Lynne 56b85b689d aacdec_ac: fix signed overflow in ff_aac_ac_update_context()
The issue is that state->cur[] is 8-bits, but a+b+1 can overflow
before being clipped to 0xF in the following line, causing an incorrect
state to be saved for the next symbol.

This solves numerous bitstream desyncs, particularly when coefficients
with magnitude greater than 127 are sent.
