Subject: Incremented version to 2.1_rc7d.

Support asynchronous authentication by plugins by allowing
OPENVPN_PLUGIN_AUTH_USER_PASS_VERIFY to return
OPENVPN_PLUGIN_FUNC_DEFERRED.  See comments in
openvpn-plugin.h for documentation.  Enabled by ENABLE_DEF_AUTH.

Added a simple packet filter functionality that can be driven by
a plugin.  See comments in openvpn-plugin.h for documentation.
Enabled by ENABLE_PF.

See openvpn/plugin/defer/simple.c for examples of ENABLE_DEF_AUTH
and ENABLE_PF.

"TLS Error: local/remote TLS keys are out of sync" is no longer a
fatal error for TCP-based sessions, since the error can arise
normally in the course of deferred authentication.  In a related
change, allow packet-id sequence to begin at some number n > 0 for
TCP sessions, rather than strictly requiring sequence to begin
at 1.

Added a test to configure.ac for LoadLibrary function on Windows.

Modified "make dist" function to include all files from
install-win32 so that ./domake-win can be run from a
tarball-expanded directory.

setenv and setenv-safe directives may now omit a value argument
which defaults to "".
