hal_ks_index_fsck() and a pile of debugging code.
The debugging code was for tracking down what turned out to be a race
condition in the Alpha's flash driver code (see sw/stm32); much of
this was temporary, and will be removed in a (near) future commit, but
some of the techniques were useful and belong in the repository in
case we need to pull them back for something similar in the future.
hal_ks_index_fsck() attempts to diagnose all the things I found wrong
in the ks_flash index after one long series of errors. As presently
written, it doesn't attempt to fix anything, just diagnose errors: the
intent is that we can call this, before and after every modification
if necessary, to poinpoint exactly which calls introduce errors. Once
things stablize a bit, we may want to crank down the number of calls
to this (it's a bit expensive, since it checks the entire index), and
perhaps add the ability to clean up whatever errors it might find; the
latter might be a good candidate for a CLI command.
