Vadim Zeitlin 3ffa651a34 Move wxAdv library contents into wxCore 
This basically removes the "adv" library, even though it's still
preserved for compatibility with user make/project files referring to
it.

It is done because the distinction between "adv" and "core" was never
really clear (e.g. why wxTreeCtrl was in core but wxTreeListCtrl in
adv?) and it prevented some core classes from using adv ones.

see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43601. Because of this
we rely on binutils auto export/import support which seems to work
quite well for 4.5+. However the problem was fixed in 4.7 and later and
not exporting everything creates smaller DLLs (~8% size difference), so
do use the explicit attributes again for the newer versions.

We support building wxWidgets as a set of several libraries but we don't
support arbitrary combinations of libs/DLLs: either we build all of them as
DLLs (in which case WXMAKINGDLL is defined) or none (it isn't).
However we have a problem because we need separate WXDLLIMPEXP versions for
different libraries as, for example, wxString class should be dllexported
when compiled in wxBase and dllimported otherwise, so we do define separate
WXMAKING/USINGDLL_XYZ constants for each component XYZ.
