The initial ROMs (program and linker) are already attached to the region
map of a forked process and don't need to be obtained again from an
external ROM service when the 'Child' class asks for them. For the program
image, the local Noux ROM service already returned an invalid dataspace
capability, but not for the linker.
Instead of adding another 'magic' ROM name for the local ROM service,
this commit implements an 'empty' ROM service, which returns an
invalid dataspace for the initial ROMs.
Fixes#2272
The file space demand for the object files when compiling core has grown.
Therefore, the ram_fs component runs out of memory and requests additional
memory from init. On OKL4, where the physical memory is limited by the
elfweaver bootstrap tool, there is no more slack memory after the donation
of 1G to noux.
Otherwise it may happend that the Guest tries to set the last stored
resolution from another run, which maybe is too large.
Up to now, everthing is fine, beside the fact that output changes are not
visible - which is odd and one things the VM came not up.

that happened during early bootup.
The signal about input events may arrive before keyboard and mouse is set
(due wait_and_dispatch_one_signal called from a started pthread and ep still
not done with the initialisation)
Issue #2306
This commit includes changes to the Nic::Session_component interface.
We now pass the entire env to the component instead of only ram, rm and
the ep because we need the env to open connections from within the
Session_component implemenation. So far only the cadence_gem driver
needs this, though.

broken due to changes of
libc: API transition
Issue #1987
For now provide a initial memory buffer for allocation of static
constructors and of malloc calls out of the libc during early
libc initialization until actual vbox code is executed having the Env
pointer.
The support has two parts. First, a VFS plugin now gets passed an
I/O-response handler callback on construction, which informs users of the
VFS that an I/O event occurred. This enables, for example, the libC to
check if blocking read can be completed. Further, the VFS file I/O
interface provides now functions for suspendable reads, i.e.,
queue_read() and complete_read().
The test now forks twice - the parent forks a child and the child itself
forks a grand child. Both, parent and child, wait for termination of
their forked process with waitpid(). Additionally, the run script now
checks for exit of the parent (not any noux process).
This commit enables compile-time warnings displayed whenever a deprecated
API header is included, and adjusts the existing #include directives
accordingly.

lesskey and lessecho missed the declaration of ${LIBS} on the compiler
command line, which ended up in unusable programs.

Unfortunately, this simple fix renders both tools also dependent to libm
and ncurses which they don't use.
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/).
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

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'.
Issue #1987
This patch removes the dependency of the deprecated Genode API,
fixes the coding style, and removes the "random" file system
(superseded by the VFS plugin mechanism).
