v4:
- pass around fsinfo instead of separate array and length args
v3:
- use sort() from lib/sort.c to sort the list
v2:
- rework Tigran's patch to preserve existing selection behaviour
- simplify layout driver selection by sorting the list
This is v4 of the patchset. The main change is the change to pass
around the fsinfo instead of separate array pointer and length args.
Only lightly tested by mounting a server that sends both flexfiles and
block layouts. The client successfully selected the block layout in most
cases, but if I blacklist blocklayoutdriver then it selects flexfiles
instead.

pnfs: track multiple layout types in fsinfo structure
pnfs: add a new mechanism to select a layout driver according to an
ordered list
