* 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.
(buffer_putstr) add const
* command.c: (zencrypt) const qualifier
(cmd_execute_command_real) ditto
(cmd_execute_command_strict) ditto
(config_log_file) 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.
* filter.c: Update with const qualifier.
* if.{c,h}: ditto.
* if_rmap.{c,h}: ditto.
(if_rmap_lookup) Cast to char *, note that it's ok.
(if_rmap_get) ditto.
* log.{c,h}: Update with const qualifier.
* plist.{c,h}: ditto.
* routemap.{c,h}: ditto.
* smux.{c,h}: ditto. Fix some signed/unsigned comparisons.
* sockopt.c: (getsockopt_cmsg_data) add return for error case.
* vty.c: Update with const qualifier.
