Revert workarounds for -Wmissing-braces false positives on old GCC

Browse Source 
We have collected several instances of a workaround for GCC bug 53119,
which caused false-positive compiler warnings.  This bug has long been
fixed, but was still seen on the buildfarm, most recently on lapwing
with gcc (Debian 4.7.2-5).  (The GCC bug tracker mentions that a fix
was backported to 4.7.4 and 4.8.3.)

That compiler no longer runs warning-free since commit 6fdd5d9563, so
we don't need to keep these workarounds.  And furthermore, the
consensus appears to be that we don't want to keep supporting that era
of platform anymore at all.

This reverts the following commits:

d937904cce
506428d091
b449afb582
6392f2a096
bad0763a4d
5e0c761d0a

and makes a few similar fixes to newer code.
