Changes from 0.7.9 to 0.8:
==========================
* Removed 0.6.x backwards support.
* Added `prefer_ipv6' argument to the functions
silc_net_gethostbyname[_async]. If it is TRUE it will return
IPv6 address over IPv4. If FALSE IPv4 address is returned
even if IPv6 address was found.
* Added support silc_net_create_connection[_async] to fallback
to IPv4 address if IPv6 address could not be used (like if
it doesn't work on a specific system). Affected file in
* Added `user_count' to the SilcChannelEntry which now tells the
number of users on the channel. The user count is now saved
in normal server of global channels as well.
* Added following new config file settings:
channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
key_exchange_timeout, conn_auth_timeout, connections_max,
links_max.
Implemented all the new config settings handling in the server.
Optimized the use of SKE Mutual flag usage. Use it only
if connection authentication protocol is not based in public
key authentication.
* Added new configuration options and blocks:
keepalive_secs, reconnect_count, reconnect_interval,
reconnect_interval_max, reconnect_keep_trying and
require_reverser_lookup. Added ConnectionParam block, and
implemented the connection parameters when connecting as
initiator and when accepting connections as responder.
* Splitted the doc/example_silcd.conf.in. Separated the crypto
algorithm parts and created new file silcalgs.conf, that
is now included from the example_silcd.conf.in.
* Optimized the silc_server_connect_to_router_second to take
the connection configuration object from the SilcServerConnection
object instead of finding it during the connecting phase.
Added the configuration object to SilcServerConnection struct.
* Fixed the public key authentication to allocate always the
destination signature buffer instead of using static buffer.
* Added new Passphrase and Publickey authentication methods to
config file, allowing both public key and passphrase based
authentication to be set at the same time.
Added `prefer_passphrase_auth' setting in config file which
can be used to set to prefer passwd auth if both passwd and
public key is set. If not set, public key is preferred.
This has effect only when being initiator (responder will try
both anyway).
Added support for authentication with passphrase and public key
at the same time. The passphrase is tried first always since
it is faster to check.
* Merged the new SILC Config library, with the server parsing
support. Read the header file silcconfig.h or the toolkit
documentation for the news.
