trace_logger: avoid output of empty lines

It avoids output of empty lines in output buffer if traced messages end
with \n (what is common with messages logged from dde_linux).

trace_logger: convenient tracing frontend

The 'trace_logger' component can be used to easily gather, process and export
different types of tracing data. Which subjects to select is configurable via
session label policies and thread names. Which data to collect from the
selected subjects can be configured for each subject individually, for groups
of subjects, or for all subjects. The gathered data can be exported as log
output.

This is an example configuration of the 'trace_logger' component which shows
the default value for each attribute except the policy.thread and
policy.label:

! <config verbose="no"
!         session_ram="10M"
!         session_arg_buffer="4K"
!         session_parent_levels="0"
!         period_sec="5"
!         activity="no"
!         affinity="no"
!         default_policy="null"
!         default_buffer="4K">
!
!    <policy label="init -> timer" />
!    <policy label_suffix=" -> ram_fs" />
!    <policy label_prefix="init -> encryption -> "
!            thread="worker"
!            buffer="4K"
!            policy="null" />
! </config>
