Simple toolbox-style menu system. Brecht will review it
though, and/or check on way to use it for menus.
I tried to avoid uiBlock and rna stuff all over. :)

Examples you can read in:
- editors/screen/screen_ops.c:testing123() (press F5)
- editors/object/object_edit.c:object_add_primitive_invoke()
(press SHIFT+A)

Concept is simple:

uiMenuBegin(): returns a handle.
uiMenuEnd(): puts it all to work.

In between you can add items like:

uiMenuItemVal(): a name, icon, retval (use uiMenuFunc())
uiMenuItemO(): an operator + icon
uiMenuItemEnumO(): an operator, property name, value

Sublevels go easy too:

uiMenuLevel(): creates item for sublevel, with function pointer.
Inside that function you can use all menu calls again.
Levels can go as deep you want.

uiMenuLevelEnumO(): creates operator sublevel for an enum
