* isatty
For the moment it is not possible to determine if the fd belongs to a
tty. For whatever reasons, the check is done multiple times, e.g.
'tclsh', which will spam the LOG.
* sysctl(HW_FLOATINGPT)
FPU is enabled on all our platforms, so return true.
Fixes#3389.
Start and stop the DHCP state machine as the Nic link-state changes.
Invoke the link state handler during configuration rather than assume
that in the case of a downed link lwIP will defer DHCP until the link
comes up.
Additionally, support static DNS configuration via the "nameserver"
configuration attribute.
Fix#3388
This commit updates the tool-chain information, pointing at the
versioned install path now.
It also removes historic information that is no longer of interest.
It might happen, in CPU intensive tests (like TCP bulk lxip), or when
printing debugging output after a failed test (as done currently on
staging), that the run script on the host gives up and reboots the
platform too early. Thus, we raise the buffer time. A reboot should
be necessary only in rare cases anyway.
Fixes#3387
On muen, we don't have configured access to wifi so far. Thus, the wifi
driver doesn't come up and we should skip tests using this driver for
the platform.
Fix#3384
On x86 the CPU count is determined through ACPI's MADT by counting the
local APICs reported there. Some platforms report more APICs
than there are actual CPUs. These might be physically disabled CPUs.
Therefore, a check if the LAPIC is actually physically enabled in
hardware fixes this issue.

fixes#3376
Fix initial stack pointer alignment for x86_64 in crt0.s startup code of
bootstrap. SysV ABI states that upon function entry (rsp + 8) % 16 = 0.
There, we have to align the stack to 16 bytes before all 'call'
instruction not 8. Otherwise FPU (GP) exception might be raised later on
because of unaligned FPU accesses.
issue #3365
Since gcc 8.3.0 generates SSE instructions into kernel code, the
kernel itself may raise FPU exceptions and/or corrupt user level FPU
contexts thereby. Both things are not feasible, and therefore, lazy FPU
switching becomes a no go for base-hw because we cannot avoid FPU
instructions because of the entanglement of base-hw, base, and the tool
chain (libgcc_eh.a).
issue #3365
This patch handles a few corner cases that appear in the headers of
Genode 19.05, in particular the new client-side block API in
'block_session/connection.h'.
