[PATCH v2 0/3] Enable WFD Sub-elements settings through DBus

v2: Added the missing Signed-off-by in the commit messages

Hi,

This is a quick patch-set to support setting WFD sub-elements through DBus,
which was only possible through the socket interface before.

Difference here is that you set the whole sub-elements you want at once, through
a byte array which represent the WFD IEs. It's easier to have one property to get/set
this way rather than having specific methods to add one sub-element per sub-element.
This also follows what exists for Peer objects where you get their WFD IEs at once.
