Log Message:
An important note to all server users:

The private key file format has changed due to a bug in the
older code.  When you run this server version it automatically
changes your private key file to the correct format.
The future versions of the SILC Server will not do that, so
do not skip this version or you will need to generate new key
pair after 0.9.11 is released.

Also backup router bugs was fixed which caused several
interesting decryption problems, so upgrading regardless
if you are runinng normal server, backup router or primary
router is strongly recommended.

Changes from 0.9.9.1 to 0.9.10
==============================

* Added the config directive PublicKeyDir for the client
  block.
* Extended the SILC_SERVER_LOG_ERROR macro to all available
  logging channels.
* Load only files with .pub suffix in PublicKeyDir.

* Fixed a typo in resuming code that fixed detach/resume
  code in server.
* Fixed CMODE setting in server when founder mode was set.
* Fixed wrong invite and ban list handling in server command
  reply.
* Fixed CUMODE founder authentication in server to not check
  for client's public key since it's not supposed to do that.
* Fixed backup router bugs: When backup resumes router and
  receives a CHANNEL_MESSAGE packet the backup must not act
  as router since the packet header decryption would be
  different.  Also, when relaying packets to channel, do not
  re-encrypt packets on backup that came from the primary
  since the connection isn't really router-router connection.
