This adds support for syncing extended attributes on supported
filesystem on Linux, macOS, FreeBSD and NetBSD. Windows is currently
excluded because the APIs seem onerous and annoying and frankly the uses
cases seem few and far between. On Unixes this also covers ACLs as those
are stored as extended attributes.
Similar to ownership syncing this will optional & opt-in, which two
settings controlling the main behavior: one to "sync" xattrs (read &
write) and another one to "scan" xattrs (only read them so other devices
can "sync" them, but not apply any locally).

This replaces old style errors.Wrap with modern fmt.Errorf and removes
the (direct) dependency on github.com/pkg/errors. A couple of cases are
adjusted by hand as previously errors.Wrap(nil, ...) would return nil,
which is not what fmt.Errorf does.
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...).
Staggered File Versioning used to have its own cleanInterval that
controlled how often file versions were cleaned. Nowadays, there is a
seperate setting called cleanupIntervalS responsible for the cleanup,
which applies to all File Versioning (except External). Thus, remove the
unneeded code and don't set the param up on new folders anymore.

* cmd/syncthing: Remove unnecessary function arguments.
The openGUI() function does not need a device ID to work, and there is
only one caller anyway which uses EmptyDeviceID.
The loadOrDefaultConfig() function is always called with the same
dummy values.
* cmd/syncthing: Avoid misleading info messages from monitor process.
In order to check whether panic reporting is enabled, the monitor
process utilizes the loadOrDefaultConfig() function. In case there is
no config file yet, info messages may be logged during creation if the
config Wrapper, which is discarded immediately after.
Stop using the DefaultConfig() utility function from lib/syncthing and
directly generate a minimal config instead to avoid these.
Add comments to loadOrDefaultConfig() explaining its limited purpose.
* cmd/syncthing/generate: Always write updated config file.
Previously, an existing config file was left untouched unless either
of the --gui-user or --gui-password options was given. Remove that
condition and simplify the checking code.
* lib/config: Factor out ProbeFreePorts().
* cmd/syncthing: Add option --skip-port-probing.
Applies to both the "generate" and "serve" subcommands, as well as the
deprecated --generate option, just as the --no-default-folder flag.
- In the few places where we wrap errors, use the new Go 1.13 "%w"
construction instead of %s or %v.
- Where we create errors with constant strings, consistently use
errors.New and not fmt.Errorf.
- Remove capitalization from errors in the few places where we had that.
Adds a new folder state "Waiting to Sync" in the same vein as the
existing "Waiting to Scan". This vastly improves performances in the
rare cases when there are lots and lots of folders operating.
* lib/ur: Implement crash (panic) reporting (fixes#959)
This implements a simple crash reporting method. It piggybacks on the
panic log files created by the monitor process, picking these up and
uploading them from the usage reporting routine.
A new config value points to the crash receiver base URL, which defaults
to "https://crash.syncthing.net/newcrash" (following the pattern of
"https://data.syncthing.net/newdata" for usage reports, but allowing us
to separate the service as required).
* cleanup Fatal in lib/config/config.go
* cleanup Fatal in lib/config/folderconfiguration.go
* cleanup Fatal in lib/model/model.go
* cleanup Fatal in cmd/syncthing/monitor.go
* cleanup Fatal in cmd/syncthing/main.go
* cleanup Fatal in lib/api
* remove Fatal methods from logger
* lowercase in errors.Wrap
* one less channel
Two small behavior changes: don't "charge" the data to the global rate
limit until it's been accepted by the device specific limiter, and fix
the send/recv direction in the log print on per device rate limits.
This adds one new feature, that discovery servers can have ?nolookup to
be used only for announces. The default set of discovery servers is
changed to:
- discovery.s.n used for lookups. This is dual stack load balanced over
all discovery servers, and returns both IPv4 and IPV6 results when they
exist.
- discovery-v4.s.n used for announces. This has IPv4 addresses only and
the discovery servers will update the unspecified address with the IPv4
source address, as usual.
- discovery-v6.s.n which is exactly the same for IPv6.
