of these structures across the kernel.  This will make it
easier to change the implementation of these statistics,

In on case, icmp6stat members are manipulated indirectly, by
icmp6_errcount(), and this will require further work to fix
for per-CPU stats.

e2421f7667 Merge from libarchive.googlecode.com: Mostly a bunch of
corrections to the Windows support to reconcile differences
between Visual Studio and Cygwin.  Includes parts of
revisions 757, 774, 787, 815, 817, 819, 820, 844, and 886.

Of particular note, r886 overhauled the UTF-8/Unicode conversions to
work correctly regardless of whether the local system uses 16-bit
or 32-bit wchar_t.  (I assume that systems with 16-bit wchar_t
use UTF-16 and those with 32-bit wchar_t use UCS-4.)  This revision
also added a preference for wcrtomb() (which is thread-safe) on
platforms that support it.

ab5378cf11 Previously, when vm_page_free_toq() was performed on a page belonging to
a reservation, unless all of the reservation's pages were free, the
reservation was moved to the head of the partially-populated reservations
queue, where it would be the next reservation to be broken in case the
free page queues were emptied.  Now, instead, I am moving it to the tail.
Very likely this reservation is in the process of being freed in its
entirety, so placing it at the tail of the queue makes it more likely that
the underlying physical memory will be returned to the free page queues as
one contiguous chunk.  If a reservation must be broken, it will, instead,
be the longest unchanged reservation, which is arguably the reservation
that is least likely to ever achieve promotion or be freed in its entirety.

bfe1aba468 Introduce vnet module registration / initialization framework with
dependency tracking and ordering enforcement.

With this change, per-vnet initialization functions introduced with
r190787 are no longer directly called from traditional initialization
functions (which cc in most cases inlined to pre-r190787 code), but are
instead registered via the vnet framework first, and are invoked only
after all prerequisite modules have been initialized.  In the long run,
this framework should allow us to both initialize and dismantle
multiple vnet instances in a correct order.

The problem this change aims to solve is how to replay the
initialization sequence of various network stack components, which
have been traditionally triggered via different mechanisms (SYSINIT,
protosw).  Note that this initialization sequence was and still can be
subtly different depending on whether certain pieces of code have been
statically compiled into the kernel, loaded as modules by boot
loader, or kldloaded at run time.

The approach is simple - we record the initialization sequence
established by the traditional mechanisms whenever vnet_mod_register()
is called for a particular vnet module.  The vnet_mod_register_multi()
variant allows a single initializer function to be registered multiple
times but with different arguments - currently this is only used in
kern/uipc_domain.c by net_add_domain() with different struct domain *
as arguments, which allows for protosw-registered initialization
routines to be invoked in a correct order by the new vnet
initialization framework.

For the purpose of identifying vnet modules, each vnet module has to
have a unique ID, which is statically assigned in sys/vimage.h.
Dynamic assignment of vnet module IDs is not supported yet.

A vnet module may specify a single prerequisite module at registration
time by filling in the vmi_dependson field of its vnet_modinfo struct
with the ID of the module it depends on.  Unless specified otherwise,
all vnet modules depend on VNET_MOD_NET (container for ifnet list head,
rt_tables etc.), which thus has to and will always be initialized
first.  The framework will panic if it detects any unresolved
dependencies before completing system initialization.  Detection of
unresolved dependencies for vnet modules registered after boot
(kldloaded modules) is not provided.

Note that the fact that each module can specify only a single
prerequisite may become problematic in the long run.  In particular,
INET6 depends on INET being already instantiated, due to TCP / UDP
structures residing in INET container.  IPSEC also depends on INET,
which will in turn additionally complicate making INET6-only kernel
configs a reality.

The entire registration framework can be compiled out by turning on the
VIMAGE_GLOBALS kernel config option.

e89da24b3d Two refinements to the 3c1 support:
1) Flag it and only access that command on the 3c1
2) The TX PLL appears to power down when not in use, so we have to power
   it back up when we've been idle.  Do this at the start of ifstart.
   Otherwise we fall off the net.

  could be had by managing this better, but for now it gets my card
