In `Fopen` function variable `iop` may store NULL as a result of `fopen`
call. In this case, if later privileges couldn't be restored (`seteuid`
call fails), further `fclose(iop)` call will cause runtime error.
This commit adds check `iop` for NULL before calling `fclose` to prevent
potential NULL pointer dereference.

Most of these flags aren't used by any drivers, so no need to keep them

The OS abstraction isn't really the right place for those flags,
they are're probably better off in their corresponding extensions.

PANORAMIX was the original working title of the extension, before it became
official standard. Just nobody cared about fixing the symbols to the official
naming.
For backwards compatibility with drivers, the old PANORAMIX symbol will
still be set.

Support for using getaddrinfo() was originally added to support IPv6,
and only used if IPv6 support was enabled. Two decades later, support
for getaddrinfo() is ubiquitous and OS'es have marked gethostbyname()
as deprecated, so use the modern interface whenever we can now.

The symbol controls whether to include dix-config.h, and it's always set,
thus we don't need it (and dozens of ifdef's) anymore.
This commit only removes them from our own source files, where we can
guarantee that dix-config.h is present - leaving the (potentially exported)
headers untouched.

* this symbol is a server configuration flag (can be passed via cmdline)
for limiting the max size of big-requests. there shouldn't be any need
to use it outside the core X server (in server modules like drivers
or external extension) - therefore unexport it
* in order to reduce namespace pollution of public (server module API)
headers, create a new internal header for those tings (more to come)
