[PATCH 0/1 rev2] Add SDP registration of Primary Services

This is a fully merged patch to take into account Claudio's changes
to Device Name Characteristic etcetra.

Otherwise:

This addresses Anderson's issue with the SDP registration. It maintains
the prior APIs and adds a couple which can be called any time after
a complete Primary Service has been inserted into the attribute database.

This allows the attrib-server user to pick and choose the services he
wants to expose to BR/EDR devices, as opposed to LE only devices. It also
gives a mechanism to remove the SDP record from the SDP db.

It also has improved naming (attrib_*) to tie all the parts together.
