Update the driver to use iflib in order to bring performance,
maintainability, and (hopefully) stability benefits to the driver.
The driver currently isn't completely ported; features that are missing:
- VF driver (ixlv)
- SR-IOV host support
- RDMA support
The plan is to have these re-added to the driver before the next FreeBSD release.

In some cases, the required information is not available and the
UDP provider reported an empty string in this case and the IP
and TCP provider reported a NULL pointer.
This patch changes the value provided in this case to the string
"<unknown>". This make the behaviour consistent and in-line with
the behaviour of Solaris.

Reduce by 1 the number of crazy libraries we need in stand by moving
geli into libsa (where architecturally it belonged all along). This
just moves things around without any code changes.
To conform to RFC 5426, this function is intended to truncate messages
if they exceed the message size limits. Unfortunately, the amount of
space was computed the wrong way around, causing messages to be
truncated entirely.

The usermgmt API was stomping on a global ($user_gid to be specific)
so things would appear to work fine until you tried to make a second
pass into the API with the now-tainted variable contents.
Fixed by localizing menu-specific contents as to not leak outside API.

- In iflib_msix_init(), VMMs with broken MSI-X activation are trying
to be worked around by manually enabling PCIM_MSIXCTRL_MSIX_ENABLE
before calling pci_alloc_msix(9). Apart from constituting a layering
violation, this has the problem of leaving PCIM_MSIXCTRL_MSIX_ENABLE
enabled when falling back to MSI or INTx when e. g. MSI-X is black-
listed and initially also when disabled via hw.pci.enable_msix. The
later in turn was incorrectly worked around in r325166.
Since r310806, pci(4) itself has code to deal with broken MSI-X
handling of VMMs, so all of these workarounds in iflib(9) can go,
fixing non-working interrupts when falling back to MSI/INTx. In
any case, possibly further adjustments to broken MSI-X activation
of VMMs like enabling r310806 by default in VM environments need to
be placed into pci(4), not iflib(9). [1]
- Also remove the pci_enable_busmaster(9) call from iflib_msix_init(),
which is already more properly invoked from iflib_device_attach().
- When falling back to MSI/INTx, release the MSI-X BAR resource again.
- When falling back to INTx, ensure scctx->isc_vectors is set to 1 and
not to something higher from a device with more than one MSI message
supported.
- Make the nearby ring_state(s) stuff (static) const.

Casting from rman_res_t to a pointer results in "cast to pointer from
integer of different size" warnings with base gcc on i386, so use an
intermediate cast to uintptr_t to suppress it. In this case, the I/O
port range is effectively limited to the range of 0..65535.

Add a few intermediate casts to intptr_t to suppress "cast to pointer
from integer of different size" warnings from gcc. In this case, the
'arg2' part of SYSCTL_HANDLER_ARGS is used to pass in a pointer, via an
intermediate intmax_t, so no information is lost.

The Flexible File layout LayoutReturn operation has argument fields where
an I/O error encountered when attempting I/O on a DS can be reported back
to the MDS.
This patch adds code to the client to do this for the Flexible File layout
mirrored case.
This patch should only affect mounts using the "pnfs" option against servers
that support the Flexible File layout.

When running mckey, errors may happen in the init/connect stage.
When leaving multicast groups, we override this value.
Fix that by saving the return value from rdma_leave_multicast to different
parameter, and only in case of failure in rdma_leave_multicast override it.
