When cap(permanentRelays) >= len(permanentRelays) + len(knownRelays),
append(permanentRelays, knownRelays...)
returns a slice of the array underlying permanentRelays. The subsequent
rand.Shuffle then mixes the permanent and known relays. Sequential
requests may cause strelaypoolsrv to forget its permanent relays. Worse,
concurrent requests may cause shuffling of the same slice on multiple
processors concurrently.

With this change we emulate a case sensitive filesystem on top of
insensitive filesystems. This means we correctly pick up case-only renames
and throw a case conflict error when there would be multiple files differing
only in case.
This safety check has a small performance hit (about 20% more filesystem
operations when scanning for changes). The new advanced folder option
`caseSensitiveFS` can be used to disable the safety checks, retaining the
previous behavior on systems known to be fully case sensitive.

This matches the convention of the stdlib and avoids ambiguity: when
customErr{} and &customErr{} both implement error, client code needs to
check for both.
Memory use should remain the same, since storing a non-pointer type in
an interface value still copies the value to the heap.
This extracts the extra tags from any `[foo]` stuff at the end of the
version and sends them to Sentry for indexing.
If I need to modify that regexp again I'll probably write a from scratch
tokenizer and parser for our version string instead...
Group the global list of files by version, instead of having one flat list for all devices. This removes lots of duplicate protocol.Vectors.

* cmd/stindex: Unify access to key from cached variable.
Avoid calling the Key() method from the iterator each time the value
is needed. Just reuse the cache variable already assigned before the
switch block.
* cmd/stindex: Display the prefix byte value for unknown key types.
Make it easier to diagnose corrupt / unknown key type entries by
showing their decimal value, correlating with the definitions in
keyer.go.
* cmd/stindex: Add missing KeyType values in stindex dump code.
Recently added DB key prefixes KeyTypeBlockListMap and KeyTypeVersion
were unknown to the stindex dumping tool. Add basic parsing to dump
their key structure.
This adds indirection of large version vectors in the same manner as we
already to block lists. The effect is the same: less duplicated data in
some situations.
To mitigate the impact for when this indirection
wouldn't be needed I've added an indirection cutoff for both blocks and
the new version vector stuff: we don't do the indirection at all for
small block lists or small version vectors, instead storing it directly
like we used to do. This is faster for small files and small setups.
Storing assets as []byte requires every compiled-in asset to be copied
into writable memory at program startup. That currently takes up 1.6MB
per syncthing process. Strings stay in the RODATA section and should be
shared between processes running the same binary.
