        syssrc/usr.sbin/config: defs.h files.c gram.y hash.c main.c mkheaders.c
            mkioconf.c mkmakefile.c mkswap.c pack.c scan.l sem.c sem.h util.c

Log Message:
Functionality improvements:
- Add `no' keyword, which can be used in the following ways:
        no file-system SOMEFS
        no makeoptions FOO
        no options OPT1[,OPT2[,...]]
        no pseudo-device somepseudo
  This turns off a previous file-system/makeoptions/options/pseudo-device
  entry for the same item.
  Grammar support for 'no device DEV at ATTACH' added, but not
  implemented yet.

Code changes:
- Convert many simple lists to TAILQs
- Convert prefix to SLIST
- Remove argument names from prototypes.
- Don't bother with custom alloc code for hashtables; just use emalloc()
  like everything else.
- Implement ht_remove(), to remove an entry from a hash table.
  Add removed entries to a freelist for later reuse.
- Don't selectbase() devices and pseudo-devices at definition time; instead
  do it at one pass after the config file has been parsed in fixdevis().
- Rename nvhead to nvfreelist; a more apt name...
- Minor code cleanups.
