Changes:
   * cleanup: #ifdefed dump_a_txt() properly so it will not be compiled
     if --disable-master-dump was specified.
   * implement "base template" ($=) feature.
   * portability and readability fixes from Victor Duchovni
   * added configure test for inline and __inline keywords, and only
     use #warning keyword if __GNUC__ is defined (more portability fixes
     from Victor Duchovni)
   * misc type conversions here and there, and change alignment in
     mempool.c to be sizeof(void*) instead of sizeof(int), to help
     64bit platforms.  Thanks to Mike Quintero for an excellent
     bugreport.
   * bugfix: combined dataset - improper return of query() routine in some
     cases
   * internal code reorg:
     - move firstword[_lc]() to _util.c
     - use two structs instead of a set of 2-element arrays in dnset
   * bugfix: lowercase base zone names given on command line and in `combined'
     dataset, or else they wont be recognized in queries
