This basically repeats commit bad67799
after the upgrade to libX11 1.3.4.

Upstream has changed the header guards. We adapt them to prevent double inclusion.

This should have been part of commit 2c31ce2f which also happens to
have a wrong description... Sigh.

 os: Eliminate uninitialized value warnings from access.c

siAddrMatch doesn't need addr to be a useful value, it checks
some things like localuser without having an address at all.

v2: backport to nx-libs 3.6.x (Ulrich Sibiller)

The ConvertAddr function doesn't reliably set the 'addr' return value,
and so callers are getting flagged for using potentially uninitialized
values. Initialize the value in the callers to NULL and then go ahead
and check for NULL values before using them.

v2: backport to nx-libs 3.6.x (Ulrich Sibiller)

GetHosts saves the pointer to allocated memory in *data, and then
wants to bounds-check writes to that region, but was mistakenly using
a bare 'data' instead of '*data'. Also, data is declared as void **,
so we need a cast to turn it into a byte pointer so we can actually do
pointer comparisons.

Just like upstream does

just as upstream did

it is no longer needed because the code here is only used in the server.
