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

In the past, the Genode::destroy, that is called by the RAM-FS-chunk destructors,
issued Allocator::free instead of the C++ delete. Therefore it was possible to
use the size argument of Allocator::free for the allocation tracker in the
RAM-FS-chunk test. Nowadays, we have to keep track of the allocation sizes
ourselves because delete doesn't hand over the size.

The FB Block Adapter in os/src/test visualizes a block session via a
Framebuffer session. As far as I can see, it is not a test but rather
the base for a bump-in-the-wire component. However, for this role it
currently lacks a Block back-end. As it also would have to be updated to
use the new base API I removed it instead, leaving only its git
history as inspiration if someone needs such a component in the future.

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)

This patch changes the 'Xml_node_label_score' to regard an empty
label_prefix or label_suffix as a match instead of a conflict. Until
now, there was no use case for an empty label_prefix. But with init's
new ability to route environment sessions, an empty prefix denotes any
child-initiated session (as oposed to an parent-initiated environment
session).

To better support non-blocking terminal components, let the
'Terminal::Session::write()' function return the number of bytes
actually written.
Fixes#2240
The session-control mechanism is based on the way how sessions are
labeled. In #2171, we changed the labeling to be more strict. In
particular, label-less sessions do no longer exist.
Unfortunately, nitpicker and the window manager still handled the former
weaker labeling, which ultimately led to a situation where any
session-control argument would mismatch. The behavior could be observed
in the launcher.run script where a click on the subsystem button would
not focus the clicked-on subsystem. With the patch, the scenario works
again as expected.
This patch enables warnings if one of the deprecate functions that rely
in the implicit use of the global Genode::env() accessor are called.
For the time being, some places within the base framework continue
to rely on the global function while omitting the warning by calling
'env_deprecated' instead of 'env'.
