Tls-crypt v2 is more complicated to implement a proper stateless
handshake. To allow state handshake this commit does
- introduce a new packet CONTROL_WKC_V1 that repeats the wrapped
client key.
- introduce a way to negotiate the support for this packet in the
three way handshake
Details about the protocol changes are in tls-crypt-v2.txt. Optional
arguments to the tls-crypt-v2 option have been added to explicitly
allow or disallow client that do not support the stateless handshake.

Patch v4: remove explicit flag for ability to resend WKc,

OpenVPN Plugins
---------------
Starting with OpenVPN 2.0-beta17, compiled plugin modules are
supported on any *nix OS which includes libdl or on Windows.
One or more modules may be loaded into OpenVPN using
the --plugin directive, and each plugin module is capable of
intercepting any of the script callbacks which OpenVPN supports:
(1) up
(2) down
(3) route-up
(4) ipchange
(5) tls-verify
(6) auth-user-pass-verify
(7) client-connect
(8) client-disconnect
(9) learn-address
See the openvpn-plugin.h file in the top-level directory of the
OpenVPN source distribution for more detailed information
on the plugin interface.
Included Plugins
----------------
auth-pam -- Authenticate using PAM and a split privilege
execution model which functions even if
root privileges or the execution environment
have been altered with --user/--group/--chroot.
Tested on Linux only.
down-root -- Enable the running of down scripts with root privileges
even if --user/--group/--chroot have been used
to drop root privileges or change the execution
environment. Not applicable on Windows.
examples -- A simple example that demonstrates a portable
plugin, i.e. one which can be built for *nix
or Windows from the same source.
Building Plugins
----------------
cd to the top-level directory of a plugin, and use the
"make" command to build it. The examples plugin is
built using a build script, not a makefile.
