[PATCH] Changes in HDP API.

[Jose Antonio Santos Cadenas <santoscadenas@gmail.com>]

Now the connection is made directly to a device and bluetoothd daemon
guess the PSM connection and the MDEPID based on the data get from the
SDP record.

Also a property that indicates the MainChannel is added to the
HealthDevice object.
