Log Message:
zkt: update to 1.1.6.

zkt 1.1.6 -- 04. Jan 2023

* misc	New configure.ac file generated by 'autoscan'

* bug	Jan Münnich found out that "-fcommon" is needed to compile ZKT
	with gcc 10.
	This is because of a double external definition caused by
	including header files while defining "extern" as empty.
	This is fixed now by eliminating includes within include files
	so "-fcommon" is not needed.

* misc	Increase of some string vars because of compiler warnings

* bug	Fixed an empty statement (semicolon) in freeconfig()
	(Thank you gcc!)

zkt 1.1.5 -- 17. Jun 2019

* misc	Option -r of dnssec-keygen has been deprecated since 9.13 (or so)
	Usage removed in dki_new()

* func	recursive_file_mtime() function added by Sven Stickroth
	This is useful if several zone files are included in a main zone.db
	file to track a change of any of the input files.
	It is not compiled in by default (use configure --enable-inc-file-tracking
	to enable) because for large zone files this could be a time consuming process.
	It is possible to add all included files to the local config parameter
	"DependFiles" instead. (Use zkt-conf <zonefile> to get a list \ 
of files to be added).

* misc	Log name of zone if KSK is expired
	Thanks to Sven Stickroth

* misc	DEST_DIR added to Makefile to install executables at common places
	Thanks to Sven Stickroth

* bug	Fix typos in rollover.c
	make clean also cleans OBJ_KLS files
	Thanks to Sven Stickroth
