Enter the net epoch when traversing a list of interfaces. For that
split the ifname_linux_to_bsd() function on two counterparts, where
the ifname_linux_to_ifp() intended to use in epoch, while the
ifname_linux_to_bsd() intended to be a self-contained.
Until the linux_ioctl_coket() function is refactored, the
ifname_linux_to_bsd() temporarily returns interface outside
of the net epoch.

To run mountd in a vnet prison, three checks in vfs_domount()
and vfs_domount_update() related to doing exports needed
to be changed, so that a file system visible within the
prison but mounted outside the prison can be exported.
I did all three in a minimal way, only changing the checks for
the specific case of a process (typically mountd) doing exports
within a vnet prison and not updating the mount point in other
ways. The changes are:
- Ignore the error return from vfs_suser(), since the file
system being mounted outside the prison will cause it to fail.
- Use the priv_check(PRIV_NFS_DAEMON) for this specific case
within a prison.
- Skip the call to VFS_MOUNT(), since it will return an error,
due to the "from" argument not being set correctly. VFS_MOUNT()
does not appear to do anything for the case of doing exports only.

Without this patch, a single initialization function was
used to initialize both the vnet'd and non-vnet'd data.
This patch separates out the non-vnet'd initializations
into a separate function invoked by SYSINIT().
This avoids use of IS_DEFAULT_VNET() in the initialization
functions and also configures the non-vnet'd initialization
function to be called first, although ordering is not
currently needed.

The "canonical" EBR partition names like `ada0s4+00002081` are not
particularly meaningful. The "compat" aliases share the same namespace
as the parent MBR, resulting in user-friendly names like `ada0s6`.
These names are consistent with the way Linux names EBR partitions.
We previously provided a sysctl kern.features.geom_part_ebr_compat
(enabled by default) to control the "compat" names. Remove the sysctl
and always create the aliases.

ACPI is not handled specially by sys/conf/kern.opts.mk (unlike a few
options), so we should fall back on the generic behavior of
sys/conf/config.mk, which pulls from all the generated opt*.h files,
including opt_acpi.h, which will cause DEV_ACPI to be included in
KERN_OPTS. Then the generic machinery in sys/conf/kmod.mk will cause
SRCS.DEV_ACPI to be included in SRCS when appropriate.

Mapping the framebuffer with WC (Write Combined) memory type can, in
practice, cause some memory transactions to be rate-limited at a
fraction of the fb write rate. WC allows one core to queue up many
globally visible write transactions, and in the process some unrelated
transactions may end up having to wait for all of the queued up PCI
writes to be flushed.
Add an hw.efifb.cache_attr tunable to allow mapping the framebuffer as
uncacheable instead. We should likely be taking a more careful approach
of checking the memory map to determine which cacheability attributes
are feasible, but the knob lets us use our historically functional
behavior while offering a convenient way to switch on a stock kernel.
The only valid values for hw.efifb.cache_attr at this time are "uc" and
"wc".
