percentage of verified groups, interpolating based on snapshot count
within the group. in most cases, this will also be closer to 'real'
progress since added snapshots (those which will be verified) in active
backup groups will be roughly evenly distributed, while number of total
snapshots per group will be heavily skewed towards those groups which
have existed the longest, even though most of those old snapshots will
only be re-verified very infrequently.

BackupInfo::list_backup_groups is identical code-wise, and makes more
sense as entry point for listing groups.

WalkDir does not follow symlinks by default anyway, and this behaviour
is not documented anywhere. e.g., if a sysadmin mounts 'extra storage'
for some backup group or type (not knowing that only metadata is stored
in those directories), GC will ignore all the indices contained within
and happily garbage collect their chunks..

for safety reason, GC finds and marks all index files below the
datastore base path. as a result of regular operations, only index files
within the expected scheme of <TYPE>/<ID>/<TIMESTAMP> should exist.
add a small check + warning if the index list contains index files out
side of this expected scheme, so that an admin with shell access can
investigate.

this is stricter than the check that happened on manifest load, as it
also fails if the manifest is signed but we don't have a key available.
add some additional output at the start of a backup to indicate whether
a previous manifest is available to base the backup on.

Simplify the phase 2 code by treating .bad files just like regular
chunks, with the exception of stat logging.
To facilitate, we need to touch .bad files in phase 1. We only do this
under the condition that 1) the original chunk is missing (as before),
and 2) the original chunk is still referenced somewhere (since the code
lives in the error handler for a failed chunk touch, it only gets called
for chunks we expect to be there, i.e. ones that are referenced).
Untouched they will then be cleaned up after 24 hours (or after the last
longer-running task finishes).
Reason 2) is also a fix for .bad files not being cleaned up at all if
the original is no longer referenced anywhere (e.g. a user deleting all
snapshots after seeing some corrupt chunks appear).
cond_touch_path is introduced to touch arbitrary paths in the chunk
store with the same logic as touching chunks.
