Update to version 0.9.9.1.

Changes from 0.9.8 to 0.9.9.1
=============================

* Updated protocol version to 1.2.

  Clients and servers with support for 1.1 are not compatible with
  the new protocol!

* Print notify for server opers when backup router comes online.
* Resolve the client's public key in JOIN command if the founder auth
  data is being requested but we don't know the client's public key.
* Added idle and signon fields to the ATTRIBUTE_SERVICE attribute to
  indicate the user's current idle and signon timeof a service.
* Added MAC field to the Private Message Payload to protect against
  chosen ciphertext attacks.
* Defined the SILC_MESSAGE_FLAG_SIGNED.
* Added ERR_UNSUPPORTED_PUBLIC_KEY and ERR_OPERATION_ALLOWED status
  types.
* Added support for normal client to kill its own entries from
  the network.
* Compute maximum padding for authentication packets to make
  passphrase approximation attacks impossible (padding must be at
  least 8 bytes now).
* Added support for rekey before 2^32 sequence number wraps.
* Added Encrypt-Then-MAC order to SILC packet MAC generation.
  Deprecated the old Encrypt-And-MAC order.
* Added Encrypt-Then-MAC order to Channel Message Payload MAC
  generation.
* Added support for setting FOUNDER mode on channel with specific
  public key which can be set with CMODE command.
* Don't wait for EOF after socket error has occurred, but close the
  connection.
* Assure the RESUME_CLIENT packet is not sent to twice to backup
  router if the detached client was originated from the backup.
* Added support for removing client from invite list when kicked
  from channel, as SILC 1.2 dictates.
* Added support for the SILC 1.2 BAN and INVITEcommands and new
  ban and invite lists to server.
* Remove client from invite list in KILLED notify and in KILL
  command.
* Do not send invite list back unless asked (when sending no
  arguments) or when list was modified.
* MARS is now gone.
* Added manual pages for silcd(8) and silcd.conf(5).

* Fixed WATCH command reply handling on normal server which was
  missing altogether.
* Fixed double free in WHOIS query on normal server when forwarding
  query to router.
* Fixed MOTD command reply sending.
* Fixed the INVITE command to send the invite list in command reply.
* Fixed PING command sending in client library and handling in
  server.  The server ID must be ID Payload, not raw ID data.
* Fixed NICK command to not crash if nickname was not sent.
* Fixed channel's global_user boolean checking after detaching.
  Check it after changing the owner of the client not before.
* Fixed channel key distribution after resuming detached client.
* Fixed memory leaks with SIMs in server.
* Fixed bugs in invite list handling in INVITE command.
