  r299710:
  
  Staticize global variables only used in bsnmpimport.c to fix
  -Wmissing-variable-declarations warnings
  
  r299711:
  
  Fold two malloc + memset(.., 0, ..) calls into equivalent calloc calls
  
  r299763:
  
  Mute -Wstrlcpy-strlcat-size warning by using nitems with the size of the buffer
  
  This is a no-op as the malloc above set the size of the buffer to the size used
  below, but this keeps things consistent in case the malloc call changes somehow.
  
  r299783:
  
  Convert tok from enum tok to int32_t in function calls
  
  get_token(..) returns int32_t, not enum tok, and in many cases tests for items
  not in enum tok (e.g. '('). Make the typing consistent with get_token, which
  includes a domino effect of changing enum tok to int32_t.
  
  r299811:
  
  Use strdup instead of malloc + strlcpy
  
  Fix error messages on failure for calloc/strdup
