config: comment, minor upgrade, quote and layout configure.ac

Group statements per section as per Autoconf standard layout
Quote statements where appropriate.
Autoconf recommends not using dnl instead of # for comments

Use AC_CONFIG_FILES to replace the deprecated AC_OUTPUT with parameters.
Use AC_PROG_LIBTOOL to replace the deprecated AM_PROG_LIBTOOL
Add AC_CONFIG_SRCDIR([Makefile.am]) where missing
No functional configuration changes

This helps automated maintenance and release activities.
