Log:
 The wimax plugin primarily uses tvb_get_ptr buffer accesses instead of the
 safe accessor functions, and it's all done via scary bit-twiddling macros to
 boot.
 
 Create the macros TVB_NIB_WORD and TVB_NIB_NIBBLE that (should) behave just
 like the raw-pointer NIB_WORD and NIB_NIBBLE macros, except using the safe tvb
 functions instead.
 
 Replace two instances with the safe versions, which fixes an out-of-bounds
 access caught by my valgrind fuzzer. If this doesn't break anything then we
 should probably do a wholesale replacement at some point, but I'm not feeling
 that adventurous at the moment.
