Merge branch 'peppe/common_test/telnet_logging_system'

* peppe/common_test/telnet_logging_system:
  Add verification terms for the unix_telnet test case
  Add documentation about logging in the ct_telnet module
  Make temporary fix of problem that sometimes causes the ct_util server to die
  Fix remaining problems using raw telnet logging for parallel test cases
  Make it possible to use raw telnet logs in parallel test case groups
  Implement tests for logging traffic for multiple telnet connections
  Add and improve test cases
  Implement new telnet logging system

+%%
+%% == Logging ==
+%%
+%% `ct_telnet' can be configured to uses the `error_logger' for logging telnet
+%% traffic. A special purpose error handler is implemented in
+%% `ct_conn_log_h'. To use this error handler, add the `cth_conn_log'
+%% hook in your test suite, e.g:
+%%
+%%
+%% ```
+%% suite() ->
+%%    [{ct_hooks, [{cth_conn_log, [{conn_mod(),hook_options()}]}]}].
+%%'''
+%%
+%% `conn_mod()' is the name of the common_test module implementing
+%% the connection protocol, i.e. `ct_telnet'.
+%%
+%% The hook option `log_type' specifies the type of logging:
+%%
+%% <dl>
+%%   <dt>`raw'</dt>
+%%   <dd>The sent and received telnet data is logged to a separate
+%%   text file as is, without any formatting. A link to the file is
+%%   added to the test case HTML log.</dd>
+%%
+%%   <dt>`html (default)'</dt>
+%%   <dd>The sent and received telnet traffic is pretty printed
+%%   directly in the test case HTML log.</dd>
+%%
+%%   <dt>`silent'</dt>
+%%   <dd>Telnet traffic is not logged.</dd>
+%% </dl>
+%%
+%% By default, all telnet traffic is logged in one single log
+%% file. However, it is possible to have different connections logged
+%% in separate files. To do this, use the hook option `hosts' and
+%% list the names of the servers/connections that will be used in the
+%% suite. Note that the connections must be named for this to work
+%% (see the `open' function below).
+%%
+%% The `hosts' option has no effect if `log_type' is set to `html' or
+%% `silent'.
+%%
+%% The hook options can also be specified in a configuration file with
+%% the configuration variable `ct_conn_log':
+%%
+%% ```
+%% {ct_conn_log,[{conn_mod(),hook_options()}]}.
+%% '''
+%%
+%% For example:
+%%
+%% ```
+%% {ct_conn_log,[{ct_telnet,[{log_type,raw},
+%%                           {hosts,[key_or_name()]}]}]}
+%% '''
+%%
+%% <b>Note</b> that hook options specified in a configuration file
+%% will overwrite any hardcoded hook options in the test suite.
+%%
+%% === Logging example 1 ===
+%%
+%% The following `ct_hooks' statement will cause raw printing of
+%% telnet traffic to separate logs for the connections named
+%% `server1' and `server2'. Any other connections will be logged
+%% to default telnet log.
+%%
+%% ```
+%% suite() ->
+%%    [{ct_hooks, [{cth_conn_log, [{ct_telnet,[{log_type,raw}},
+%%                                             {hosts,[server1,server2]}]}
+%%                                ]}]}].
+%%'''
+%%
+%% === Logging example 2 ===
+%%
+%% The following configuration file will cause raw logging of all
+%% telnet traffic into one single text file.
+%%
+%% ```
+%% {ct_conn_log,[{ct_telnet,[{log_type,raw}]}]}.
+%% '''
+%%
+%% The `ct_hooks' statement must look like this:
+%%
+%% ```
+%% suite() ->
+%%    [{ct_hooks, [{cth_conn_log, []}]}].
+%% '''
+%%
+%% The same `ct_hooks' statement without the configuration file would
+%% cause HTML logging of all telnet connections into the test case
+%% HTML log.
+%%
+%% <b>Note</b> that if the `cth_conn_log' hook is not added, telnet
+%% traffic is still logged in the test case HTML log file (on the legacy
