lib/protocol: Refactor interface (#9375)
This is a refactor of the protocol/model interface to take the actual
message as the parameter, instead of the broken-out fields:

```diff
type Model interface {
        // An index was received from the peer device
-       Index(conn Connection, folder string, files []FileInfo) error
+       Index(conn Connection, idx *Index) error
        // An index update was received from the peer device
-       IndexUpdate(conn Connection, folder string, files []FileInfo) error
+       IndexUpdate(conn Connection, idxUp *IndexUpdate) error
        // A request was made by the peer device
-       Request(conn Connection, folder, name string, blockNo, size int32, offset int64, hash []byte, weakHash uint32, fromTemporary bool) (RequestResponse, error)
+       Request(conn Connection, req *Request) (RequestResponse, error)
        // A cluster configuration message was received
-       ClusterConfig(conn Connection, config ClusterConfig) error
+       ClusterConfig(conn Connection, config *ClusterConfig) error
        // The peer device closed the connection or an error occurred
        Closed(conn Connection, err error)
        // The peer device sent progress updates for the files it is currently downloading
-       DownloadProgress(conn Connection, folder string, updates []FileDownloadProgressUpdate) error
+       DownloadProgress(conn Connection, p *DownloadProgress) error
 }
```

(and changing the `ClusterConfig` to `*ClusterConfig` for symmetry;
we'll be forced to use all pointers everywhere at some point anyway...)

The reason for this is that I have another thing cooking which is a
small troubleshooting change to check index consistency during transfer.
This required adding a field or two to the index/indexupdate messages,
and plumbing the extra parameters in umpteen changes is almost as big a
diff as this is. I figured let's do it once and avoid having to do that
in the future again...

The rest of the diff falls out of the change above, much of it being in
test code where we run these methods manually...

all: Support multiple device connections (fixes #141) (#8918)
This adds the ability to have multiple concurrent connections to a single device. This is primarily useful when the network has multiple physical links for aggregated bandwidth. A single connection will never see a higher rate than a single link can give, but multiple connections are load-balanced over multiple links.

It is also incidentally useful for older multi-core CPUs, where bandwidth could be limited by the TLS performance of a single CPU core -- using multiple connections achieves concurrency in the required crypto calculations...

lib/protocol: Handle encrypted requests without encrypted hash (fixes #8277) (#8827)
The layout of the request differs based on whether it comes from an
untrusted device or a trusted device with encrypted enabled. Handle
both.

Closes #8819.

lib/protocol: Cache expensive key operations (fixes #8599) (#8820)
This adds a cache to the expensive key generation operations. It's fixes
size LRU/MRU stuff to keep memory usage bounded under absurd conditions.

Also closes #8600.
