TI BTS for hciattach

This proposed patch implements the TI BTS (Bluetooth script) mechanism. I have attached the diff and new files to be built along with hciattach. I have also attached a sample BTS file (the one that goes along with the BRF6150 plus firmware, as found in the iPAQ hx4700). The code is a bit chatty (prints BTS comment lines), but provides feedback as to what is being done with the chip. Comments / Suggestions welcome. Example usage:

hciattach -S /etc/bluetooth/TIInit_3.2.26.bts ttyS1 texas

Sample output (comments come from bts file):

TI module LMP version : 0x02
TI module LMP sub-version : 0x0d1a
Loading BTS script version 1

Hi Todd,

is it possible to get a development kit with the BRF6150 from TI? I like to test this new code.

Do we get the full specification of BTS? I think we need to rewrite some parts of the TI code. I don't like the coding style and parts of it look too much like crappy Windows code.

Regards

Marcel
