Added unicode support for the configuration entries on Windows

windows.c:

Windows's registry (which is technically a filesystem) uses UTF-16
for its "keys". This forces us to convert each of our UTF-8 (GLib, GTK)
configuration entries if we want to store special characters. To do that
we use the RegQueryValueExW() and do some conversation around
the function call itself.

The opposite happens when we require a UTF-16 value to be read from the
registry and converted to UTF-8 in subsurface_set_conf().

An addition to this patch is a somehow expandable buffer in
windows.c: subsurface_get_conf(). We increase the size of the buffer
in chunks of 64 bytes, until RegQueryValueExW() is able to write to it
(as suggested by the WINAPI documentation).
