05651d6d4f prune: Correctly count used/duplicate blobs for partially compressed repos
Counting the first occurrence of a duplicate blob as used and counting
all other as duplicates, independent of which instance of the blob is
kept, is only accurate if all copies of the blob have the same size. This
is no longer the case for a repository containing both compressed and
uncompressed blobs.

Thus for duplicated blobs first count all instances as duplicates and
then subtract the actually used instance later on.

68c9cb9c6a prune: Shrink keepBlobs set if possible
As long as only a small fraction of the data in a repository is
rewritten, the keepBlobs set will be rather small after cleaning it up.
As golang maps do not shrink their memory usage, just copy the contents
over to a new map. However, only copy the map if the cleanup removed at
least half the entries.

c4fc5c97f9 prune: Use a single CountedBlobSet to track blobs
The set covers necessary, existing and duplicate blobs. This removes the
duplicate sets used to track whether all necessary blobs also exist.
This reduces the memory usage of prune by about 20-30%.

5c7a9a739a backend: Split RetryBackend into own package
The RetryBackend tests depend on the mock backend. When the Backend
interface is eventually split from the restic package, this will lead to
a dependency cycle between backend and backend/mock. Thus split the
RetryBackend into a separate package to avoid this problem.

99547518cd lock: fix flaky TestLockFailedRefresh
The comparison of the current time and the last lock refresh were using
seconds represented as integers. As the test only waits for up to one
second, the associated number truncation can cause the test to take
longer than once second and thus to fail.

Switch to nanoseconds to avoid this problem. This also slightly speeds
up the test.

95a1bb4261 restic: Rework error handling of FindFilteredSnapshots and handle snapshotIDs
FindFilteredSnapshots no longer prints errors during snapshot loading on
stderr, but instead passes the error to the callback to allow the caller
to decide on what to do.

In addition, it moves the logic to handle an explicit snapshot list from
the main package to restic.

07e5c38361 errors: Drop Cause in favor of Go 1.13 error handling
The only use cases in the code were in errors.IsFatal, backend/b2,
which needs a workaround, and backend.ParseLayout. The last of these
requires all backends to implement error unwrapping in IsNotExist.
All backends except gs already did that.

49126796d0 lock: fix timer expiry monitoring during standby
Monotonic timers are paused during standby. Thus these timers won't fire
after waking up. Fall back to periodic polling to detect too large clock
jumps. See https://github.com/golang/go/issues/35012 for a discussion of
go timers during standby.

d92957dd78 lock: Implement strict lock expiry monitoring
Restic continued e.g. a backup task even when it failed to renew the
lock or failed to do so in time. For example if a backup client enters
standby during the backup this can allow other operations like `prune`
to run in the meantime (after calling `unlock`). After leaving standby
the backup client will continue its backup and upload indexes which
refer pack files that were removed in the meantime.

This commit introduces a goroutine explicitly monitoring for locks that
are not refreshed in time. To simplify the implementation there's now a
separate goroutine to refresh the lock and monitor for timeouts for each
lock. The monitoring goroutine would now cause the backup to fail as the
client has lost it's lock in the meantime.

The lock refresh goroutines are bound to the context used to lock the
repository initially. The context returned by `lockRepo` is also
cancelled when any of the goroutines exits. This ensures that the
context is cancelled whenever for any reason the lock is no longer
refreshed.

985722b102 Remove ctx from globalOptions
Previously the global context was either accessed via gopts.ctx,
stored in a local variable and then used within that function or
sometimes both. This makes it very hard to follow which ctx or a wrapped
version of it reaches which method.

Thus just drop the context from the globalOptions struct and pass it
explicitly to every command line handler method.

5b6a77058a Enable sparseness only conditionally
We can either preallocate storage for a file or sparsify it. This
detects a pack file as sparse if it contains an all zero block or
consists of only one block. As the file sparsification is just an
approximation, hide it behind a `--sparse` parameter.

`restic unlock` now only shows `successfully removed locks` if there were locks to be removed.
In addition, it also reports the number of the removed lock files.
