GtkApplicationX11: read the startup ID from the platform data

If the platform data passed with actions and activations includes
a startup notify ID, we should read it and pass it down to GDK.
This ensures that the right startup notify is completed after the
signal emission, and that the user time of the GdkDisplay is properly
updated (which in turn makes sure the windows are not subjected
to focus-stealing-prevention)

window: Document GtkWindow::set-focus

Not sure why this was never documented.
configure: use CFLAGS, etc. _FOR_BUILD as well

When not doing cross-builds, use the values of CFLAGS, CPPFLAGS and
LDFLAGS as the default value for CFLAGS_FOR_BUILD, CPPFLAGS_FOR_BUILD
and LDFLAGS_FOR_BUILD, respectively.

This avoids having to manually specify these variables in order to get
extract-strings to build properly.

This should really be handled by ax_prog_cc_for_build.m4.  That has been
reported upstream.  This is a workaround for now.
