...rather than relying on cmake magic

Task #2259

The server keeps the mtime and etag anyway.
And changing the mtime also changes the etag and so make other clients re-download
the file instead of detecting the move

...rather than relying on cmake magic

The SocketAPI sends status updates for files without being asked for.
And in order to not draw the emblem again if it had not changed, the
state is compared before calling add_emblem

This avoids a warning.

Set that to be accessible by the owner only.

Also, use the appname to find the correct branded icons.

The two files are from the fork from
https://github.com/jdiehl/CocoaAsyncSocket/tree/socketUN
It supports unix domain sockets.

Relates issue #2189

This make no sens to just set the pause config flag here. It make selective sync to mark
the folder as posed on restart

This save some time when selective sync deselected a large tree

It was renamed from white list to black list long ago
