Clean up handling of missing functions.
With autotools, CMake, and nmake, if we have a function, #define
HAVE_{function_name_in_all_caps}, otherwise don't #define it.
If we provide our own version of a function in libwsutil, make sure we
have a header that declares it, and *ONLY* include that header if
HAVE_{function_name_in_all_caps} is *NOT* defined, so that we don't have
the system declaration and our declaration colliding.
Check for inet_aton, strncasecmp, and strptime with CMake, just as we do
with autotools.
Simplify the addition of {function_name_in_all_caps}_LO to libwsutil in
autotools.
