Update OFED to Linux 3.7 and update Mellanox drivers.

Update the OFED Infiniband core to the version supplied in Linux
version 3.7.

The update to OFED is nearly all additional defines and functions
with the exception of the addition of additional parameters to
ib_register_device() and the reg_user_mr callback.

In addition the ibcore (Infiniband core) and ipoib (IP over Infiniband)
have both been made into completely loadable modules to facilitate
testing of the OFED stack in FreeBSD.

Finally the Mellanox Infiniband drivers are now updated to the
latest version shipping with Linux 3.7.

Redo r242842, now actually fixing the warnings, as follows:
- In sys/ofed/drivers/infiniband/core/cma.c, an enum struct member is
interpreted as an int, so cast it to an int.
- In sys/ofed/drivers/infiniband/core/ud_header.c, initialize the
packet_length variable in ib_ud_header_init(), to prevent undefined
behaviour.
- In sys/ofed/drivers/infiniband/ulp/sdp/sdp_rx.c, call rdma_notify()
with the correct enum type and value.
- In sys/ofed/include/linux/pci.h, change the PCI_DEVICE and PCI_VDEVICE
macros to use C99 struct initializers, so additional members can be
overridden.

Align the PCI Express #defines with the style used for the PCI-X
#defines. This also has the advantage that it makes the names more
compact, iand also allows us to correct the non-uniform naming of
the PCIM_LINK_* defines, making them all consistent amongst themselves.

This is a mostly mechanical rename:
s/PCIR_EXPRESS_/PCIER_/g
s/PCIM_EXP_/PCIEM_/g
s/PCIM_LINK_/PCIEM_LINK_/g

When this is MFC'd, #defines will be added for the old names to assist
out-of-tree drivers.

Do a sweep of the tree replacing calls to pci_find_extcap() with calls to
pci_find_cap() instead.

- Merge in OFED 1.5.3 from projects/ofed/head
