FICL definitions not in ficl/ficl32 files broke this generally. This
makes that stuff conditional on BOOT_FORTH. Also, move definitions
related to the architecture (FICL_CPUARCH and friends) into
Makefile.ficl that all parts of the tree that include files with ficl
need to include (but only if MK_FORTH == yes). In addition, had to fix
library ordering issue with LIBSTAND to keep it last. Without boot
forth, there's no references to memset to bring in memset.o from
libstand.a to satisfy libgeliboot.a's use of it. Listing libstand last
solves this issue (and it's the proper place for libstand to boot).

To achieve that the whole svm_softc is allocated with contigmalloc now.
It would be more effient to de-embed those arrays and allocate only them
with contigmalloc.
Previously, if malloc(9) used non-contiguous pages for the arrays, then
random bits in physical pages next to the first page would be used to
determine permissions for I/O port and MSR accesses. That could result
in a guest dangerously modifying the host hardware configuration.
One example is that sometimes NMI watchdog driver in a Linux guest
would be able to configure a performance counter on a host system.
The counter would generate an interrupt and if hwpmc(4) driver is loaded
on the host, then the interrupt would be delivered as an NMI.

loss event but not use or obay the recommendations i.e. values set by it in some
cases.
Here is an attempt to solve that confusion by following relevant RFCs/drafts.
Stack only sets congestion window/slow start threshold values when there is no
CC module availalbe to take that action. All CC modules are inspected and
updated when needed to take appropriate action on loss.
tcp_stacks/fastpath module has been updated to adapt these changes.
Note: Probably, the most significant change would be to not bring congestion
window down to 1MSS on a loss signaled by 3-duplicate acks and letting
respective CC decide that value.

when the new/default NFS server was running, for the "-n" option.
This patch fixes the problem for head and stable/11. For stable/10 the
patch will need to be modified when MFC'd, since the stable/10 mountd.c
handles both old and new NFS servers.
Since the new NFS server uses vfs.nfsd.nfs_privport == 0 by default,
there wouldn't have been many users affected by the code not setting
it to 0 when the "-n" option was specified.

In r304435, ip_output() was changed to use the result of the route
lookup to decide whether the outgoing packet was a broadcast or
not. This introduced a regression on interfaces where
IFF_BROADCAST was not set (e.g. point-to-point links), as the
algorithm could incorrectly treat the destination address as a
broadcast address, and ip_output() would subsequently drop the
packet as broadcasting on a non-IFF_BROADCAST interface is not
allowed.

- Simplify interface to nmi_handle_intr() by evaluating panic_on_nmi
in one place, namely nmi_call_kdb(). This allows to remove do_panic
argument from the functions, and to remove i386/amd64 duplication of
the variable and sysctl definitions. Note that now NMI causes
panic(9) instead of trap_fatal() reporting and then panic(9),
consistently for NMIs delivered while CPU operated in ring 0 and 3.
