Without this the summary service doesn't know to recalculate completion
percentage for remote devices when DownloadProgress messages come in.
That means that completion percentage isn't updated in the GUI while
transfers of large files are ongoing. With this change, it updates
correctly.

I think this better reflects what it means. Also tweaks the verbose
format to be more like our other things and lightly refactors the code
to not have the boolean and include the folder in the event.

The old usage pattern was to create a Walker with a bunch of attributes,
then call Walk() on it and nothing else. This extracts the attributes
into a Config struct and exposes a Walk(cfg Config) method instead, as
there was no reason to expose the state-holding walker type.
Also creates a few no-op implementations of the necessary interfaces
so that we can skip nil checks and simiplify things here and there.
Definitely look at this diff without whitespace.

When doing prefix scans in the database, "foo" should not be considered
a prefix of "foo2". Instead, it should match "foo" exactly and also
strings with the prefix "foo/". This is more restrictive than what the
standard leveldb prefix scan does so we add some code to enforce it.
Also exposes the initialScanCompleted on the rwfolder for testing, and
change it to be a channel (so we can wait for it from another
goroutine). Otherwise we can't be sure when the initial scan has
completed, and we need to wait for that or it might pick up changes
we're doing at an unexpected time.

The VersioningConfig change is because it defaults to nil but gets
deserialized to map[string]string{}. Now prepare() enforces a single
representation of the empty map.

1. Removes separate relay lists and relay clients/services, just makes it a listen address
2. Easier plugging-in of other transports
3. Allows "hot" disabling and enabling NAT services
4. Allows "hot" listen address changes
5. Changes listen address list with a preferable "default" value just like for discovery
6. Debounces global discovery announcements as external addresses change (which it might alot upon starting)
7. Stops this whole "pick other peers relay by latency". This information is no longer available,
but I don't think it matters as most of the time other peer only has one relay.
8. Rename ListenAddress to ListenAddresses, as well as in javascript land.
9. Stop serializing deprecated values to JSON

Previously the code failed in that it would return top-level plus a sub,
i.e. ["", "foo"], and it would consider "usr/lib" a prefix of
"usr/libexec" which it is not.
Fixes#2151.
Since Walk.walkAndHashFiles ignores .stfolder and .stignore, they will
never be found by fs.Get(protocol.LocalDeviceID, sub) in
Model.internalScanFolder. As a result, when asked to scan those subs
we end up scanning the whole folder.
This reverts the change introduced in 9b9fe0d Reduce scanning effort.
That commit caused us to automatically ignore the basename of the
specified subs and instead scan closest known root folder. For
example, in a folder that looks like:
Sync/
├── 00
│ ├── one
│ ├── three
│ └── two
├── 01
│ ├── one
│ ├── three
│ └── two
├── 02
│ ├── one
│ ├── three
│ └── two
└── one
calling '/rest/db/scan?folder=default&sub=01' called filepath.Walk on
the whole Sync/ folder instead of just the desired subfolder. This
contradicts the scan behavior promised by the documentation.
This is related to #2151.
Checks the existing blocks that can be reused when downloading a file so
that it only requires the space corresponding to the missing blocks.
This will prevent syncthing from claiming the folder doesn't have enough
space when resuming download of large files after they have been
partially downloaded.
We're going to need the db.Instance to keep some state, and for that to
work we need the same one passed around everywhere. Hence this moves the
leveldb-specific file opening stuff into the db package and exports the
dbInstance type.
Overwriting configuration files is likely to happen if a
user syncs their home directories across computers. In this
case, the biggest risk is that all nodes will end up with
the same certificate and thus Device ID.
When the model prepares a folder for syncing, it checks to
see if the configuration files this instance is using are
getting synced. If the are getting synced, and they aren't
getting ignored, a warning is emitted. The model is used
so that when a new folder is added dynamically, a warning
is also emitted.
This will not prevent a user from shooting themselves in
the foot, and will not cover all cases (e.g. symlinks).
It should provide _something_ for many users in this
situation to go on, though.
This implements a new debug/trace infrastructure based on a slightly
hacked up logger. Instead of the traditional "if debug { ... }" I've
rewritten the logger to have no-op Debugln and Debugf, unless debugging
has been enabled for a given "facility". The "facility" is just a
string, typically a package name.
This will be slightly slower than before; but not that much as it's
mostly a function call that returns immediately. For the cases where it
matters (the Debugln takes a hex.Dump() of something for example, and
it's not in a very occasional "if err != nil" branch) there is an
l.ShouldDebug(facility) that is fast enough to be used like the old "if
debug".
The point of all this is that we can now toggle debugging for the
various packages on and off at runtime. There's a new method
/rest/system/debug that can be POSTed a set of facilities to enable and
disable debug for, or GET from to get a list of facilities with
descriptions and their current debug status.
Similarly a /rest/system/log?since=... can grab the latest log entries,
up to 250 of them (hardcoded constant in main.go) plus the initial few.
Not implemented in this commit (but planned) is a simple debug GUI
available on /debug that shows the current log in an easily pasteable
format and has checkboxes to enable the various debug facilities.
The debug instructions to a user then becomes "visit this URL, check
these boxes, reproduce your problem, copy and paste the log". The actual
log viewer on the hypothetical /debug URL can poll regularly for new log
entries and this bypass the 250 line limit.
The existing STTRACE=foo variable is still obeyed and just sets the
start state of the system.
An error on opening .stignore will satisfy os.IsNotExist() and not be
reported. Other errors will be reported and stop the folder, including
is-not-exist errors from #include as these are passed through fmt.Errorf.
Also fixes minor issue where we would not print cause of folder stopping
to the log.
Also fixes minor issue with capitalization of errors.
Instead, make sure we do the check as part of CheckFolderHealth before
pulling, and individually per file to try to not run out of space at
that stage.
(The latter is far from fool proof as we may pull lots of stuff in
parallell, but it's worth a try.)
This fixes a corner case I discovered in the symlink branch, where we
unexpectedly succeed in "replacing" an entire non-empty directory tree
with a file or symlink. This happens when archiving is in use, as we
then just move the entire tree away into the archive. This is wrong as
we should just archive files and fail on non-empty dirs in all cases.
New handling first checks what the (old) thing is, and if it's a
directory or symlink just does the delete, otherwise does conflict
handling or archiving as appropriate.
The number of copiers and pullers is set to default at config loading
time, but the new folder configuration doesn't pass through config
loading so we start up with 0 copiers and 0 pullers and hence get stuck.
I moved the default handling to the puller itself instead. I think this
way is also cleaner as we get to keep the 0 in the config and the puller
gets to decide the defaults on it's own.
