Run pgindent with new pg_bsd_indent version 2.1.1.

Thomas Munro fixed a longstanding annoyance in pg_bsd_indent, that
it would misformat lines containing IsA() macros on the assumption
that the IsA() call should be treated like a cast.  This improves
some other cases involving field/variable names that match typedefs,
too.  The only places that get worse are a couple of uses of the
OpenSSL macro STACK_OF(); we'll gladly take that trade-off.
