x86: Harmonize GENERIC and MINIMAL
* Reorder MINIMAL so everything is in the same order as in GENERIC.
* Wherever comments diverged, except for the explanatory comment at
the top, copy the GENERIC version to MINIMAL.
* Add KDTRACE_FRAME to i386 GENERIC; it was already in MINIMAL, and
adding it to GENERIC seemed like the more correct move.
With these changes, MINIMAL is a strict subset of GENERIC, apart from
the identifier and the explanatory comment at the top.

pfsync: remove invalid panic
When we undefer a packet (when the peer acks the state) it's possible
that we don't find a corresponding pfsync_deferral. We panic here, but
that's actually something that can happen in normal operation:
- if we have too many deferred packets already (in pfsync_defer())
- if the deferral timed out (in pfsync_defer_tmo())
Remove this panic and document the scenarios where it might occur.

nfscl: Add support for flexible file layout striping
Commit 72e57bc26417 added support for striping to the pNFS
server configuration. This patch adds support for striping
to the NFS client.
For striped flexible file layouts, an extra structure
must be malloc()d for each stripe, since the number
of stripe servers can vary from one mirror to another.
This new structure is called nfsffs and a single one
of these structures is in the nfsffm structure so that
the non-striped layouts can avoid the additional malloc()'s.
This patch only affects NFSv4.1/4.2 mounts that use the
"pnfs" mount option against servers that support the
flexible file layout.
loader.efi: Fix a comment

ipfw/nat64: Fix type confusion panic when using wrong NAT64 instance type
Add etlv type validation to ipfw_nat64clat() and ipfw_nat64stl() to
verify that the retrieved instance is actually a nat64clat instance
before use.
All NAT64 instance types share the same srvstate[] array but have
different struct layouts.
Without type validation, using the wrong instance type with
a handler causes type confusion and kernel panic.

acpi: Sleep/wake event handlers: Expose first argument's true type
This is for clarification and to slightly simplify code.
At present, the EVENTHANDLER(9) subsystem does not check that the first
argument to the event handler, registered via EVENTHANDLER_REGISTER(),
is of the right type with respect to the type declaration passed to
EVENTHANDLER_DECLARE(), so in that infrastructure no additional safety
is gained by this change.

kern: add a security knob to disable unprivileged access to kenv
We sometimes store sensitive things in the kenv that get zapped, but we
really shouldn't rely on that zapping to actually happen. Most
unprivileged processes don't really need to read from the kernel
environment in the first place, so add a knob that allows it to be
disabled.
Note that we consider jailed root to be unprivileged from this
perspective; they have their own meta/env concepts and we should
encourage users to take advantage of those for passing information to
jails.
