[PATCH app-xlsclients] configure.ac: regroup statements and comment

[Gaetan Nadon]

Add missing AC_CONFIG_SRCDIR([Makefile.am])

Move AC_USE_SYSTEM_EXTENSIONS higher up in Autoconf init section
which must come before XORG_DEFAULT_OPTIONS

Move XORG_DEFAULT_OPTIONS to its usual place with X.Org macros
Note that AC_FUNC_STRNLEN calls AC_REQUIRE(AC_USE_SYSTEM_EXTENSIONS)

Comment the strnlen function replacement.

No functional changes. Following the layout in
http://www.x.org/wiki/NewModuleGuidelines
