Hi everyone,

This is part 2 of online repair.  This river combines the directory
parent pointer work that I took over from Allison after she departed
with a bunch of new online repair functionality that enables rebuilding
of directory trees and correction of problems with the tree structure.

As a consequence, this river needs closer review than the previous
river.  I've changed the ondisk format of the parent pointers to make it
easier to correct the directory structure, but that required some
alterations to the attr log intent items to support looking up xattrs by
name and value.

AFAICT this part is stable enough for review-- I've been running a few
testvm host systems with parent pointers enabled for about 6 months, and
haven't noticed any problems.  With this part added, there's a dramatic
drop in the number of uncorrectable directory fields reported by the
fuzz test suite.
