Document the inlining of files in openvpn and document key-direction

This patch documents the usage of inline files in OpenVPN. Hackish ways of
inline files are deliberately left out. For tls-auth and
secret the key-direction option is right way of specifying the direction
and not by using two tls-auth/secret lines where the first sets the
direction and has a dummy file name and the second sets the inline file
data but does not reset the direction parameter.

Also pkcs12 [[INLINE]] base64encoded_data works but is a quirk of how the
config parser works

Reduce --version string detail about IPv6 to just "[IPv6]".

For 2.3 release, we do not need to have more details, as there is no
separate patch set anymore, and both IPv6 transport and IPv6 payload
(PF_INET6) have been fully integrated.

Put actual OpenVPN command line on top of corresponding log file.

This is useful if a test fails, and the tester wants to run the very
same OpenVPN call with the very same arguments interactively to
pinpoint and fix the problem.

Keep pre-existing tun/tap devices around on *BSD

This amends commit 62c613d46dc49 to check whether a named tun/tap
device ("--dev tunX" instead of "--dev tun") exists before OpenVPN
started - if yes, keep around at program end.  If no, destroy.

Also has a spelling fix, and changes clear_tuntap() to be "static"
(only ever called from within tun.c).

Tested on FreeBSD 7.4, FreeBSD 9.0, NetBSD 5.1, OpenBSD 4.9

Merge getaddr_multi and getaddr6 into one function

the getaddr6 and getaddr_mutli functions are duplicates of each other.
Since we always require getaddrinfo to be present both function are merge
into one openvpn_getaddrinfo.

This functions also returns a standard struct addrinfo* so our resolve
interface is closer to the standard unix interface. The getaddr function
is a wrapper which provides backward compatibility for IPv4 addresses.
Ipv6 calls and calls to getaddr_multi are replaced with the new interface.
