Note that for now we do not create a separate library for libdivsufsort
because it's not used anywhere else.

This was a regression from r300349.
Setting MK_CROSS_COMPILER=no forces the compiler bootstraping *and* the
binutils/elftoolchain bootstrapping to be disabled in share/mk/src.opts.mk.
The only intent with using an external compiler is to disable bootstrapping of
the compiler. The binutils/elftoolchain bootstrapping must still occur unless
XAS is set. This did not affect WITH_SYSTEM_COMPILER.
Now that setting an external compiler sets both MK_CLANG_BOOTSTRAP and
MK_GCC_BOOTSTRAP to no, and MK_CROSS_COMPILER does the same via
share/mk/src/opts.mk, remove redundant logic that checks for
MK_CROSS_COMPILER. It will not always be true now that MK_CROSS_COMPILER==no
when an external compiler is used and --sysroot/-target is needed.

1. Always calculate what the expected values are.
2. Add 'make test-system-compiler' to show all of the computed values
vs the wanted values.
3. Extend the .info line to buildkernel/kernel-toolchain/toolchain/_cross-tools.
4. Consolidate all of the logic to one condition.

Calling it earlier increases the window when MSIX info may change.
This change does not solve the problem completely, but seems logical.
Complete solution should probably include link reset in case of MSIX
remap to trigger new negotiation, but we have no way to get notified
about that now.
Split implementation of nvram2env to generic (MI) & MIPS-based code:
- removed includes like "*siba*", because they are unused
- added nvram2env_mips.c file with MIPS-specific code, code moved from nvram2env.c
- added header file to shared defines/structures/function prototypes between MI and MIPS code
Also this fix allows to implement own nvram2env drivers.

vesa_init_done isn't a reliable guard for the mutex init. If
vesa_configure() doesn't find valid VESA info it will not set
vesa_init_done, but the lock will remain initialized. Revert r303076
and use MTX_SYSINIT to deterministically init the lock.

Chelsio NICs are a bit unique compared to some other NICs in that they
expose different functionality on different physical functions. In
particular, PF4 is used to manage the NIC interfaces ('t4nex' and 't5nex').
However, PF4 is not able to create VF devices. Instead, VFs are only
supported by physical functions 0 through 3. This commit adds 't4iov'
and 't5iov' drivers that attach to PF0-3.
One extra wrinkle is that the iov devices cannot enable SR-IOV until the
firwmare has been initialized by the main PF4 driver. To handle this
case, a new t4_if kobj interface has been added to permit cross-calls
between the PF drivers. The PF4 driver notifies sibling drivers when it
is fully attached. It also requests sibling drivers to detach before it
detaches. Sibling drivers query the PF4 driver during their attach
routine to see if it is attached. If not, the sibling drivers defer
their attach actions until the PF4 driver informs them it is attached.
VF devices are associated with a single port on the NIC. VF devices
created from PF0 are associated with the first port on the NIC, VFs
from PF1 are associated with the second port, etc. VF devices can
only be created from a PF device that has an associated port. Thus,
on a 2-port card, VFs are only supported on PF0 and PF1.

If a driver sends an malformed or disallowed work request, the firmware
responds with a work request error. Previously the driver treated this is
as an unexpected message and panicked. Now it decodes the error message
to aid in debugging.
