Extend parser to accept binary constants that begin with '0b' or '0B'.
* NEWS: Announce change:
* lex.ll: Define NUMBIN to be 0[bB] followed by 0,1, or '_'.
Define NUMBER to be NUMREAL|NUMHEX|NUMBIN.
*lex.ll (looks_like_bin): New function to detect 0[bB] prefix.
*lex.ll (handle_numbe): Call looks_like_bin() and if found then convert
binary string to double.
* parser.tst: Add tests for new behavior.
