Subject: reduce some recovery logging

Make minzip log only a count of files when extracting, not individual
filenames.  Make patching only chatter about free space if there's not
enough and compact the other messages.

Only the last 8k of the recovery log gets uploaded; this makes it more
likely that we will get all of it.
