dav: Increase max number of connections to prevent lockups
Currently, the default value of max-conns-per-host libsoup property is used, which causes dav backend lockups if two files are opened. I don't see any easy solution how to prevent lockups, but we can definitely reduce the chance of them by increasing max-conns properties. Much bigger values are used by browsers nowadays. Hope that 32 is big enough for regular use cases and small enough to not flood a server and not block too much file descriptors...
