Log Message:
lint: clean up suppression of warnings and errors

Since lint1.h 1.11 from 2001-12-13, lint1 had been a memory hog.  While
it used a bit set for keeping track of the message IDs of the suppressed
messages, it only used the lower 4 bits of each 32-bit word, due to a
missing CHAR_BIT in __NERRBITS.

As a quick hack, the bit set had 1024 entries, much more than the number
of actual messages, which is currently at 350.  This meant 674 bytes of
wasted memory, plus the code size for the bit manipulations.

The only functional change is that the option '-X' now only accepts
actually valid message IDs.  Previously it had accepted all numbers from
0 to 1023.
