* siri/ct_netconfc/log-silent/OTP-13035:
  Don't attempt logging when log type is 'silent'

The error logger handler ct_conn_log_h in common_test did not respect
the 'silent' option, and tried to print to an undefined file
descriptor. This has been corrected.

The netconf server collects data until an XML tag is completed before
pretty printing received data. Each time data is logged, a heading
like the following is printed:

= CT_NETCONFC ==== 28-Sep-2015::16:43:46,842 ===================================
= Client <0.194.0> <----- {"127.0.0.1",2060} ===================================

This commit removes printing of this header if there is no data to be
printed below - i.e. if the XML tag is not yet complete and we are
waiting for more data.

When data from the netconf server was split into many ssh packages,
the netconf client performed really bad. This is now improved.

In ct_netconfc, if a timer expired 'at the same time' as the server
sent the rpc-reply, the timeout message might already be in the
client's message queue when the client removed the timer ref from its
'pending' list. This caused a crash in the client since the timer ref
could no longer be found when handling the timeout message.

This commit fixes the problem by always flushing the timeout message
from the message queue when canceling a timer.
