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.

ee7c28f5e6 backup: reduce calls to time.Now
Archiver.Save queries the current time multiple times. This commit
removes one of these calls as they showed up while profiling a backup of
a nearly unchanged dataset containing 3 million files.

b513597546 internal/restic: Make FileType a uint8 instead of a string
The string form was presumably useful before the introduction of
layouts, but right now it just makes call sequences and garbage
collection more expensive (the latter because every string contains
a pointer to be scanned).

22147e1e02 all: Minor cleanups
if x { return true } return false => return x

	fmt.Sprintf("%v", x) => fmt.Sprint(x) or x.String()

The fmt.Sprintf idiom is still used in the SecretString tests, where it
serves security hardening.

d03460010f internal/restic: Fix ID.UnmarshalJSON, ParseID
ID.UnmarshalJSON accepted non-JSON input with ' as the string delimiter.
Also, the error message for non-hex input was less informative than it
could be and it performed too many checks.

Changed ParseID to keep the error messages consistent.

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.

0e155fd9a6 internal/restic: Fix UID/GID parsing
The helper function uidGidInt used strconv.ParseInt instead of
ParseUint, so it silently ignored some invalid user/group IDs.

Also, improve the error message. "Invalid UID" is more informative than
having "ParseInt" twice (*strconv.NumError displays the function name).

Finally, the user.User struct can be passed by pointer to get reduce
code size.

d4aadfa389 all: Drop ctxhttp
This package is no longer needed, since we can use the stdlib's
http.NewRequestWithContext.

backend/rclone already did, but it needed a different error check due to
a difference between net/http and ctxhttp.

Also, store the http.Client by value in the REST backend (changed to a
pointer when ctxhttp was introduced) and use errors.WithStack instead
of errors.Wrap where the message was no longer accurate. Errors from
http.NewRequestWithContext will start with "net/http" or "net/url", so
they're easy to identify.
