When we first submitted a userspace subnet management agent, it was
rejected, so we left it out of the final driver submission. This patch
removes a number of vestigial references to it.

Remove ips namespace from infinipath drivers. This renames ips_common.h to
ipath_common.h. Definitions, data structures, etc. that were not used by
kernel modules have moved to user-only headers. All names including ips have
been renamed to ipath. Some names have had an ipath prefix added.

We do a few more explicit checks for specific models, and now also support the
old PathScale serial number style, or new QLogic style.
This is backwards compatible with previous versions of software and hardware.
That is, older software will see a plausible serial number and correct GUID
when used with a new board, while newer software will correctly handle an
older board.

The two arrays only had space for 4 units.
Also changed from ipath_set_sps_lid() to ipath_set_lid(); the sps was
leftover.

Also count the number of interrupts where that works (fastrcvint). On any
interrupt where the port0 head and tail registers are not equal, just call the
ipath_kreceive code without reading the interrupt status, thus saving the
approximately 0.25usec processor stall waiting for the read to return. If any
other interrupt bits are set, or head==tail, take the normal path, but that
has been reordered to handle read ahead of pioavail. Also no longer call
ipath_kreceive() from ipath_qcheck(), because that just seems to make things
worse, and isn't really buying us anything, these days.
Also no longer loop in ipath_kreceive(); better to not hold things off too
long (I saw many cases where we would loop 4-8 times, and handle thousands (up
to 3500) in a single call).

Made in-memory rcvhdrq tail update be in dma_alloc'ed memory, not random user
or special kernel (needed for ppc, also "just the right thing to do").
Some cleanups to make unexpected link transitions less likely to produce
complaints about packet errors, and also to not leave SMA packets stuck and
unable to go out.
A few other random debug and comment cleanups.
Always init rcvhdrq head/tail registers to 0, to avoid race conditions (should
have been that way some time ago).

ipath_common.h and ips_common.h contain definitions shared between
userspace and the kernel.
ipath_kernel.h is the core driver header file.
ipath_debug.h contains mask values used for controlling driver debugging.
ipath_registers.h contains bitmask definitions used in chip registers.
