Fix AddressSanitizer (./configure --enable-asan) builds

"./configure --enable-asan" currently fails to detect installed libraries
because aclocal-fallback/* built programs have memory leaks in them.

This system is running 64-bit Ubuntu Linux 15.10 with GCC 5.2.1
compiler.

The glib-2-0.m4 leak, and the gtk-3.0.m4 leak are fixed by updating
"glib-2.0.m4" to the latest upstream version.

Whitespace errors are fixed locally to keep the BuildBot happy.
