	* version.h.in: (pid_output*) add const qualifier.
	* command.h: Change DEFUN func to take const char *[] rather
          than char **, to begin process of fixing compile warnings in lib/.
          Nearly all other changes in this commit follow from this change.
        * buffer.{c,h}: (buffer_write) pointer-arithmetic is gccism, take
          const void * and cast an automatic const char *p to it.

        * command.c: (zencrypt) const qualifier
          (cmd_execute_command_real) ditto

          Fix leak of getcwd() returned string.
        * memory.{c,h}: Add MTYPE_DISTRIBUTE_IFNAME for struct dist ifname.
        * distribute.{c,h}: Update with const qualifier.
          (distribute_free) use MTYPE_DISTRIBUTE_IFNAME
          (distribute_lookup) Cast to char *, note that it's ok.
          (distribute_hash_alloc) use MTYPE_DISTRIBUTE_IFNAME.
          (distribute_get)  Cast to char *, note that it's ok.
