Dear all,

I recently met an alignment trap in hcid.
Some device sent me an sdp request and the answer had to be fragmented 
because the device reception buffer was very small.
After that i saw alignment trap.
The last trace I saw was : Continuation state size: 8
The trace is located at sdpd/request.c : static sdp_cont_state_t 
*sdp_cstate_get(uint8_t *buffer)
This function returns an unaligned pointer.

I think this patch is ok, but it has never been tested, and possibly 
other problems are hidden behind.
Instead of returning an unaligned pointer, the patch allocates a buffer.

To test it, i could build a bluez with small sdp reception buffer and 
ask an arm to give me fragmented reply.
This would save me some time if someone could tell me where to change 
this value...

BR,
Frederic
