This patch adds height-for-width geometry management
for cell renderers while still responding to the old
gtk_cell_renderer_get_size() apis with virtual return values
(obtained by soliciting the new height-for-width cell renderer
apis).
At least where standard names are available, instead of relying
on a symlink forest in the icon theme directory. For directional
variants, we look up icons by the pair ("foo-rtl", "foo") or
("foo-ltr", "foo"). See bug 626474.
They were added as accessors for 2.22 even though querying the
background wasn't possible previously. As GTK 3.0 will change background
handling, it doesn't make sense at all to expose these getters.
For windows with alpha channel, the previous contents would otherwise
not be erased. Visible for example in the status icon code.
Thanks to Thomas Wood for noticing.
There were some vestiges of the gtk_{h,v}button_box_set_default_layout()
functionality left. These are gone now. I have also removed
the GTK_BUTTONBOX_DEFAULT value in GtkButtonBoxStyle, but the other
values have been kept at their numeric values, to avoid more serious
ABI change.
It is not safe to assume that copyright text in applications is
one liner, therefore it's better to split it from the program name.
Also, the license text should be in a paragraph of its own, so
add an extra '\n' above it.

* Makefile.decl: make sure that check-local does not depend on a
recursive target for the tests. This way check can recurse and call
check-local in each folder which then invokes test-cwd. This will
make sure that a toplevel check-local doesn't recurse into subfolders
as well. The was resulting in test being run twice (for "/tests"), tree
times (e.g. for "/gtk/tests") and potentially more often
