Establish 'break scope' within fz_try macro
It is vital that no one returns from within fz_try. As such it's often
necessary to jump out of an fz_try. This can mean using a label at the
end of the fz_try section to goto.
By introducing a "do { } while (0)" around the contents of the fz_try
we allow people to 'break' (or 'continue') to get out neatly.
