Update to what the previous code seemed to be doing via the correct
interfaces. Further issues exist in xge_ioctl_registers(), but this is
debugging code in a driver that has few users and they don't appear to
be crashes or leaks.

No functional change in practice. If the sbni driver supported
64-bit big-endian system, this would be an ABI changes, but it is
i386-only. The old version leaked a word of stack on 64-bit systems.
This eliminates the only assignment to ifr_data.

Requests to modify the state of TLS connections need to be sent on the
same queue as TLS record transmit requests to ensure ordering.
However, in order to use the offload transmit queue in t4_set_tcb_field(),
the function needs to be updated to do proper flow control / credit
management when queueing a request to an offload queue. This required
passing a pointer to the toepcb itself to this function, so while here
remove the 'tid' and 'iqid' parameters and obtain those values from the
toepcb in t4_set_tcb_field() itself.

It is random collection of fixes for issues not yet corrected,
reported at https://tsyrklevi.ch/clang_analyzer/freebsd_013017/. Many
issues from that list were already corrected. Most of them are for
compat32, old compat32 or affect both primary host ABI and compat32.
The freebsd32_kldstat(), for instance, was already fixed by using
malloc(M_ZERO). Patch includes correction to report the supplied

xforms that support processing of multiple blocks at a time (to support more
efficient modes, for example) can define the encrypt_ and decrypt_multi
interfaces. If these interfaces are not present, the generic cryptosoft
code falls back on the block-at-a-time encrypt/decrypt interfaces.
Stream ciphers may support arbitrarily sized inputs (equivalent to an input
block size of 1 byte) but may be more efficient if a larger block is passed.

According to 802.1Q-2014, VLAN tagged packets with VLAN id 0 should be
considered as untagged, and only PCP and DEI values from the VLAN tag
are meaningful. See for instance
https://www.cisco.com/c/en/us/td/docs/switches/connectedgrid/cg-switch-sw-master/software/configuration/guide/vlan0/b_vlan_0.html.
Make it possible to specify PCP value for outgoing packets on an
ethernet interface. When PCP is supplied, the tag is appended, VLAN
id set to 0, and PCP is filled by the supplied value. The code to do
VLAN tag encapsulation is refactored from the if_vlan.c and moved into
if_ethersubr.c.
Drivers might have issues with filtering VID 0 packets on
receive. This bug should be fixed for each driver.

If the operation is not an update, if neither r/w nor r/o mode is
explicitly requested, if the error code hints at the possibility of the
media being read-only, and if the fallback is allowed, then we can try
to automatically downgrade to the readonly mode.
This is especially useful for auto-mounting of removable media that
sometimes can happen to be write-protected.
The fallback to r/o is not enabled by default. It can be requested on a
per-mount basis with a new mount option, 'autoro'. Or it can be
globally allowed by setting vfs.default_autoro.

No functional change for Skipjack, AES-ICM, Blowfish, CAST-128, Camellia,
DES3, Rijndael128, DES. All of these have identical IV and blocksizes
declared in the associated enc_xform.
Functional changes for:
* AES-GCM: block len of 1, IV len of 12
* AES-XTS: block len of 16, IV len of 8
* NULL: block len of 4, IV len of 0
For these, it seems like the IV specified in the enc_xform is correct (and
the blocksize used before was wrong).
Additionally, the not-yet-OCFed cipher Chacha20 has a logical block length
of 1 byte, and a 16 byte IV + nonce.
Rationalize references to IV lengths to refer to the declared ivsize, rather
than declared blocksize.

To fix the GCC build, remove multiple redundant declarations of
vmci_send_datagram() (the copy in vmci.h as well as the extern definition in
vmci_queue_pair.c were wholly redundant).
Also to fix the GCC build, include a non-empty format string in the vmci(4)
definition of ASSERT(). It seems harmless either way, but adding the
stringified invariant is easier than masking the warning.
The other vmci_kernel_defs.h changes are cosmetic and simply match macros to
existing definitions.

It was previously only printed, but we do actually want to raise it as a
full blown error so that things don't look OK when they've actually gone
wrong.
The second parameter to error, level, is set to 2 here so that the error
message reflects the position of the try_include caller, rather than the
try_include itself. Example:
LUA ERROR: /boot/lua/loader.lua:46: /boot/lua/local.lua:1: attempt to call a
nil value (global 'cxcint').
This provides a way to optionally include a module without having to wrap it
in filesystem checks. try_include is a little more robust, using the lua
search path instead of forcing us to explicitly consider all of the places
we could want to include a module. Errors are still generally raised from
trying to load the module, but ENOENT will not get raised unless we're doing
a verbose load.
This will also be used to split out logo/brand graphics into their own files
so that we can safely scale up the number of graphics included without
worrying about the extra memory consumption- opting to lazily load graphics
instead.
