These aren't needed in C89 and later, but can hide missing prototypes
that generate broken code on platforms where pointers are larger than ints.

evi_return is passed in as a pointer to a location into which
XeviGetVisualInfo is expected to write a pointer to the memory
it allocated for the returned structures. If we're failing and
bailing out, we need to dispose of the pointer we set, not the
one passed into us (which the caller may have put on the stack
or allocated as part of a larger structure).
Flagged by cppcheck 1.64:
[lib/libXext/src/XEVI.c:182] -> [lib/libXext/src/XEVI.c:186]:
(warning) Possible null pointer dereference: evi_return - otherwise it
is redundant to check it against null.

_XEatDataWords was orignally introduced with the May 2013 security
patches, and in order to ease the process of delivering those,
fallback versions of _XEatDataWords were included in the X extension
library patches so they could be applied to older versions that didn't
have libX11 1.6 yet. Now that we're past that hurdle, we can drop
the fallbacks and just require libX11 1.6 for building new versions
of the extension libraries.

If the number of visuals or conflicts reported by the server is large
enough that it overflows when multiplied by the size of the appropriate
struct, then memory corruption can occur when more bytes are read from
the X server than the size of the buffer we allocated to hold them.

rep.length is a CARD32, so rep.length << 2 could overflow in 32-bit builds
