`BlockPullOrder`, `DisableFsync` and `MaxConcurrentWrites` folder
options to the configuration schema.

v1.5.0

This release changes the default location for the index database under
some circumstances. Two new flags can also be used to affect the
location of the configuration (`-config`) and database (`-data`)
separately. The old `-home` flag is equivalent to setting both of these
to the same directory. When no flags are given the following logic is
used to determine the data location:

- If a database exists in the old default location, that location is
  still used. This means existing installations are not affected by this
  change.
- If `$XDG_DATA_HOME` is set, use `$XDG_DATA_HOME/syncthing`.
- If `~/.local/share/syncthing` exists, use that location.
- Use the old default location.

This logic is used on non-Windows, non-Mac platforms only. On Windows
and Mac the logic is unchanged.

Bugfixes:

- syncthing#3808: gui: Number of days must be number flashes red then disappears
- syncthing#5809: stdiscosrv failed to load keypair without proper error message
- syncthing#6410: Wrong 30-days-interval in staggered versioning
- syncthing#6430: Incorrect out-of-sync/locally changed status indication on folders
- syncthing#6436: Revert Local Changes red button does not work correctly
- syncthing#6440: Doesn't run monitor process when started with STNORESTART=1
- syncthing#6450: LDAP auth doesn't handle LDAPS with certificate validation
- syncthing#6487: Scan problem within single unignored subdirectory prevents bidirectional sync

Enhancements:

- syncthing#4924: Move index db to $XDG_DATA_HOME/syncthing/
- syncthing#5376: Improve LDAP authentication
- syncthing#6384: Do auto upgrades early and synchronously on startup
- syncthing#6416: Improve device status for "unused" devices
- syncthing#6432: Deleted file that existed locally only reported as locally changed
- syncthing#6437: Don't start browser when restarting after upgrade

Other issues:

- syncthing#6471: Windows exe isn't properly version tagged
