Add experimental cmake-based build system for Windows.

include/apr.hwc is almost exactly the same as apr.hw; it uses
variables for cmake-time feature selection so that cmake
can easily generate apr.h.

+PROJECT(APR C)

+# Todos to properly support Windows:
+# . Fix problem where srcdir/include/apr.h (if it exists) is found before builddir/apr.h
+#   (and similar for apu_want.h)
+# . Document example 32-bit and 64-bit Windows builds using NMake
+# . Build and optionally run gen_test_char
+# . Build apr_app.c into libapr-2 properly (what about apr-2.lib?)
+# . Options for remaining features, along with finding any necessary libraries
