- remove HT_HEADER test (MT_HEADER == MT_DATA for some time now)
- be more pedantic about m_nextpkt in other than first mbuf
- update m_flags to be retained
- shrink size guards for vnet_net.
vnet_rtable does not need size guards as it is self-contained.
- remove a bunch of defines from vnet.h no longer valid.
Vimage module, which had been there already but now is stateful.
All variables are now file local; so this further limits the global
spreading of routing related things throughout the kernel.
Add a missing function local variable in case of MPATHing.

No longer export rt_tables as all lookups go through
rt_tables_get_rnh().
We cannot make rt_tables (and rtstat, rttrash[1]) static as
netstat -r (-rs[1]) would stop working on a stripped
VIMAGE_GLOBALS kernel.

int. All of its callers pass in cmd as a u_long, so this has
always been a dangerous type demotion. It was spooted by clang/llvm

a pointer to an ifaddr matching the passed socket address, returns a
boolean indicating whether one was present. In the (near) future,
ifa_ifwithaddr() will return a referenced ifaddr rather than a raw
ifaddr pointer, and the new wrapper will allow callers that care only
about the boolean condition to avoid having to free that reference.

address lists, at_ifaddr_list. Acquire the lock, and use ifaddr
refcounts where necessary, to close most known address-related
races in netatalk.
Annotate one potential race in at_control() where we acquire an
ifaddr reference, drop the global lock, and scrub the address from
the ifnet before re-acquiring the global lock, which could allow
for a writer-writer race.

remaining potential races in ifconfig's management of IPX addresses.
This is largely accomplished by dropping a global write lock for the
IPX address list over the body of in_control(), although there are
some places we bump the refcount on an ifaddr of interest while
calling out to the routing code or link layer code, which might
require revisiting.
Annotate one as a potential race if two simultaneous delete ioctls
are issued for the same IPX addresses at once.

calls to vdrop() until after the free page queues lock is released. This

- Unify reference count and lock initialization in a single function,
ifa_init().
- Move tear-down from a macro (IFAFREE) to a function ifa_free().
- Move reference count bump from a macro (IFAREF) to a function ifa_ref().
- Instead of using a u_int protected by a mutex to refcount(9) for
reference count management.
The ifa_mtx is now used for exactly one ioctl, and possibly should be
removed.

vn_open_cred in default implementation. Valid struct ucred is needed for
audit and MAC, and curthread credentials may be wrong.
This further requires modifying the interface of vn_fullpath(9), but it
is out of scope of this change.

vn_open_cred invocations shall not audit namei path.
In particular, specify VN_OPEN_NOAUDIT for dotdot lookup performed by
default implementation of vop_vptocnp, and for the open done for core
file. vn_fullpath is called from the audit code, and vn_open there need
to disable audit to avoid infinite recursion. Core file is created on
return to user mode, that, in particular, happens during syscall return.
The creation of the core file is audited by direct calls, and we do not
want to overwrite audit information for syscall.
