This patch replaces the original policy-based 'update_from_xml' by a new
method that takes three functors for creating, destroying, and updating
elements as arguments. XML nodes are associated with their corresponding
internal data models by annotating the element type with the
'type_matches' class function and the 'matches' method.
The patch also improves safety by enforcing that list-model elements can
never be copied.
Fixes#4317
`Expandind_pd_session_client::try_alloc` is an overriden virtual method
of `Ram_allocator::try_alloc`. The latter specifies the default Cache
argument as CACHED. The overriden method should either do the same or
not even specify a default argument at all.

The 'Xml_node::differs_from' method takes the constructor arguments
(addr, size) for a byte-wise comparison whereas 'with_raw_node'
restricts the byte range to the actual XML tags. In cases where
the XML start tag is preceeded by whitespace, both ranges can differ.
Since the 'differs_from' method is meant for comparing actual XML
nodes - not any whitespace around them - whitespace should be ignored
on both operands.
Issue #5029
Per Affinity::Location a system control cap can be requested. The capability
provides an RPC interface to request and set Cpu_state, as provided by the
former Pd::managing_system(Cpu_state) method. Invocation of those system
control capabilities then *can* (see below) be executed on the desired CPU
as described by Affinity::Location.
The system control cap will be invalid for kernels that don't support
system_control/managing_system functionality at all.
The system control cap will be ever by the same, e.g. ignoring the
Affinity::Location parameter, if the used kernel doesn't support or doesn't
require the feature to execute the system control per CPU.
The commit is a preparation step to add guarded and selective x86 MSR
access per CPU.
Fixes#5009
The new API emphasizes control over the vCPU data by granting access
through the Vcpu::with_state() method, which makes sure that the vCPU is
stopped, invokes the supplied function with a reference to the VM state
and resumes the vCPU if the function returns true.
The old Vcpu::run(), Vcpu::pause() and Vcpu::state() methods are removed
in favor of the new API. Execution of the vCPU is now interrupted by
sending a native Genode Signal to its Vcpu_handler, which will run the
VMM's exit handling method. When this method retrieves the vCPU state by
calling Vcpu::with_state(), the outside interruption is detected and on
x86 a recall exit is injected into the state to signal the vCPU
interruption / pause request to the VMM's vCPU handler.

Depending on the client and use-case the current minimal timeout
value of 5 ms could be too high, lowering it to 1 ms stays within
the limit imposed by most timer drivers.
Issue #4990.
The last character should only be skipped if a `\0` or `\n` is found. If
the string ends without such a character or the maximum line length is
hit, we do not skip the last character.

* Removes the <event> tag from all test package runtime files and replaces the
contained <timeout> and <log> sub-tags with the new tags <succeed> and
<fail>. If a <succeed> or <fail> tag has a content, it defines a log pattern
that should be recognized and render the test failed or successful. If a
<succeed> or <fail> tag has an attribute after_seconds that is not set to 0,
it defines a timeout after which the test should be rendered failed or
successful.
* Adapts the Depot Autopilot to support the new syntax in the test-package
runtime files. However, for now, the Depot Autopilot is kept compatible to
the old syntax as well. If the <events> tag is present, it is prioritized
over the new syntax.

Since component.cc is no longer linked to core, we can also remove
entrypoint.cc, which was merely a dependency of component.cc.

By supplying only the parts of the Env that are actually relevant for
initializing the cxx heap, we avoid the need for the 'Env' interface.
The patch also moves the call of 'init_ldso_phdr' to the outside
of the cxx library because it does not belong there.

By splitting the 'init_capability_slab()' implementation to a separate

This patch replaces the internal use 'env_deprecated()' from the
implementation of the thread API in the base library. It also
replaces the global accessor 'main_thread_cap' by the explicit
propagation of the main-thread's capability to the single point of
use via a new 'init_thread_bootstap' function.

This patch restricts 'Region_map::attach_executable' to create read-only
mappings, while offering the option to map the full rights using a new
'attach_rwx' method.
The 'attach_rwx' method is now used by the dynamic linker to explicitly
attach the linker area with full rwx rights. With the old page-fault
handling code, the execute flag was evaluated only for leaf dataspaces,
not for managed dataspaces while traversing region-map hierarchies.
With the new page-fault handling code, the execute bit is downgraded
to no-execute when passing a managed dataspace that is not attached
as executable.
Issue #4920
The change "core: allow offset-attached managed dataspaces" addressed a
corner case of the use of nested region maps. Apparently, this change
negatively affects other scenarios (tool_chain_auto).
In order to confidently cover all the differnt situations, this patch
reworks the page-fault resolution code for improved clarity and safety,
by introducing dedicated result types, reducing the use of basic types,
choosing expressive names, and fostering constness.
It also introduces a number of 'print' hooks that greatly ease manual
instrumentation and streamlines the error messages printed by core.
Those messages no longer appear when a user-level page-fault handler
is reistered for the faulted-at region map. So the monitor component
produces less noise on the attempt to dump non-existing memory.

This patch moves the destruction of the child's PD session after the
closing of all other sessions because the PD session's role as resource
container might still be needed for orderly reverting the session quotas
when closing the other remaining sessions.
