... and remove 8/10 implementations, which were no-ops. This saves code

lib/nat: Fix race condition in Mapping (#8042)
The locking protocol in nat.Mapping was racy:

* Mapping.addressMap RLock'd, but then returned a map shared between
  caller and Mapping, so the lock didn't do anything.

* Operations inside Service.{verifyExistingMappings,acquireNewMappings}
  would lock the map for every update, but that means callers to
  Mapping.ExternalAddresses can be looping over the map while the
  Service methods are concurrently modifying it. When the Go runtime
  detects that happening, it panics.

* Mapping.expires was read and updated without locking.

The Service methods now lock the map once and release the lock only when
done.

Also, subscribers no longer get the added and removed addresses, because
none of them were using the information. This was changed for a previous
attempt to retain the fine-grained locking and not reverted because it
simplifies the code.

lib/syncthing: Clean up / refactor LoadOrGenerateCertificate() utility function. (#8025)
LoadOrGenerateCertificate() takes two file path arguments, but then
uses the locations package to determine the actual path.  Fix that
with a minimally invasive change, by using the arguments instead.
Factor out GenerateCertificate().

The only caller of this function is cmd/syncthing, which passes the
same values, so this is technically a no-op.

* lib/tlsutil: Make storing generated certificate optional.  Avoid
  temporary cert and key files in tests, keep cert in memory.

lib/connections: Fix and optimize registry (#7996)
Registry.Get used a full sort to get the minimum of a list, and the sort
was broken because util.AddressUnspecifiedLess assumed it could find out
whether an address is IPv4 or IPv6 from its Network method. However,
net.(TCP|UDP)Addr.Network always returns "tcp"/"udp".

all: Truncate some timestamps (fixes #7457) (#7459)
This truncates times meant for API consumption to second precision,
where fractions won't typically matter or add any value. Exception to
this is timestamps on logs and events, and of course I'm not touching
things like file metadata.

I'm not 100% certain this is an exhaustive change, but it's the things I
found by grepping and following the breadcrumbs from lib/api...

I also considered general-but-ugly solutions, like having the API
serializer itself do reflection magic or even regexps on returned
objects, but decided against it because aurgh...

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/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.

lib/connections: Handle QUIC not being available (#7186)
This does two things:

- Exclude QUIC from go1.16 builds, automatically, for now, since it
  doesn't work and just panics.

- Provide some fake listeners and dialers when QUIC is disabled.

These fake listeners and dialers indicate that they are disabled and
unsupported, which silences "Dialing $address: unknown address scheme:
quic" type of stuff which is not super helpful to the user.
