PATCH COMMITTED: fix libdecnumber builds w/o stdint.h

[Ben Elliston]

When I upgraded libdecnumber to version 3.61 on Monday, I lost a local
patch that allows building on non-C99 systems without <stdint.h>.  This
change reintroduces that patch and I am committing it now.

Sorry to those affected by the breakage.

        * decContext.h: Include gstdint.h instead of <stdint.h>.
