 * Routine to print 32 bit bitmasks
 *
 * Takes:
 *  fp  - a file descriptor
 *  fmt - optional text
 *  ul  - unsigned long bit vector
 *  bitfmt  - special string to map bits to words.
 *      bitfmt is layed out as follows:
 *          byte 0 is the output base.
 *          byte 1 a bit position less than 32
 *          byte 2-n text for position in byte 1
 *          byte n+1 another bit position
 *          byte n+2-m text for position in byte n+1
 *              .
 *              .
 *              .
 *
 *      Eg. - "\020\001DOG\002CAT\003PIG"
 *      Print the bitmask in hex.
 *      If bit 1 (0x0001) is set print "<DOG>"
 *      If bit 2 (0x0002) is set print "<CAT>"
 *      If bit 3 (0x0004) is set print "<PIG>"
 *      If bit 4 (0x0008) is set nothing is printed.
 *      If bit 1 and bit 2 (0x0003) are set print <DOG,CAT>
 *
 *  Returns 0 on OK
 *      EOF on error
 *
 *  Outputs on fp
