Second round of warning suppression.

Used a #pragma to kill ~170 in rpcgen code.  Added GF_UNUSED to deal with
a few more from macros elsewhere.  The remainder are function return values
(mostly context and dict calls) that really should be checked.  Those would
be harder to fix without real understanding of the code where they occur,
so they remain as reminders.

(Patchset 2: deal with older gcc that doesn't handle #pragma GCC diagnostic)

(Patchset 3: fix include paths in generated files)

(Patchset 4: keep up with trunk, squash 9 new warnings)

(Patchset 5: six more, all in AFR)
