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.

A lot of ipath layer code was only called in one place. Now that the
ipath_core and ib_ipath drivers are merged, it's more sensible to simply
inline the simple stuff that the layer code was doing.

There is little point in keeping the two drivers separate, so we are
merging them.

We can't tell for sure if any packets are in the infinipath receive buffer
when we shut down a chip port. Normally this is taken care of by orderly
shutdown, but when processes are terminated, or sending process has a bug, we
can continue to receive packets. So rather than writing zero to the address
registers for the closing port, we point it at a dummy memory.

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.

This patch fixes some problems uncovered during IB compliance testing to
return the right values for error counters returned by the Performance Get

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).

There is no longer a /dev/ipath_diag file; instead, there's
/dev/ipath_diag0, 1, etc.
It's still not possible to have diags run on more than one unit at a time,
but that's easy to fix at some point.

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.
