Scrub remaining BOS reference from Multics

[canthony]

(See ticket #116)

BOS functionality has been removed from Multics, but there are still traces of it in the source.

When setting up the default cold boot RPV partition, a BOS partition is included:

          call part_side_door ("bos", "high", DEFAULT_RPV_BOS_SIZE_char);
          call part_side_door ("dump", "high", DEFAULT_RPV_DUMP_SIZE_char);
          call part_side_door ("log", "high", DEFAULT_RPV_LOG_SIZE_char);
          call part_side_door ("file", "high", DEFAULT_RPV_FILE_SIZE_char);
          call part_side_door ("bce", "high", ltrim (char (BCE_PART_LTH)));

          declare 1 found                aligned,
                    2 hc                 bit (1) unaligned,
                    2 conf               bit (1) unaligned,
                    2 bos                bit (1) aligned,
                    2 bce                bit (1) aligned,
                    2 file               bit (1) aligned;

               else if label.parts (j).part = "bos"
               then found.bos = "1"b;

(That code has already been fixed to not require a BOS partition: found.bos is set but not used.)

          do part = "bos", "conf", "log";

          do part = "bos", "conf", "log", "dump";

     proper_name (3)          char(8) init    /* proper name equivalent               */
          ( "hardcore", "bos", "mcs" );

               then go to got_odd_lib;                                /*  .  */
                                                                      /*  .  */
          call MATCH_PATHS (dn, ">ldd>bos>execution", code );         /* BOS */
          if code = 0
               then go to got_odd_lib;

Several mentions of "bos" but I believe not referring to the BOS partition.

ldd>>tools>source>bound_azm_.s.archive
ldd>include>amu_mc.incl.pl

Several mentions of "bos" in comments, probably not relevant.

documentation>subsystem>bce>bos.info

Should be deleted.

documentation>info_segments>multics_libraries_.info

'bos' is included in a list of libraries as part of bootload; the reference should be deleted.

coldboot requires a bos partition:
