[PATCH 0/3] Modifications composed during UPF38

[Brian Gix <bgix@codeaurora.org>]

The major change in these patches is to register Primary Services
into the SDP databases as required when registering them
into the attrib-server's database. The Core v4.0 specification
indicates that the only valid/foolproof way for a BR/EDR
client to query a server for Primary Services is to do so via
an SDP query. This is from Core v4.0, Vol 3, Part G, Sec 4.4:

"GATT service discovery over BR/EDR transport will list services that only run
over an LE transport and therefore only SDP service discovery shall be used
on BR/EDR."

This also means that there can be "LE Only" primary services that do NOT
need to be in the SDP database, so if a valid range is not specified
when registering a Primary Service, it will be omitted from SDP, and
only appear when performing a GATT based Primary Service Discover.

Also -- The ATT_UUID we were using was incorrect, and I extended the
functionality of the gatttool to allow for listening without sending
anything, and ability to perform both a char-write and char-cmd.
