Update the Linux compatibility layer:
- Add more functions.
- Add some missing includes which are needed when the header files
are not included in a particular order.
- The kasprintf() function cannot be inlined due to using a variable
number of arguments. Move it to a C-file.
- Fix problems about 32-bit ticks wraparound and unsigned long
conversion. Jiffies or ticks in FreeBSD have integer type and are
not long.
- Add missing "order_base_2()" macro.
- Fix BUILD_BUG_ON() macro.
- Declare a missing symbol which is needed when compiling without -O2
- Clean up header file inclusions in the linux/completion.h, linux/in.h
and linux/fs.h header files.

MFC r276749:
Fixes and updates for the Linux compatibility layer:
- Remove unsupported "bus" field from "struct pci_dev".
- Fix logic inside "pci_enable_msix()" when the number of allocated
interrupts are less than the number of available interrupts.
- Update header files included from "list.h".
- Ensure that "idr_destroy()" removes all entries before destroying
the IDR root node(s).
- Set the "device->release" function so that we don't leak memory at
device destruction.
- Use FreeBSD's "log()" function for certain debug printouts.
- Put parenthesis around arguments inside the min, max, min_t and max_t macros.
- Make sure we don't leak file descriptors by dropping the extra file
reference counts done by the FreeBSD kernel when calling falloc()
and fget_unlocked().

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.
