c01742855a KeyConfig: bail on wrong fingerprint
instead of just logging the error. this should never happen in practice
unless someone is messing with the keyfile, in which case, it's better
to abort.

update tests accordingly (wrong fingerprint should fail, no fingerprint
should get the expected one).

179145dc24 backup/datastore: move manifest locking to /run
this fixes the issue that on some filesystems, you cannot recursively
remove a directory when you hold a lock on a file inside (e.g. nfs/cifs)

it is not really backwards compatible (so during an upgrade, there
could be two daemons have the lock), but since the locking was
broken before (see previous patch) it should not really matter
(also it seems very unlikely that someone will trigger this)

7e25b9aaaa verify: use same progress as pull
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.

844660036b gc: don't limit index listing to same filesystem
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..

datastore base path. as a result of regular operations, only index files

fd19256470 gc: treat .bad files like regular chunks
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.

5499bd3dee fix #2998: encode mtime as i64 instead of u64
saves files mtime as i64 instead of u64 which enables backup of
files with negative mtime

the catalog_decode_i64 is compatible to encoded u64 values (if < 2^63)
but not reverse, so all "old" catalogs can be read with the new
decoder, but catalogs that contain negative mtimes will decode wrongly
on older clients

also remove the arbitrary maximum value of 2^63 - 1 for
encode_u64 (we just use up to 10 bytes now) and correctly
decode them and update the comments accordingly

adds also test for i64 encode/decode and for compatibility between
u64 encode and i64 decode

b4b14dc16e do_verification_job: fix "never-reverify" and refactor/comment
commit a4915dfc2b made a wrong fix, as
it did not observed that the last expressions was done under the
invariant that we had a last verification result, because if none
could be loaded we already returned true (include).

It thus broke the case for "never re-verify", which is important when
using multiple schedules, a more high frequent one for new,
unverified snapshots, and a low frequency to re-verify older snapshots,
e.g., monthly.

Fix this case again, rework the code to avoid this easy to oversee
invariant. Use a nested match to better express the implication of
each setting, and add some comments.
