cmd/strelaysrv: Add optional auth token (fixes #3987) (#8561)
* implement authentication via token for relaysrv

Make replaysrv check for a token before allowing clients to
join. The token can be set via the replay-uri.

* fix formatting

* key composite literal

* do not error out if auth material is provided but not needed

* remove unused method receiver

* clean up unused parameter in functions

* cleaner token handling, disable joining the pool if token is set.

* Keep backwards compatibility with older clients.

In prior versions of the protocol JoinRelayRequest did not have a
token field. Trying to unmarshal such a request will result in
an error. Return an empty JoinRelayRequest, that is a request
without token, instead.

all: Add build constants for runtime.GOOS comparisons (#8442)
all: Add package runtimeos for runtime.GOOS comparisons

I grew tired of hand written string comparisons. This adds generated
constants for the GOOS values, and predefined Is$OS constants that can
be iffed on. In a couple of places I rewrote trivial switch:es to if:s,
and added Illumos where we checked for Solaris (because they are
effectively the same, and if we're going to target one of them that
would be Illumos...).

cmd/strelaysrv, cmd/strelaypoolsrv: Sanitize query strings (fixes #8314) (#8315)
Use the proper encoding function in the relay server when constructing
the URL. In the pool server, parse and re-encode the query values to
sanitize whatever the client sent.

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.

build, lib/build: Build faster (#6538)
This changes the build script to build all the things in one go
invocation, instead of one invocation per cmd. This is a lot faster
because it means more things get compiled concurrently. It's especially
a lot faster when things *don't* need to be rebuilt, possibly because it
only needs to build the dependency map and such once instead of once per
binary.

In order for this to work we need to be able to pass the same ldflags to
all the binaries. This means we can't set the program name with an
ldflag.

When it needs to rebuild everything (go clean -cache):

    ( ./old-build -gocmd go1.14.2 build all 2> /dev/null; )  65.82s user 11.28s system 574% cpu 13.409 total
    ( ./new-build -gocmd go1.14.2 build all 2> /dev/null; )  63.26s user 7.12s system 1220% cpu 5.766 total

On a subsequent run (nothing to build, just link the binaries):

    ( ./old-build -gocmd go1.14.2 build all 2> /dev/null; )  26.58s user 7.53s system 582% cpu 5.853 total
    ( ./new-build -gocmd go1.14.2 build all 2> /dev/null; )  18.66s user 2.45s system 1090% cpu 1.935 total

all: Update certificate lifetimes (fixes #6036) (#6078)
This adds a certificate lifetime parameter to our certificate generation
and hard codes it to twenty years in some uninteresting places. In the
main binary there are a couple of constants but it results in twenty
years for the device certificate and 820 days for the HTTPS one. 820 is
less than the 825 maximum Apple allows nowadays.

This also means we must be prepared for certificates to expire, so I add
some handling for that and generate a new certificate when needed. For
self signed certificates we regenerate a month ahead of time. For other
certificates we leave well enough alone.

do. Conversely the lib/build package wasn't aware there might be other
users and hard coded the program name - now it's set by the build

f1a7dd766e all: Add comment to ensure correct atomics alignment (fixes #5813)
Per the sync/atomic bug note:

> On ARM, x86-32, and 32-bit MIPS, it is the caller's
> responsibility to arrange for 64-bit alignment of 64-bit words
> accessed atomically. The first word in a variable or in an
> allocated struct, array, or slice can be relied upon to be
> 64-bit aligned.

All atomic accesses of 64-bit variables in syncthing code base are
currently ok (i.e they are all 64-bit aligned).

Generally, the bug is triggered because of incorrect alignement
of struct fields. Free variables (declared in a function) are
guaranteed to be 64-bit aligned by the Go compiler.

To ensure the code remains correct upon further addition/removal
of fields, which would change the currently correct alignment, I
added the following comment where required:

     // atomic, must remain 64-bit aligned

See https://golang.org/pkg/sync/atomic/#pkg-note-BUG.

cmd/*, lib/tlsutil: Refactor TLS stuff (fixes #5256) (#5276)
This changes the TLS and certificate handling in a few ways:

- We always use TLS 1.2, both for sync connections (as previously) and
  the GUI/REST/discovery stuff. This is a tightening of the requirements
  on the GUI. AS far as I can tell from caniusethis.com every browser from
  2013 and forward supports TLS 1.2, so I think we should be fine.

- We always greate ECDSA certificates. Previously we'd create
  ECDSA-with-RSA certificates for sync connections and pure RSA
  certificates for the web stuff. The new default is more modern and the
  same everywhere. These certificates are OK in TLS 1.2.

- We use the Go CPU detection stuff to choose the cipher suites to use,
  indirectly. The TLS package uses CPU capabilities probing to select
  either AES-GCM (fast if we have AES-NI) or ChaCha20 (faster if we
  don't). These CPU detection things aren't exported though, so the tlsutil
  package now does a quick TLS handshake with itself as part of init().
  If the chosen cipher suite was AES-GCM we prioritize that, otherwise we
  prefer ChaCha20. Some might call this ugly. I think it's awesome.
