Don't assume AF_INET family. Don't assume the socket is connected. Report
local address and port. Don't try to close non-sockets and invalid file
descriptors. Report errors getting socket information and closing the
socket. Use more appropriate log levels.
broken by #314. This is compatible with the fix introduced in #314.
To use non-ASCII text/filename in clipboard, chansrv needs to be run
with LC_CTYPE=*.UTF-8 because the behaviour of mbstowcs(3) function
called in chansrv depends on LC_CTYPE[1]. However #314 made
LC_CTYPE=C in chansrv context. Even if LANG and LC_* are set in
.bashrc, /etc/profile, /etc/locale.conf or something like that,
it doesn't affect in chansrv context because chansrv doesn't source
any of them unlike sesman.
So do not set LC_CTYPE to blank or "C" in g_init() in order to get
g_mbstowcs and g_wcstombs to work properly with non-ASCII UTF-8
characters in any context.
Setting LC_CTYPE to *.UTF-8 doesn't obstruct applying system
language in RHEL [2].
[1] Linux man page says:
The behavior of mbstowcs() depends on the LC_CTYPE category of
the current locale.

This fixes loading modules compiled with a C++ compiler. Remote thandle
type, it's unused. Use tintptr for module data. Don't cast pointers to
long, they won't fit on Win64.
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 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.
