Subject: [PATCH] Add support for the new OSTC3 bailout event.

With the exception of the different event mask (single byte 0x80 vs two
byte 0x0100), the OSTC3 bailout event is identical to the OSTC2 variant.
Just as before, the new bailout event is reported to the application as
a normal gas change event.
