    sigcomp: Add buffer check to STATE-ACCESS
    
    Two conditions were not checked, state_length == 0 && state_begin != 0
    and the boundaries of the state buffer. The former is not a big deal,
    but the second issue causes a buffer overrun (detected by ASAN).
    
    The buffer size is supposed to be stored in the state buffer, that was
    not the case for the initial two SIP SDP and Presence state buffers.
    Fix a typo for presence_buf zero-ing while at it.
