7fc20e9ae8 NIC router: update IP config on DHCP RENEW/REBIND
The NIC router did update the IP config of a domain on a completed DHCP
REQUEST but not on completed DHCP RENEW or DHCP REBIND. Thus, it didn't adapt
to "real" DHCP servers (not NIC router servers) that got restarted with a
changed configuration by the means of RENEW/REBIND. The commit fixes this.
Note, that testing this is complicated as we don't have the necessary
infrastructure (we cannot simply use the DHCP server of the NIC router as this
would apply a link down/up sequence in order to let the client restart DHCP)

bb26a986e6 sculpt: add trace_logger as optional launcher
This patch adds the trace-logger utility to the default set of packages
along with an optional launcher. With this change, only two steps are
needed to use Genode's tracing mechanism with Sculpt:

- Add 'trace_logger' to the 'launcher:' list of the .sculpt file

- Either manually select the 'trace_logger' from the '+' menu,
  or add the following entry to the deploy configuration:

    <start name="trace_logger"/>

By default, the trace logger is configured to trace all threads
executed in the runtime subsystem and to print a report every 10
seconds. This default policy can be refined in the launcher's <config>
node. Note that the trace logger does not respond to configuration
changes during runtime. Changes come into effect not before restarting
the component.

trace logger now generates tabular output as follows.

ceb91732bf trace_logger: update state after adding subjects

be0a1742ac base: distinct TRACED from ATTACHED trace subjects
This patch makes the trace-subject state as reflected to the trace
monitor more accurate.

Until now, a subject could be in UNTRACED or TRACED state. In reality,
however, there exists an intermediate state after the trace monitor
called 'trace' for the subject but before the subject locally activated
the tracing (done when passing a trace point). This intermediate state
was reflected as UNTRACED. Consequently, threads that never pass a trace
point (e.g., just waiting for I/O) would remain to appear as UNTRACED
even after enabling its tracing by the trace monitor. This is confusing.

This patch replaces the former UNTRACED and TRACED states by three
distinct states:

  UNATTACHED  prior any call of 'trace'
  ATTACHED    after a trace monitor called 'trace'
              but before the tracing is active
  TRACE       tracing is active

a9022d8451 sandbox: improve CPU-quota accounting
The existing assignment of CPU quotas did not anticipate the dynamic
reconfiguration of init. It merely tracked the available CPU quota by
deducing the consumed amount from a global variable but never
replenished the value. This worked for static scenarios but failed in
situations where components are dynamically re-started.

So far this deficiency remained detected because CPU quotas were not
used in highly dynamic systems like Sculpt OS. However, this has
recently changed by commit "sculpt: assign CPU quotas".

The patch improves the accounting by mirroring the existing handling of
RAM and cap quotas. Note that the CPU-quota accounting is still rather
limited. In particular the dynamic rebalancing is not yet supported.

ca9460aead event_filter: touch/press untouch/release sequence
This commit changes the touch-click filter to adhere the following
sequence:

  touch         (physical)
  press         (artifically generated)
  release       (artificially generated)
  release_touch (physical)

This order is important because nitpicker's focus handling takes
press/release events into account. If the release-touch event appears
before the release event, nitpicker subsumes the release-touch event
to the sequence that started with the press event, instead of handling
it as a free-standing event.

c2efa5406e xml_node: support backslash as attribute value
XML allows attribute values like <node attr="\"/>. The XML parser
wrongly reflects this case as 'Invalid_syntax'. This behavior stems from
the implicit use of the 'end_of_quote' function, which considers the
sequence of '\"' as a quoted '"' rather than the end of a quoted string.

The patch solves this problem by making the 'end_of_quote' part of
the tokenizer's scanner policy.

The patch removes the 'end_of_quote' function from 'util/string.h'
because it is not universal, and to avoid the ambiguity with
'SCANNER_POLICY::end_of_quote'.
