We need to define __WXGTK218__ symbol in configure instead of simply checking
if we are compiled with 2.18 in wx/infobar.h because GTK_CHECK_VERSION() can't
be used when compiling user code which can't even include gtk/gtkversion.h
defining it because it doesn't necessarily use `pkg-config --cflags gtk+-2.0`
at all in its CFLAGS.

Assume that user-added buttons can be already used to close the message so
don't show the default close button if any were added.

Also change the GTK implementation to use a separate wxInfoBarGTKImpl to store
its data, this object won't be even allocated if a generic implementation is
used under GTK.

Straightforward implementation of wxInfoBar using GtkInfoBar widget available
in GTK+ 2.18.
Some side effects of this change:
- Rename wxInfoBar version in wx/generic/infobar.h to wxInfoBarGeneric and
define wxInfoBar in wx/infobar.h.
- Also change default value of flags argument to ShowMessage() to
wxICON_INFORMATION from wxICON_NONE as the default colour for wxICON_NONE
messages is surprisingly ugly in GTK native version.
