Add PSM value to the RFCOMM service so that the host knows what PSM to use on channels when trying to access it.

Reduce the size of the attribute search list from 15 ranges to 8 to save RAM.

Fix byte ordering of UUIDs in the SDP server - host can now successfully pair to the Bluetooth device and discover the exposed Serial Port Profile RFCOMM service.

The SDP UUID lists should be searched and ALL UUIDs matched for a record to be retrieved, not partial matches. Change the SDP code so that the entire list must be matched against a service attribute table's contents before it is returned.

Change matching algorithm so that it recursively searches through the entire attribute table, and not just pre-specified sequence attributes.

Add browse lists and proper descriptions to the Serial Port service.

Add L2CAP service attribute table. Fix up ProtocolDescriptorList attributes, and add macros for used UUIDs to reduce typing and make the code easier to read.

Remove incorrect Language ID offset attribute from the SDP server - client assumes 0x0100 offset for primary language anyway, and the format of the offset was incorrect anyway.

Much faster attribute range lookup - look through short list of attributes and compare to range, rather than looking up by each possible value within the range.

Cleanups to SDP code. Add missing RFCOMM language base ID offset attribute. Fix incorrect definition of the SWAPENDIAN_32() macro.
