* Remove SPEC declarations from mk/spec
* Remove all board-specific REQUIRE declaratiions left
* Replace [have_spec <board>] run-script declarations with have_board where necessary
* Remove addition of BOARD variable to SPECS in toplevel Makefile

Let the NIC router provide an Uplink service besides the Nic service that it
already provided. Requests for an Uplink session towards the NIC router are
assigned to Domains using the same <policy> configuration tags that are used in
order to assign Nic session requests. The MAC addresses of Uplink session
components are _NOT_ considered during the allocation of MAC addresses for NIC
session components at the same Domain. The task of avoiding MAC address clashes
between Uplink session components and Nic session components is therefore left
to the integrator. Apart from that, Uplink session components are treated by
the NIC router like any other interface.

Right now the same code dealing with nic setup on qemu is duplicated
in many different run scripts. It makes it unnecesarily complex to
change the existing config or add support for new nic types. Lets move
all this common code to qemu.inc.

Introduce the managing_system privilege for components like the
platform_driver to allow it to call system management functionality
that is reserved by kernel or special firmware, e.g., ARM Trusted Firmware.
The former RAM resource configuration attribute `constrain_phys`,
which enabled to constrain the region of physical RAM to be used,
gets replaced by the new, broader managing_system configuration
attribute of a `start` node. It gets enforced by the sandbox library.

The zynq nic_drv also depends on hw, we therefore adapted the folder
structure for clarity. Also renamed the binary to 'zynq_nic_drv' to
prevent conflicts and to allow removing the cadence_gem spec.
Issue #3179
Since the timer and timeout handling is part of the base library (the
dynamic linker), it belongs to the base repository.
Besides moving the timer and its related infrastructure (alarm, timeout
libs, tests) to the base repository, this patch also moves the timer
from the 'drivers' subdirectory directly to 'src' and disamibuates the
timer's build locations for the various kernels. Otherwise the different
timer implementations could interfere with each other when using one
build directory with multiple kernels.
Note that this patch changes the include paths for the former os/timer,
os/alarm.h, os/duration.h, and os/timed_semaphore.h to base/.
Issue #3101
Introduce the uplink tag:
! <config>
! <uplink label="wifi" domain="uplink">
! <uplink label="wired" domain="wired_bridge">
! <uplink domain="wired_bridge">
! <config/>
For each uplink tag, the NIC router requests a NIC session with the
corresponding label or an empty label if there is no label attribute.
These NIC sessions get attached to the domain that is set in their
uplink tag as soon as the domain appears. This means their lifetime is
not bound to the domain. Uplink NIC sessions can be safely moved from
one domain to another without being closed by reconfiguring the
corresponding domain attribute.
Attention: This may render previously valid NIC router configurations
useless. A domain named "uplink" doesn't automatically request a NIC
session anymore. To fix these configurations, just add
! <uplink domain="uplink"/>
or
! <uplink label="[LABEL]" domain="uplink"/>
as direct subtag of the <config> tag.
Issue #2840
On Linux, we have a tap device as NIC back end but there is no one to
ping to in the subnet of the tap device. On FOC, the tests seem to trigger
a bug in the destruction of components with parent.exit(X); .
Fixes#2848
This tests the case that behind a NIC router domain there are not only
directly connected clients of the subnet but also Layer 2 indirections like
a switch or a bridge which might be interesting for example for testing the
NIC routers DHCP server implementation.
Fixes#2837
On real hardware, the tests expect an IPv4 subnet such that UDP requests
to 10.0.0.2 port 12345 get answered with an ICMP destination port unreachable.

Set DHCP discover timeout to 1 second because, for some reason, the first
DHCP discover attempt of the NIC router on the PandaBoard times out with the
nightly test infrastructure.
Issue #2788
Adaption to mac-address allocation changes
Instead of handing over the maximum available size to the packet data
accessors, hand over a size guard that keeps track of the packets
boundaries.
This commit also moves the size-guard utilitiy header of Ping and NIC
Router to the include/net directory making it a part of the net library.
It applies the new approach to all net-lib users in the basic repositories.
Ping looses its configurability regarding the ICMP data size as this would
require an additional method in the size guard which would be used only by
Ping.
The size guard was also re-worked to fit the fact that a packet can
bring a tail as well as a header (Ethernet).
Issue #2788
This tests ping with simple IP forwarding, ping with NAPT as well as
forwarding of ICMP "Destination Unreachable" messages through the NIC
router.
