This tests an illegal client that sends an info line and closes 'immediatly'.

Since no test suites includede test_server.hrl, there is no need
to have test_server in the include path or code path.

This patch allows extra callback options to be passed to the module
implementing the SSH callback module behaviour.

A module implementing the SSH key callback API is used to customize
the handling of public key. This patch allows extra callback options
to be passed to the module implementing the SSH callback module
behaviour.

The key_cb option has been changed:

  {key_cb, atom()} -> {key_cb, key_cb()}

  Where:
	key_cb() :: atom() | {atom(), list()}

The callback options, if specified, is made available to the callback
module via the options passed to it under the key 'key_cb_private'.

More details and some backgorund is available here[1].

Add ssh_trpt_test_lib:instantiate/2, ssh_test_lib:default_algoritms/2 and algo_intersection/2
ssh_to_openssh_SUITE uses only algos that sshd and ssh client supports
raised timeout limit in ssh_basic_SUITE:ssh_connect_arg4_timeout
Break out ssh_renegotiate_SUITE from ssh_basic_SUITE
Move std_daemon/4 to ssh_test_lib.erl
Add ssh_algorithms_SUITE
Add ssh_options_SUITE
Add assymetric testing of algorithms
Add openssh tests to ssh_algorithms_SUITE
Remove algo tests from ssh_sftp_SUITE (now in ssh_algorithms_SUITE)
Removed kex algo tests from in ssh_basic_SUITE because they are now in ssh_algorithm_SUITE.
fixed test case ssh_protocol_SUITE:no_common_alg_server_disconnects/1

This test lib is intended for deeper testing of the SSH application. It
makes it possible to do exact steps in the message exchange to test "corner
cases"

This suite tests that upgrade/downgrade works from/to both minor and major versions.  It is modelled after the ssl_upgrade_SUITE.

A precondition for success is that the ssh.appup file is correct.
