lib/ur: Plug file descriptor leak in Linux memorySize (#7266)

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.

-### DO NOT REPORT SECURITY ISSUES IN THIS ISSUE TRACKER
-
-Instead, contact security@syncthing.net directly - see
-https://syncthing.net/security.html for more information.
-
-### DO NOT POST SUPPORT REQUESTS OR GENERAL QUESTIONS IN THIS ISSUE TRACKER
-
-Please use the forum at https://forum.syncthing.net/ where a large number of
-helpful people hang out. This issue tracker is for reporting bugs or feature
-requests directly to the developers. Worst case you might get a short
-"that's a bug, please report it on GitHub" response on the forum, in which
-case we thank you for your patience and following our advice. :)
-
-### Please use the correct issue tracker
-
-If your problem relates to a Syncthing wrapper or [sub-project](https://github.com/syncthing) such as [Syncthing for Android](https://github.com/syncthing/syncthing-android/issues), [SyncTrayzor](https://github.com/canton7/synctrayzor) or the [documentation](https://github.com/syncthing/docs/issues), please use their respective issue trackers.
-
-### Does your log mention database corruption?
-
-If your Syncthing log reports panics because of database corruption it is most likely a fault with your system's storage or memory. Affected log entries will contain lines starting with `panic: leveldb`. You will need to delete the index database to clear this, by running `syncthing -reset-database`.
-
-### Please do post actual bug reports and feature requests.
-
-If your issue is a bug report, replace this boilerplate with a description
-of the problem, being sure to include at least:
-
- - what happened,
- - what you expected to happen instead, and
- - any steps to reproduce the problem.
-
-Also fill out the version information below and add log output or
-screenshots as appropriate.
-
-If your issue is a feature request, simply replace this template text in
-its entirety.
-
-### Version Information
-
-Syncthing Version: v0.x.y
-OS Version: Windows 7 / Ubuntu 14.04 / ...
-Browser Version: (if applicable, for GUI issues)
