When we're done checking all the records/keys in a btree block, compute
the low and high key of the block and compare them to the associated key
in the parent btree block.

Add to the btree scrubber the ability to check that the keys and
records are in the right order and actually call out to our record
iterator to do actual checking of the records.

Create a function that can check the shape of a btree -- each block
passes basic inspection and all the pointers look ok. In the next patch
we'll add the ability to check the actual keys and records stored within
the btree. Add some helper functions so that we report detailed scrub
errors in a uniform manner in dmesg. These are helper functions for
subsequent patches.
