49910a1d85 lib/config, cmd/syncthing: Enforce localhost only connections
When the GUI/API is bound to localhost, we enforce that the Host header
looks like localhost. This can be disabled by setting
insecureSkipHostCheck in the GUI config.

46a143e80e lib/model: Handle deleted-then-ignored files (fixes #3502)
When files that were previously marked as deleted became ignored, we
used to do nothing at all. This changes that behavior to set the Invalid
bit (that we should rename to Ignored). This then becomes an update to
other devices that they should not trust our knowledge about the file in
question.

Read this diff without whitespace...

Tested by
- creating a bunch of files on s1
- letting them sync to s2
- shutting down s2
- deleting the files on s1 and rescanning
- adding the files to .stignore on s1 and rescanning
- starting up s2 and letting it sync
- observing the files are not deleted on s2, and it considers itself up
  to date.

5b37d0356c lib/model, gui: Correct completion percentages when there are lots of deletes (fixes #3496)
We used to consider deleted files & directories 128 bytes large. After
the delta indexes change a bug slipped in where deleted files would be
weighted according to their old non-deleted size. Both ways are
incorrect (but the latest change made it worse), as if there are more
files deleted than remaining data in the repo the needSize can be
greater than the globalSize, resulting in a negative completion
percentage.

This change makes it so that deleted items are zero bytes large, which
makes more sense. Instead we expose the number of files that we need to
delete as a separate field in the Completion() result, and hack the
percentage down to 95% complete if it was 100% complete but we need to
delete files. This latter part is sort of ugly, but necessary to give
the user some sort of feedback.

0b1475169f lib/model: Correct virtual mtime handling (fixes #3516)
We previously set the mtime on the temp file, and then renamed it to the
real path. Unfortunately that means we'd save the real timestamp under
the under the temp name ".syncthing.foo.tmp" when the actual file that
we will look up on the next scan is "foo". This moves the Chtimes later,
ensuring that it gets recorded correctly under the right name.

e52be3d83e lib/connections, lib/model: Refactor connection close handling (fixes #3466)
So there were some issues here. The main problem was that
model.Close(deviceID) was overloaded to mean "the connection was closed
by the protocol layer" and "i want to close this connection". That meant
it could get called twice - once *to* close the connection and then once
more when the connection *was* closed.

After this refactor there is instead a Closed(conn) method that is the
callback. I didn't need to change the parameter in the end, but I think
it's clearer what it means when it takes the connection that was closed
instead of a device ID. To close a connection, the new close(deviceID)
method is used instead, which only closes the underlying connection and
leaves the cleanup to the Closed() callback.

I also changed how we do connection switching. Instead of the connection
service calling close and then adding the connection, it just adds the
new connection. The model knows that it already has a connection and
makes sure to close and clean out that one before adding the new
connection.

To make sure to sequence this properly I added a new map of channels
that get created on connection add and closed by Closed(), so that
AddConnection() can do the close and wait for the cleanup to happen
before proceeding.

ea87bcefd6 lib/protocol, lib/model: Implement high precision time stamps (fixes #3305)
This adds a new nanoseconds field to the FileInfo, populates it during
scans and sets the non-truncated time in Chtimes calls.

The actual file modification time is defined as modified_s seconds +
modified_ns nanoseconds. It's expected that the modified_ns field is <=
1e9 (that is, all whole seconds should go in the modified_s field) but
not really enforced. Given that it's an int32 the timestamp can be
adjusted += ~2.9 seconds by the modified_ns field...

ffe7a2fcd7 cmd/syncthing, lib/config: Enable HTTP CPU/heap profile collection for users
This adds a config to enable debug functions on the API server, which is
by default disabled. When enabled, the /rest/debug things become
available and become available without requiring a CSRF token (although
authentication is required if configured).

We also add a new endpoint /rest/debug/cpuprof?duration=15s (with the
duration being configurable, defaulting to 30s). This runs a CPU profile
for the duration and returns it as a file. It sets headers so that a
browser will save the file with an informative name.

The same is done for heap profiles, /rest/debug/heapprof, which does not
take any parameters.

The purpose of this is that any user can enable debugging under
advanced, then point their browser to the endpoint above and get a file
that contains a CPU or heap profile we can use, with the filename
telling us what version and architecture the profile is from.

On the command line, this becomes

    curl -O -J http://localhost:8082/rest/debug/cpuprof?duration=5s
    curl: Saved to filename
    'syncthing-cpu-darwin-amd64-v0.14.3+4-g935bcc0-110307.pprof'

2a6f164923 lib/scanner: When scanning a file, stick to the size given by Lstat (fixes #3440)
Otherwise if the file grows during scanning the block list will be out
of sync with the stated size and things get confused. We could fixup the
size afterwards based on the block list, but then we might see other
inconsistencies as the mtime should have changed to reflect the new size
etc. Better stick to the original state and let the next scan pick up
the change.

6ed22d0885 lib/model: Stricter temporary file permissions
We could have a file to sync with permissions rw------- but we'd create
the temp file with rw-rw-rw- minus umask, usually rw-r--r--. This
potentially exposes private data while the file is being synced.

Similarly, when ignorePerms was set and we were reusing a temp files we
would set the permissions to rw-r--r-- explicitly, potentially
overriding a strict umask that would otherwise have had the file be
rw-------.

The previous commit loosened the locking around database updates.
Apparently that was not fine - what happens is that parallell updates

7b7e35d339 lib/protocol: Hello message length is an int16
It used to be an int32, but that's unnecessary and the spec now says
int16. Also relaxes the size requirement to that which fits in a signed
int16 instead of limiting to 1024 bytes, to allow for future growth.

e440d30028 lib/protocol: Allow unknown message types
This lets us add message types in the future, for authentication or
other purposes, without completely breaking old clients. I see this as
similar behavior to adding fields to messages - newer clients must
simple be aware that older ones may ignore the message and act
accordingly.

44d30c83bf lib/config, cmd/syncthing: Handle committing configuration better (fixes #3077)
This slightly changes the interface used for committing configuration
changes. The two parts are now:

 - VerifyConfiguration, which runs synchronously and locked, and can
   abort the config change. These callbacks shouldn't *do* anything
   apart from looking at the config changes and saying yes or no. No
   change from previously.

 - CommitConfiguration, which runs asynchronously (one goroutine per
   call) *after* replacing the config and releasing any locks. Returning
   false from these methods sets the "requires restart" flag, which now
   lives in the config.Wrapper.

This should be deadlock free as the CommitConfiguration calls can take
as long as they like and can wait for locks to be released when they
need to tweak things. I think this should be safe compared to before as
the CommitConfiguration calls were always made from a random background
goroutine (typically one from the HTTP server), so it was always
concurrent with everything else anyway.

Hence the CommitResponse type is gone, instead you get an error back on
verification failure only, and need to explicitly check
w.RequiresRestart() afterwards if you care.

As an added bonus this fixes a bug where we would reset the "requires
restart" indicator if a config that did not require restart was saved,
even if we already were in the requires-restart state.

A random "instance ID" is generated on each start of the local discovery

new instance ID we treat is a new device and respond with an
announcement of our own. Hence devices get to know each other quickly on
restart.

223a835f33 lib/discover: Respect the listen address scheme (fixes #3346)
This is a supplement patch to commit a58f69b which only fixed global
discovery. This patch adds the missing parts for the local discovery.

If the listen address scheme is set to tcp4:// or tcp6:// and no
explicit host is specified, an address should not be considered if the
source address does not match this scheme.

This prevents invalid URIs like tcp4://<IPv6 address>:<port> or tcp6://<IPv4
address>:<port> for local discovery.
