On QEMU, NOVA uses the pretty unstable TSC emulation as primary time
source. Thus, timeouts do not trigger with the common precision (< 50
ms). Use an error tolerance of 200 ms for this platform constellation.

Apparently this construct leads to a compiler errors like
error: second operand to the conditional operator is of type ‘void’, but
the third operand is neither a throw-expression nor of type ‘void’
The fast polling test uses one timer session for raw 'elapsed_ms' calls
and another one for potentially interpolated 'curr_time' calls. It then
compares the two results against each other. However, until now, the
test did not consider that the duration of the session construction may
create a remarkable shift between the local times of the two sessions.
This shift is now determined and compensated before doing any
comparison.

The multiple-handlers test was checking if handlers at one signal were
activated in a fair manner. But on Qemu, the error tolerance of one was
too small in rare cases (2 of 100 runs). However, having multiple
handlers for the same signal context can be considered deprecated
anyway. With the recommended Signal_handler wrapper for signal sessions,
you can't use this feature. Thus, we removed the multiple-handlers test.

The recently implemented capability resource trading scheme unfortunately
broke the automated capability memory upgrade mechanism needed by base-hw
kernel/core. This commit splits the capability memory upgrade mechanism
from the PD session ram_quota upgrade, and moves that functionality
into a separate Pd_session::Native_pd interface.

The depot tool did not consistently distinct libraries from regular
targets when handling binary archives. The binary archive of a regular
target is located at <user>/<bin>/<arch>/<name> whereas a library is
located at <user>/<bin>/<arch>/<api>/<name>.
Fixes#2438
We incorrectly used 'unsigned long' (which is 32 or 64 bit depending on
the CPU architecture) for a timestamp (which is always 64 bit) in the
timer-connection implementation.

On platforms were we do not have local time interpolation we can simply
skip the first test stage in the timeout test. This way, we can at least
test the rest.
Fixes#2435
On ARM, we do not have a component-local hardware time-source. The ARM
performance counter has no reliable frequency as the ARM idle command
halts the counter. Thus, we do not do local time interpolation on ARM.
Except we're on the HW kernel. In this case we can read out the kernel
time instead.
