At least on foc_x86_64, nic_router refused to create sessions for the
test clients as the session object's size exceeds the old quota
donation.

Both methods are now available for Ipv4_address as well as for
Ipv4_address_prefix. An IPv4 address is invalid if it contains zeros only.
An IPv4 address prefix is invalid if its address is invalid and its
prefix is 32.

Instead of creating one socket and re-using it each test run because the
client shall also test the termination of pseudo-connections at components that
implement hole punching for UDP.

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).
Fixes#2171
The log plugin can now be configured to request a log session with the
specified label like follows.
<log label="..."/>
Per default, no new log session is requested but the existing log
session of the component's environment is used.
The heap typically first tries to allocate larger chunks than necessary, and
if it fails the actual minimal one. The first attempt already triggers warnings
which are not critical at all. If the second (critical) allocation fails,
then there are additionally checks and warnings already in place.
Issue #1039
Trace_control dataspace gets destroyed implicitly when the cpu session is
closed. Remove the trace control dataspace from the internal noux dataspace
registry before cpu session destruction.
The code in Core's Cpu_session_component::create_thread might throw a
capability refernce-count overflow if one creates many threads, which would
kill core if not handled.
Ref #2120
This patch adjusts the various users of the 'Child' API to the changes
on the account of the new non-blocking parent interface. It also removes
the use of the no-longer-available 'Connection::KEEP_OPEN' feature.
With the adjustment, we took the opportunity to redesign several
components to fit the non-blocking execution model much better, in
particular the demo applications.
