Security update to version 1.0.3

- Further robustification against corrupted compressed data.
  There are currently no known bitstreams which can cause the
  decompressor to crash, loop or access memory which does not
  belong to it.  If you are using bzip2 or the library to
  decompress bitstreams from untrusted sources, an upgrade
  to 1.0.3 is recommended.
