tweak the ProgressMeter code to always record sizes, even in the stub case
turn out-of-order extraction back on.
- separate extraction into extract/tie methods, with slightly overlapping code
- early exit when we only have tied entries
- mark location as early_exit in that case, since we're gonna close the archive
early
activate "out-of-order" archives based on history
things to watch out for:
- correct handling of multiple files with the same sha
- cwd handling. This is already destated, so we can call set_destdir on
each entry's cwd, instead of relying on @cwd being in the "right" location
as that's no longer the case...
KASSERT() the correct node if a hint is passed to rn_delete().

Fix a panic when trying to remove a route with the magical 0.0.0.0
destination.

looks ok to claudio@
