Update autoconf/automake standards

Generated files config.guess config.sub depcomp install-sh ltmain.sh missing
and ylwrap have been moved to build-aux/

Ran autoupdate

Replaced AC_TRY_LINK/AC_TRY_COMPILE by AC_LINK_IFELSE/AC_COMPILE_IFELSE

Droped -I$(top_srcdir)/include from CFLAGS since AC_CONFIG_HEADERS already
adds the -I

Fixed bison detection

Added AM_PROG_AR as required by autoreconf -i -Wall

Updated NEWS and .gitignore
