Updated to 2.1.1.

Changes:

2009.12.11 -- Version 2.1.1

* Fixed some breakage in openvpn.spec (which is required to build an
  RPM distribution) where it was referencing a non-existent
  subdirectory in the tarball, causing it to fail (patch from
  David Sommerseth).

2009.12.11 -- Version 2.1.0

* Fixed a couple issues in sample plugins auth-pam.c and down-root.c.
  (1) Fail gracefully rather than segfault if calloc returns NULL.
  (2) The openvpn_plugin_abort_v1 function can potentially be called
  with handle == NULL.  Add code to detect this case, and if  so, avoid
  dereferencing pointers derived from handle  (Thanks to David
  Sommerseth for finding this bug).

* Documented "multihome" option in the man page.

2009.11.20 -- Version 2.1_rc22

* Fixed a client-side bug on Windows that occurred when the
  "dhcp-pre-release" or "dhcp-renew" options were combined with
  "route-gateway dhcp".  The release/renew would not occur
  because the Windows DHCP renew function is blocking and
  therefore must be called from another process or thread
  so as not to stall the tunnel.

* Added a hard failure when peer provides a certificate chain
  with depth > 16.  Previously, a warning was issued.
