whether
it was initially held exclusive or upgraded. The commit message for
that change also noted that unionfs lookup only worked without
LK_CANRECURSE due to a coincidence of the then-current unionfs
implementation. As it happens, said coincidence was recently removed
in commit b952606b4f ("unionfs_lock(): eliminate LK_CANRECURSE special-
case").

iwx: fix kernel panic on module unload with assertions enabled
When interface is up and running 'kldunload if_iwx' stops the device and executes RUN -> INIT state transition.
Since the device is already stopped iwx_run_stop fails to stop the device again and returns non-zero exit code from iv_newstate callback which triggers 'INIT state change failed' assertion.
I reused IWX_FLAG_SHUTDOWN flag to:
a) set it in iwx_detach
b) check it in iwx_newstate_sub - when it is set all custom state transition logic is skipped
Accidentally found while experimenting with iwlwifi / iwx drivers

[ELF,test] Cover wildcard precedence in version scripts and dynamic lists (#223195)
version-script-wildcard-precedence.s, renamed from
version-script-reassign-glob.s, covers more cases.
dynamic-list-glob.s absorbs dynamic-list-cpp.s and adds an extern "C++"
wildcard, which had no --dynamic-list coverage.
pci: Adapt PME capability queries to stable/14
Add explicit D3hot and D3cold names and the bounds needed by
pci_has_pme(), while retaining PCI_POWERSTATE_D3 == 3. D3cold is a
capability-query state here, not a newly supported power transition.
This avoids importing the ACPI D3cold changes for the PME and igc
Wake-on-LAN backports.
Use pci_has_pm() to check capability presence instead of pp_location,
which is not present in stable/14. Keep the PCI configuration structure
layout unchanged.

igc: Correct Wake-on-LAN filter programming
The attach path translated WUC.APME into a saved link-change filter,
then advertised magic-packet wake. Suspend removed unselected magic,
unicast, and multicast bits from that saved value, commonly leaving no
hardware wake filter at all. The destructive masking also made later
capability changes ineffective.
Advertise the I225/I226 wake filters whenever PCI power management is
available and enable magic-packet wake by default. Build a fresh WUFC
mask for every suspend, and explicitly clear WUC, WUFC, and PCI PME when
wake is disabled.
Require the PCI power-management capability to report D3hot PME support
before advertising or arming wake. A PM capability alone does not mean
the function can signal PME from the state used during system sleep.
Reconstruct RAR0, the multicast table, and the receive filter after the
stop-time reset so unicast and multicast wake use the current interface
