[PATCH] Add missing global iterators for DomainLayout

[Richard Guenther]

The following patch allows one to iterate over all global patches
(for serial IO) even if only using a DomainLayout.

Tested on serial powerpc-unknown-linux-gnu with (obviously) no
regressions.

        * Layout/DomainLayout.h: added beginGlobal(), endGlobal()
        iterators, sizeGlobal() as in LayoutBase
