cmd/syncthing: Add decrypt subcommand (#7332)
This adds the `syncthing decrypt` subcommand that is used to
(offline-)decrypt or just verify the contents of an encrypted folder.

lib/model: Correctly verify short read blocks (fixes #7333) (#7334)
An untrusted device will receive padded info for small blocks, and hence
sometimes request a larger block than actually exists on disk.
Previously we let this pass because we didn't have a hash to compare to
in that case and we ignored the EOF error based on that.

Now the untrusted device does pass an encrypted hash that we decrypt and
verify. This means we can't check for len(hash)==0 any more, but on the
other hand we do have a valid hash we can apply to the data we actually
read. If it matches then we don't need to worry about the read
supposedly being a bit short.

lib/model: Forget pending folders no longer announced in ClusterConfig (fixes #5187) (#7205)
* lib/db: Add ExpirePendingFolders().

Use-case is to drop any no-longer-pending folders for a specific
device when parsing its ClusterConfig message where previously offered
folders are not mentioned any more.

The timestamp in ObservedFolder is stored with only second precision,
so round to seconds here as well.  This allows calling the function
within the same second of adding or updating entries.

* lib/model: Weed out pending folders when receiving ClusterConfig.

Filter the entries by timestamp, which must be newer than or equal to
the reception time of the ClusterConfig.  For just mentioned ones,
this assumption will hold as AddOrUpdatePendingFolder() updates the
timestamp.

* lib/model, gui: Notify when one or more pending folders expired.

Introduce new event type FolderOfferCancelled and use it to trigger a
complete refreshCluster() cycle.  Listing individual entries would be
much more code and probably just as much work to answer the API
request.

* lib/model: Add comment and rename ExpirePendingFolders().

* lib/events: Rename FolderOfferCancelled to ClusterPendingChanged.

* lib/model: Reuse ClusterPendingChanged event for cleanPending()

Changing the config does not necessarily mean that the
/resut/cluster/pending endpoints need to be refreshed, but only if
something was actually removed.  Detect this and indicate it through
the ClusterPendingChanged event, which is already hooked up to requery
respective endpoints within the GUI.

No more need for a separate refreshCluster() in reaction to
ConfigSaved event or calling refreshConfig().

* lib/model: Gofmt.

* lib/db: Warn instead of info log for failed removal.

* gui: Fix pending notifications not loading on GUI start.

* lib/db: Use short device ID in log message.

* lib/db: Return list of expired folder IDs after deleting them.

* lib/model: Refactor Pending...Changed events.

* lib/model: Adjust format of removed pending folders enumeration.

Use an array of objects with device / folder ID properties, matching
the other places where it's used.

* lib/db: Drop invalid entries in RemovePendingFoldersBeforeTime().

* lib/model: Gofmt.

My local gofmt did not complain here, strangely...

* gui: Handle PendingDevicesChanged event.

Even though it currently only holds one device at a time, wrap the
contents in an array under the "added" property name.

* lib/model: Fix null values in PendingFoldersChanged removed member.

* gui: Handle PendingFoldersChanged event.

* lib/model: Simplify construction of expiredPendingList.

* lib/model: Reduce code duplication in cleanPending().

Use goto and a label for the common parts of calling the DB removal
function and building the event data part.

* lib/events, gui: Mark ...Rejected events deprecated.

Extend comments explaining the conditions when the replacement event
types are emitted.

* lib/model: Wrap removed devices in array of objects as well.

* lib/db: Use iter.Value() instead of needless db.Get(iter.Key())

* lib/db: Add comment explaining RemovePendingFoldersBeforeTime().

* lib/model: Rename fields folderID and deviceID in event data.

* lib/db: Only list actually expired IDs as removed.

Skip entries where Delete() failed as well as invalid entries that got
removed automatically.

* lib/model: Gofmt

lib/api, lib/model: Avoid contention on filesystem for DB status call (ref #7270) (#7271)
This splits the ignore getting to two methods, one that loads from disk
(the old one) and one that just returns whatever is already loaded (the
new one). The folder summary service which is just interested in stats
now uses the latter method. This means that it, and API calls that call
it, does not get blocked by folder I/O.

lib/config, lib/connections: Add optional connection limits (fixes #7176) (#7223)
This adds two new configuration options:

    // The number of connections at which we stop trying to connect to more
    // devices, zero meaning no limit. Does not affect incoming connections.
    ConnectionLimitEnough int

    // The maximum number of connections which we will allow in total, zero
    // meaning no limit. Affects incoming connections and prevents
    // attempting outgoing connections.
    ConnectionLimitMax int

These can be used to limit the number of concurrent connections in
various ways.

lib/connections, lib/model: Track last connection duration (ref #7223) (#7242)
This adds a statistic to track the last connection duration per device.
It isn't used for much in this PR, but it's available for #7223 to use
in deciding how to order device connection attempts (deprioritizing
devices that just dropped our connection the last time).

lib/fs: Fix TestChmodDir depending on umask (fixes #6551) (#7241)
The test would fail if the umask on UNIX is greater than 0022, because
the OS transparently subtracts it from the mode passed to Mkdir(), as
the Go documentation confirms.

Our goal here is not to test os.Mkdir(), so just make sure the desired
mode is actually set by forcing it afterwards.

lib/connections: Refactor connection loop (#7177)
This breaks out some methods from the connection loop to make it simpler
to manage and understand.

Some slight simplifications to remove the `seen` variable (we can filter
`nextDial` based on times are in the future or not, so we don't need to
track `seen`) and adding a minimum loop interval (5s) in case some
dialer goes haywire and requests a 0s redial interval or such.

Otherwise no significant behavioral changes.
