5a1cef6381 Make label prefixing more strict
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

f184118930 vfs: support label attribute in log file system
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.

b8f9f92731 base: remove allocation warning in heap
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.

b44f0554bd Adapt high-level components to new parent API
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.

cfdbccc5c2 Remove blocking calls from root and parent RPCs
This is a redesign of the root and parent interfaces to eliminate
blocking RPC calls.

- New session representation at the parent (base/session_state.h)
- base-internal root proxy mechanism as migration path
- Redesign of base/service.h
- Removes ancient 'Connection::KEEP_OPEN' feature
- Interface change of 'Child', 'Child_policy', 'Slave', 'Slave_policy'
- New 'Slave::Connection'
- Changed child-construction procedure to be compatible with the
  non-blocking parent interface and to be easier to use
- The child's initial LOG session, its binary ROM session, and the
  linker ROM session have become part of the child's envirenment.
- Session upgrading must now be performed via 'env.upgrade' instead
  of performing a sole RPC call the parent. To make RAM upgrades
  easier, the 'Connection' provides a new 'upgrade_ram' method.

513a3f1d37 base: new 'Id_space' data structure
This data structure allows the association of objects with IDs. IDs are
kept in an AVL tree. So in contrast to a bit allocator, the ID space can be
sparsely populated and does not need to be dimensioned. The lifetime of
an ID is bound to an 'Element' object, which relieves the programmer
from manually allocating/deallocating IDs for objects.

9ba7b2edde vbox: improve network backend
VirtualBox mainly derives the initial link-state for its device models
from checking the <Adapter ... cable="true"/> attribute. Our backend
only propagates the current state of the Nic session if it receives a
link-state signal. This may lead to problems if a guest detects a link
up state when it is actually down and wants to use the interface. The
backend now queries the Nic session and sets the link-state accordingly
when it is constructed.

In case there is no link do not attempt to submit a packet to the packet
stream but return with an error so that upper layers can handle it.

Enable signals for network on poweron and not already during
construction. The network model may be not yet ready to process incoming
signals and data.

Fixes #2117.

7fba39831a platform_drv/x86: remove device slab
Because of the session-argument buffering added to 'Connection' objects
when changing the parent interface to be non-blocking, the
'Device_component' has grown in size from 1.5 KiB to 5 KiB. The slab
allocator was configured with a block size of 4 KiB. So it does not work
with the grown 'Device_component' size.

Once the transition to the new API is completed (when we can remove the
buffering of session arguments from the 'Connection' objects), we may
revert this change.
