  Log:
  performance enhancement to proto.c
  
  Removed the GMemChunk used to allocate/free field_info structures
  and used a free list to store the freed structs until they are allocated again.
  
  Ethereal will allocate more field_info structs as it needs to but never free them. Instead the are just placed in a cheap and fast free list so that if we
  want to use the struct again, this will be fast.
  
  This affects the speed of the two functions
  alloc_field_info() that should be slightly faster now
  free_field_info() that was replaced with a 2 line macro.
  
  All in all  my testing suggests that ethereal is 2-3% faster with this patch.
