sem_init() is not functional on Mac OS. Use the Grand Central Dispatch
implementation.
Make libscp_lock.c use semaphores through the thread_calls wrapper.
In RHEL and its clones, /usr/bin/Xorg is set suid-root. To execute
Xorg with user privileges, /etc/pam.d/xserver needs be edited [1],
or suid bit of Xorg binary needs to be dropped.
In order to keep Xorg and /etc/pam.d/xserver untouched, preparing
non-suid version of Xorg as /usr/bin/Xorg.non-suid for example is
the simplest solution. However, Xorg.non-suid cannot be executed
since it is hardcoded to execute Xorg in sesman.
This change makes more flexible to execute Xorg with non-standard
name or not in PATH environment variable.

Add Autoconf archive macros to check for -Wall and its dependencies.
Adjust m4/.gitignore to only ignore libtool macros.
Require Autoconf 2.65 for compatibility with Autoconf archive macros.
Use install-data-hook to ensure restrictive permissions on rsakeys.ini.
Don't create rsakeys.ini in init scripts. This makes xrdp functional upon
"make install" without relying on the init scripts.
Packagers should not package rsakeys.ini, it should be created when the
package is installed.
in case getaddrinfo(3) might fail.
In FreeBSD, AI_V4MAPPED support for getaddrinfo(3) was very recently
implemented[1]. Most of FreeBSD systems in the world do not have
this implementation yet. This will be a problem when AI_V4MAPPED
isn't supported and xrdp is built with IPv6 option. In such a case,
g_tcp_connect always fails.
Of course getaddrinfo(3) might fail in other cases. The log helps
us to know what's happening.
