d6fbfc3545 lib/fs, lib/model, lib/scanner: Make scans cancellable (fixes #3965)
The folder already knew how to stop properly, but the fs.Walk() didn't
and can potentially take a very long time. This adds context support to
Walk and the underlying scanning stuff, and passes in an appropriate
context from above. The stop channel in model.folder is replaced with a
context for this purpose.

To test I added an infiniteFS that represents a large amount of data
(not actually infinite, but close) and verify that walking it is
properly stopped. For that to be implemented smoothly I moved out the
Walk function to it's own type, as typically the implementer of a new
filesystem type might not need or want to reimplement Walk.

It's somewhat tricky to test that this actually works properly on the
actual sendReceiveFolder and so on, as those are started from inside the
model and the filesystem isn't easily pluggable etc. Instead I've tested
that part manually by adding a huge folder and verifying that pause,
resume and reconfig do the right things by looking at debug output.

488444354b lib/db: Don't panic
So, when first implementing the database layer I added panics on every
unexpected error condition mostly to be sure to flush out bugs and
inconsistencies. Then it became sort of standard, and we don't seem to
have many bugs here any more so the panics are usually caused by things
like checksum errors on read. But it's not an optimal user experience to
crash all the time.

Here I've weeded out most of the panics, while retaining a few "can't
happen" ones like errors on marshalling and write that we really can't
recover from.

For the rest, I'm mostly treating any read error as "entry didn't
exist". This should mean we'll rescan the file and correct the info (if
scanning) or treat it as a new file and do conflict handling (when
pulling). In some cases things like our global stats may be slightly
incorrect until a restart, if a database entry goes suddenly missing
during runtime.

All in all, I think this makes us a bit more robust and friendly without
introducing too many risks for the user. If the database is truly toast,
probably many other things on the system will be toast as well...

e9f05d138f lib/db, lib/model: Always use reasonable sized batches (fixes #2250, fixes #4112)
Harmonize how we use batches in the model, using ProtoSize() to judge
the actual weight of the entire batch instead of estimating. Use smaller
batches in the block map - I think we might have though that batch.Len()
in the leveldb was the batch size in bytes, but it's actually number of
operations.

6b188ebcf3 lib/model: Mark initial scan as finished even if failed and refactor (fixes #4103)
The mechanism to disallow manual scans before the initial scan completed
(#3996) , had the side effect, that if the initial scan failed, no further
scans are allowed. So this marks the initial scan as finished regardless of
whether it succeeded or not.

There was also redundant code in rofolder and a pointless check for folder
health in scanSubsIfHealthy (happens in internalScanFolderSubdirs as well).
This also moves logging from folder.go to ro/rw-folder.go to include the
information about whether it is send-only or send-receive

d48e46a29c cmd/syncthing: Allow custom event subscriptions (fixes #1879)
This adds a parameter "events" to the /rest/events endpoint. It should
be a comma separated list of the events the consumer is interested in.
When not given it defaults to the current set of events, so it's
backwards compatible.

The API service then manages subscriptions, creating them as required
for each requested event mask. Old subscriptions are not "garbage
collected" - it's assumed that in normal usage the set of event
subscriptions will be small enough. Possibly lower than before, as we
will not set up the disk event subscription unless it's actually used.

da34f27546 gui, lib/config, lib/model: Allow absolute values for minimum disk free space (fixes #3307)
This deprecates the current minDiskFreePct setting and introduces
minDiskFree. The latter is, in it's serialized form, a string with a
unit. We accept percentages ("2.35%") and absolute values ("250 k", "12.5
Gi"). Common suffixes are understood. The config editor lets the user
enter the string, and validates it.

We still default to "1 %", but the user can change that to an absolute
value at will.

c5e0c47989 lib/connections, lib/model, gui: Specify allowed networks per device (fixes #219)
This adds a new config AllowedNetworks per device, which when set should
contain a list of network prefixes (192.168.0.0/126 etc) that are
allowed for the given device. The connection service will not attempt
connections to addresses outside of the given networks and incoming
connections will be rejected as well.

I've added the config to the normal device editor and shown it (when
set) in the device summary on the main screen.

There's a unit test for the IsAllowedNetwork method, I've done some
manual sanity testing on top of that.

4253f22680 lib/scanner: Use fs.Filesystem for all operations
One more step on the path of the great refactoring. Touches rwfolder a
little bit since it uses the Lstat from fs as well, but mostly this is
just on the scanner as rwfolder is scheduled for a later refactor.

There are a couple of usages of fs.DefaultFilesystem that will in the
end become a filesystem injected from the top, but that comes later.

89f8be40c6 lib/model: Use ignore patterns in remote completion calculation
Basically, if we don't care about the sync status of the file we should
not tag someone else out of sync because they don't have the latest
version. This solves *my* "Syncing - 100%" scenario at least.

The reason this happens seems to be like this, in my situation. I have
three devices, connected in a "line": A-B-C. A is a Mac and litters
.DS_Store files everywhere. I've ignored these, but some escaped into
the folders before I did so. I've also ignored them on B and C but at
different stages. B was flagging C as out of sync, because at the point
the ignores were introduced C had a lower version of .DS_Store than A.
Now none of them are sending updates about it any more since it's
ignored...

c4ba580cbb all: Remove symlink support on Windows, SymlinksEnabled config
After this change,

- Symlinks on Windows are always unsupported. Sorry.

- Symlinks are always enabled on other platforms. They are just a small
  file like anything else. There is no need to special case them. If you
  don't want to sync some symlinks, ignore them.

- The protocol doesn't differentiate between different "types" of
  symlinks. If that distinction ever does become relevant the individual
  devices can figure it out by looking at the destination when they
  create the link.

It's backwards compatible in that all the old symlink types are still
understood to be symlinks, and the new SYMLINK type is equivalent to the
old SYMLINK_UNKNOWN which was always a valid way to do it.

fdcbd54cd7 lib/events: Be more resilient against dropping events (fixes #3952)
Instead of just immediately dropping the event if the subscription isn't
ready to receive it, give it 15 ms to catch up. The value 15 ms is
grabbed out of thin air - it just seems reasonable to me.

The timer juggling makes the event send pretty much exactly twice as
slow as it was before, but we're still under a microsecond. I think it's
negligible compared to whatever event that just happened that we're
interested in logging (usually a file operation of some kind).
