b35df4578b Check Registered base class provides virtual destructor
The base class of Registered must provide a virtual destructor to enable
safe deletion with just a base class pointer. This requirement can be
lifted by using Registered_no_delete in places where the deletion
property is not needed.

cb43e04691 ldso: defer execution of static constructors
Ldso now does not automatically execute static constructors of the
binary and shared libraries the binary depends on. If static
construction is required (e.g., if a shared library with constructor is
used or a compilation unit contains global statics) the component needs
to execute the constructors explicitly in Component::construct() via
Genode::Env::exec_static_constructors().

In the case of libc components this is done by the libc startup code
(i.e., the Component::construct() implementation in the libc).

The loading of shared objects at runtime is not affected by this change
and constructors of those objects are executed immediately.

8d68d3d8ac Adapt resource-request test to changes of init
The test used to rely on init's formerly built-in policy of answering
resource requests with slack memory, if available. Since init no longer
responds to resource requests in an autonomous way, we use a dynamically
configured sub-init instance as runtime for the test. This instance, in
turn, is monitored and controlled such that resource requests are
result in quota upgrades. The monitoring component is implemented in
the same test-resource_request program as the test. Both roles are
distinguished by the "role" config attribute.

This is a follow-up to "init: explicit response to resource requests".

1fde4d638c init: service forwarding
This patch equips init with the ability to act as a server that forwards
session requests to its children. Session requests can be routed
depending of the requested service type and the session label
originating from init's parent.

The feature is configured by one or multiple <service> nodes hosted in
init's <config> node. The routing policy is selected by via the regular
server-side policy-selection mechanism, for example:

<config>
  ...
  <service name="LOG">
    <policy label="noux">
      <child name="terminal_log" label="important"/>
    </policy>
    <default-policy> <child name="nitlog"/> </default-policy>
  </service>
  ...
</config>

Each policy node must have a <child> sub node, which denotes name of the
server with the 'name' attribute. The optional 'label' attribute defines
the session label presented to the server, analogous to how the
rewriting of session labels works in session routes. If not specified,
the client-provided label is presented to the server as is.

1489791d5e init: explicit response to resource requests
This patch removes the formerly built-in policy of responding to
resource requests with handing out slack quota. Instead, resource
requests have to be answered by an update of the init configuration with
adjusted quota values.

Note that this patch may break run scripts that depend on init's
original policy. Those run scripts may be adjusted by increasing the
quota for the components that use to inflate their RAM usage during
runtime such that the specified quota suffices for the entire lifetime
of the component.

06943f413d init: respond to RAM-quota changes in config
This patch improves init's dynamic reconfigurability with respect to
adjustments of the RAM quota assigned to the children.

If the RAM quota is decreased, init withdraws as much quota from the
child's RAM session as possible. If the child's RAM session does not
have enough available quota, a resource-yield request is issued to
the child. Cooparative children may respond to such a request by
releasing memory.

If the RAM quota is increased, the child's RAM session is upgraded.
If the configuration exceeds init's available RAM, init re-attempts
the upgrade whenever new slack memory becomes available (e.g., by
disappearing other children).

b3e5357cf1 Adaptation to init refactoring
Since init no longer provides public headers, we have to adjust the
existing users of this headers. The 'init/child_config.h' is used only
by GDB monitor. So the patch moves the header there as an interim fix.
The 'init/child_policy.h' is still used by a few components, so we have
to keep a trimmed-down version of it for now.

9dca1503a8 init: apply changes of <provides> nodes
This patch enables init to apply changes of any server's <provides>
declarations in a differential way. Servers can in principle be extended
by new services without re-starting them. Of course, changes of the
<provides> declarations may affect clients or would-be clients as this
information is taken into account for the session routing.

fcf25c22d1 init: respond to binary-name changes
This patch covers the resolution of the ROM route for child binaries
via the generic label-rewriting mechanics. Now, the <binary> node has
become merely sytactic sugar for a route like the following:

<start name="test"/>
  <route>
    <service name="ROM" unscoped_label="test">
      <parent label="test-binary-name"/> </service>
      ...
  </route>
  ...
</start>

A change of the binary name has an effect on the child's ROM route to
the binary and thereby implicitly triggers a child restart due to the
existing re-validation of the routing.

ec007c0f27 input_filter.run: stabilize key-repeat test
Under certain timing conditions, the test would end up flushing the
input from the input filter in a nested way, which ultimately resulted
in lost input events of the outer nesting level. This patch eliminates
this corner case and thereby stabilizes the key-repeat test.

bf96c7f16e platform/x86: fix quota for local ram session
Transfer quota to the session local RAM session to react to the
Quota_exceeded exception properly.

The platform driver keeps a session local RAM session for each of its
clients that is used to allocate DMA memory. A client needs to transfer
some of its quota to the platform driver, which in return transfers this
quota to the session local RAM session. As it happens allocating memory
from a RAM session involves book keeping and in this case, where the
available quota in the session did not suffice and the request was only
a few KiB, the platform driver handled the exception wrongly and did not
transfer the quota.

This problem did not surface up to now because all drivers allocate DMA
memory in larger chunks and the book keeping overhead was of no
consequence as the initial quota transfer probably covered the overhead.

Fixes #2316.

beb5169ee9 signal test: fix destruction of nested test
The signal_1/2/3 objects (which are threads) are in destruction, but still
signals are send to them. When the signal arrive and the memory for the
signal_1/2/3 object is already invalid we operate on stale memory and all
the locking infrastructure of the Thread don't work anymore.

Be more robust, explicitly wait for the termination of the thread.

b05b5616c8 x86 cpu_quota: lower error tolerance
Previously, on X86, the timer driver used the PIT with a maximum timeout
of 54 ms.  Thus, the driver frequently interrupted the counters with
highest priority to update the timer. This is why we needed a higher
error tolerance as for ARM where the driver, once configured, can sleep
for the whole test timeout. Now, we use the kernel timer and the problem
seems to be exits no longer.

574a1bd198 test/cpu_quota: tolerate errors in session quota
Previously we pre-calculated the translation errors for the session
quota to make a discret check in the test. But since the order, in which
init childs get their CPU quota isn't always the same anymore (we should
have never made assumptions about that) the translation errors differ
from trial to trial. However, the errors are below 0.01% of the super
period. We now tolerate them in the run script.
