bcc049ceeb nic_router: manipulate port-forwarding port
The new configuration attributes <tcp-forward to_port="123" /> and
<udp-forward to_port="123" /> enable manipulating the destination port of
port-forwarded packets.

304cb290d9 nic_router: rework quota accounting
* Account all RAM/CAP quota of a session except quota for metadata used in
  core. The latter is considered when asking if a session can afford to make
  an operation but it does not get accounted to always be able to pay back all
  quota when a session closes. The general accounting mechanism is moved from
  atop of the allocators down to the level of RAM/RM session operations.
* report statistics about session objects and quota if <report stats="yes"
  quota="yes"/> is configured. (default is yes if <report> is present)

052ed10a17 nic_router.run: fix invalid uplink
Do not generate invalid configurations for the uplink domain anymore. If
some tests are disabled and therefore their routing rules at the uplink
domain would be invalid, spare out these routing rules.

49a3a0e0d0 nic_router: multiple uplinks
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.

9d16169a65 run: remove NIC driver from nic_*.run tests
Instead of having a lot of platform specific quirks in the run test,
and to also test it on platforms currently missing a NIC driver,
this commit removes hardware drivers from the nic_router and
nic_bridge run scripts, and uses the nic_loopback server instead.

edf1f9d849 nic_router: report some useful information
The NIC router can now be configured to periodically send reports.
Configuration example (shows default values):

<config>
	<report interval_sec="5" bytes="yes" config="yes">
</config>

If the 'report' tag is not available, no reports are send.
The attributes of the 'report' tag:

'bytes'        : Boolean : Whether to report sent bytes and received bytes per
                           domain
'config'       : Boolean : Whether to report ipv4 interface and gateway per
                           domain
'interval_sec' : 1..3600 : Interval of sending reports in seconds

cfbd1f0749 nic_router.inc: allow for individual peer names
Previously, the function that returned the XML config for a network test
client/server in the scripts formed the component name of the peer solely
by combining the protocol name, "client" or "server", and a suffix that
is given as argument. However, to group multiple clients together in one
domain via their session label at the NIC router we want peers with the same
name prefix. Thus, the function now simply takes the whole name as argument.

c3853494c8 nic_router: domain-state-verbose flag
When this flag is set in the config tag, the NIC router will print a
short information to the log for each general state change of a domain.
This includes currently the IP-configuration state and the number of
connected NIC sessions. This a useful addition as the normal verbose
flag's purpose is a very deep insight into almost every activity in the
router, which is cool for debugging sophisticated problems but normally
floods the log and therefore discards this option for, e.g., desktop
systems. In such systems, the new verbosity is pretty discreet but
already gives a good hint on why packets may get dropped by the router
although the routing rules are correct.

3cdcb528ff nic_router: advanced timeout configuration

(and still optional) attributes for timeouts used in the NIC router
(these are also the default values):

<config dhcp_discover_timeout_sec="10"
        dhcp_request_timeout_sec="10"
        dhcp_offer_timeout_sec="10"
        udp_idle_timeout_sec="30"
        tcp_idle_timeout_sec="600"
        tcp_max_segm_lifetime_sec="30">

657fa16f8c nic_router: use LwIP- instead of LxIP UDP-tests
Currently, LxIP peers need a lot of RAM (the simple test-client/server for the
nic_router test need at least 28 MB per component). As the nic_router test
previously used 6 instances of such components and a lot of other components,
it had issues with insufficient RAM on some platforms. By using two new
LwIP-based UDP tests instead, we save more than 100 MB.

8ab0a5c795 nic_router.run: avoid use of 'string cat'
It seems that our buildbot has a problem with the TCL command 'string
cat'. In most cases it is not necessary anyway as we can use the ""
enclosure instead. It unfolds inline procedure calls and variables
automatically. We don't want to use "" only in cases where the literal
shall contain many " characters itself as it is the case for XML
configs. Then we use the 'append' command and a helper variable instead.

4da52517c1 Simpify startup of dynamically linked binaries
This patch removes the component_entry_point library, which used to
proved a hook for the libc to intercept the call of the
'Component::construct' function. The mechansim has several shortcomings
(see the discussion in the associated issue) and was complex. So we
eventually discarded the approach in favor of the explicit handling of
the startup.

A regular Genode component provides a 'Component::construct' function,
which is determined by the dynamic linker via a symbol lookup.
For the time being, the dynamic linker falls back to looking up a 'main'
function if no 'Component::construct' function could be found.

The libc provides an implementation of 'Component::construct', which
sets up the libc's task handling and finally call the function
'Libc::Component::construct' from the context of the appllication task.
This function is expected to be provided by the libc-using application.
Consequently, Genode components that use the libc have to implement the
'Libc::Component::construct' function.

The new 'posix' library provides an implementation of
'Libc::Component::construct' that calls a main function. Hence, POSIX
programs that merely use the POSIX API merely have to add 'posix' to the
'LIBS' declaration in their 'target.mk' file. Their execution starts at
'main'.

5a1cef6381 Make label prefixing more strict
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).
