build system update

* configure.ac: require autoconf 2.70 and drop check for lex-library with noyywrap option for AC_PROG_LEX
* HACKING: document dependencies autoconf 2.70 and automake 1.16 and several smaller text updates
* Makefile.am (checkmanual-code-coverage, checkall-code-coverage): new targets removing the need to do that manually
* build_aux/ltmain.sh, m4/libtool.m4, m4/ltoptions.m4, m4/ltversion.m4

cobc:
