For all tests
* use Component::construct instead of main
* use new connection constructors with env argument
* use log instead of printf
For some tests
* replace signal receivers with signal handlers
* replace global static variables with Main class members
* remove unnecessary multithreading
* model test steps as classes that are independent from each other and managed
by Main as constructibles
* use references instead of pointers and exceptions instead of error codes
* use Attached_* helpers intead of doing attach/detach manually
* use helpers like String, Id_space, Registry instead of arrays and lists
* make the run script suitable for automated execution and conclusion
Ref #1987
This patch unconditionally applies the labeling of sessions and thereby
removes the most common use case of 'Child_policy::filter_session_args'.
Furthermore, the patch removes an ambiguity of the session labels of
sessions created by the parent of behalf of its child, e.g., the PD
session created as part of 'Child' now has the label "<child-name>"
whereas an unlabeled PD-session request originating from the child
has the label "<child-name> -> ". This way, the routing-policy of
'Child_policy::resolve_session_request' can differentiate both cases.
As a consequence, the stricter labeling must now be considered wherever
a precise label was specified as a key for a session route or a server-
side policy selection. The simplest way to adapt those cases is to use a
'label_prefix' instead of the 'label' attribute. Alternatively, the
'label' attribute may used by appending " -> " (note the whitespace).
