Introduce controlling entire system trace status feature from dlt-control (#57)

* dlt-control: Provision to control entire system trace status

1. support for setting trace status using wildcards for both app and context
2. support for setting entire system trace status

*This Logic is as same as for changing log level.

 dlt-control: Provision to control entire system log level)

* dlt-daemon: Fix control entire log level / trace status issue

In previous, dlt-control could send request to set
all log level / trace status with DLT_LOG_DEFAULT / DLT_TRACE_STATUS_DEFAULT(-1).
However, dlt-daemon could not accept these value.
This change fix this issue so that setting log level/trace status of
all registered contexts become possible.
