v1.13.0

This release adds configuration options for min/max connections (see
https://docs.syncthing.net/advanced/option-connection-limits.html) and
moves the storage of pending devices/folders from the config to the
database (see
https://docs.syncthing.net/dev/rest.html#cluster-endpoints,
https://docs.syncthing.net/events/pendingdeviceschanged.html, and
https://docs.syncthing.net/events/pendingfolderschanged.html).

Bugfixes:

- #7005: panic: nil pointer dereference because (*db.Lowlevel)getMetaAndCheck() returns nil
- #7076: File not detected due to watching reporting events on old, deleted path
- #7165: Connections aren't actually closed when closing a protocol connection
- #7184: Spurious unexpected directory in untrusted folder
- #7197: In Recent Changes, the Device column is empty
- #7231: panic: deadlock detected at fmut

Enhancements:

- #7176: Active connections min/max setting
- #7178: Pending devices and folders should live in the database instead of configuration

Other issues:

- #6551: Test failure because of umask
