Update CentOS base to 6.5, add userland ports

The Fedora 10 infrastructure ports have been in use since June 2009 and, while
having served a great deed, have become unsupported upstream and hence affected
by unfixed security vulnerabilities. In addition to that, many recent Linux
binaries need newer libc / stdlibc++ versions.

This commit adds the linux-c6- userland as drop-in replacement for the -f10
infrastructure, as well as upgrading the linux_base-c6 port to CentOS 6.5.

If you want to switch to linux-c6 ports, please define at /etc/make.conf:

    OVERRIDE_LINUX_BASE_PORT=c6
    OVERRIDE_LINUX_NONBASE_PORTS=c6

Additionally, please add the following line to /etc/sysctl.conf:

    compat.linux.osrelease=2.6.18

Upgrading procedures are shown in /usr/ports/UPDATING.

This work has been inspired by Artyom Mirgorodskiy's post to emulation@ in
November 2013, using and extending mav@'s work. It has been tested extensively
and most reported issues were already fixed. Please report any additional bug
or "features" to the emulation mailing list.

Many thanks to: mav@, rene@, allanjude@, netchild@, antoine@, everyone who's

+libasyncns is a C library for Linux/Unix for executing name service queries
+asynchronously. It is an asynchronous wrapper around getaddrinfo(3),
+getnameinfo(3), res_query(3) and res_search(3) from libc and libresolv.
+
+In contrast to GNU's asynchronous name resolving API getaddrinfo_a(),
+libasyncns does not make use of UNIX signals for reporting completion of name
+queries. Instead, the API exports a standard UNIX file descriptor which may be
+integerated cleanly into custom main loops.
+
+In contrast to asynchronous DNS resolving libraries like libdenise, skadns,
+adns, libasyncns is just an asynchronous wrapper around the libc's synchronous
+getaddrinfo() API, which has the advantage of allowing name resolution using
+techniques like Multicast DNS, LDAP or NIS using standard libc NSS (Name
+Service Switch) modules. libasyncns is compatible with IPv6 if the underlying
+libc is.
+
+libasyncns is very tiny, consisting of just one header and one source file. It
+has no dependencies besides libc.
