Fix a potential deadlock in handling the DERPmap.

Send & receive Taildrop files. To receive, create a shared folder named "Taildrop" and in Permissions, give the System user tailscale read/write access, then restart Tailscale.
This was developed for 1.20 but also backported to 1.18.2.

Bugfixes

• make exit node selection take effect (almost) immediately
• permit protocols other than TCP+UDP if ACL allows
• fix receiving taildrop files

General improvements

• Resolve connectivity issue where a DISCO key was assumed to map to one node when in reality it could be any of several nodes.

Platform specific

Synology

• don't try to delete legacy netfilter rules, they don't exist on Synology
• only use AmbientCaps on DSM7+
