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

This function returns the information whether the used platform relies
on USB HID for interactive scenarios by default as is the case for most
ARM platforms. In contrast, for x86 the USB driver can be omitted because
we can use the PS/2 driver (that is readily available in repos/os/).
* get rid of printf
* use exceptions instead of error codes
* use Id_space instead of the individual block device registry
* use Cstring instead of char const*
* move method definitions > 1 line to .cc files
* rename Block Block_driver and Serial Serial_driver to avoid name clashes
with the Genode namespace and thereby simplify the code
* use lambdas for Block device lookup and apply
* switch to the Component framework
* don't use env(), config(), ... and hand over env to each connection
* use Attached_mmio and Attached_rom/ram_dataspace instead of manual
solutions
Fixes#2223
The init component used to create the CPU/RAM/PD/ROM sessions (the child
environment) for its children by issuing session requests to its parent,
which is typically core. This policy was hard-wired. This patch enables
the routing of the environment sessions of the children of init
according to the configured routing policy.
Because there is no hard-wired policy regarding the environment sessions
anymore, routes to respective services must be explicitly declared in
the init configuration. For this reason, the patch adjusts several run
scripts in this respect.
This patch removes the outdated '<if-args>' special handling of session
labels. The '<if-args>' feature will eventually be removed completely
(ref #2250)

Most implementations use a Signal_handler now to acknowledge the packet
instead of waiting for the transfer completion. The exceptions to that are
the non-DMA implementations for RPI and PL180
Ref #2206
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).

Limit the number of generations to 4 to prevent hitting the
socket-descriptor limit on Linux. Also, all possible configuration
parameters for bomb our now customizable in the run script and the
current config is logged by bomb master.
This patch is a preparation of the forthcoming async parent interface.
Note that this patch increases the size of connection objects.
Furthermore it adds a diagnostic message whenever a connection fails.

Issue #2060
Besides adapting the components to the use of base/log.h, the patch
cleans up a few base headers, i.e., it removes unused includes from
root/component.h, specifically base/heap.h and
ram_session/ram_session.h. Hence, components that relied on the implicit
inclusion of those headers have to manually include those headers now.
While adjusting the log messages, I repeatedly stumbled over the problem
that printing char * arguments is ambiguous. It is unclear whether to
print the argument as pointer or null-terminated string. To overcome
this problem, the patch introduces a new type 'Cstring' that allows the
caller to express that the argument should be handled as null-terminated
string. As a nice side effect, with this type in place, the optional len
argument of the 'String' class could be removed. Instead of supplying a
pair of (char const *, size_t), the constructor accepts a 'Cstring'.
This, in turn, clears the way let the 'String' constructor use the new
output mechanism to assemble a string from multiple arguments (and
thereby getting rid of snprintf within Genode in the near future).
To enforce the explicit resolution of the char * ambiguity, the 'char *'
overload of the 'print' function is marked as deleted.

Core on seL4 is configured to run on native hardware, so some static
allocators are bit over dimensioned. Some run scripts fail on qemu because
solely 64M are available in the system - adjust the affected scripts.

This patch integrates three region maps into each PD session to
reduce the session overhead and to simplify the PD creation procedure.
Please refer to the issue cited below for an elaborative discussion.
Note the API change:
With this patch, the semantics of core's RM service have changed. Now,
the service is merely a tool for creating and destroying managed
dataspaces, which are rarely needed. Regular components no longer need a
RM session. For this reason, the corresponding argument for the
'Process' and 'Child' constructors has been removed.
The former interface of the 'Rm_session' is not named 'Region_map'. As a
minor refinement, the 'Fault_type' enum values are now part of the
'Region_map::State' struct.
Issue #1938
Prevents the annoying warning about
WARNING: Image format was not specified for 'bin/test.img' and probing guessed raw.
Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
Specify the 'raw' format explicitly to remove the restrictions.
This driver uses the Usb session interface and provides a Block session
to its client. See _repos/os/src/drivers/usb_block/README' for more
information.
Fixes#1885.
