The original qib submission contained a sysfs "stats"
file the reported multiple values with multiple lines.
This set of patches adds a debugfs to replace that
functionality for supportablity reasons.
The first patch adjusts QP reference counting as a prerequisite.
The final patches are all based on the seq_file api to allow
access information from internal qib data structures.
The next patches add:
- IBTA opcode counters
- per receive context countes
- per QP attributes
