4d7d4dd2fc nova: fix capability issues in PCID/SMP setups 
Kernel fails to lookup a capability it just got delegated, if
the backing store for the destination capability was before backed by a
zero-page. Triggers if PCID (64bit) is in use or in SMP setups.

2cde1d36c1 base: changes for GDB monitor 
- add a new function 'binary_ready_hook_for_gdb()' in ldso. GDB can set a
  breakpoint at this function to know when ldso has loaded the binary
  into memory.
- get the thread state from the NOVA kernel immediately on 'pause()'

c0e88ec69e nova: adjust kernel quota calculation 
Too less memory quota for a PD may be calculated, which leads to too early
punishment for a Genode process.

9506c89f88 nova: fix memory leaks / invariant TSCs 
- free up kernel memory of empty slabs (if already one empty slab is in
  place)
- free up more page table entries
- handle CPUs with invariant TSCs gracefully

  Genode/Nova running on CPUs without the invariant TSC feature may seem
  to 'hang'. The referenced commit of the nova branch fixes the issue
  for some older Intel CPUs.

3e90542559 nova: use signals with irqs in core 
Avoids the need to have per IRQ a thread that blocks synchronously for next
interrupt. Now a thread may wait for multiple IRQs as other signals
simultaneously.

In core no threads are required anymore for IRQs/MSI - the clients (either
the pci_drv or in case of MSI the driver) gets the IRQ delivered directly as
a ordinary Genode signal.

Useful since #1216 and #1487 is now available.
Commit applies feature of #1446 also to IRQ/MSIs.

3279346f80 nova: update kernel (fixes endless loop) 
If running multiple VBox VMMs with Windows as guest concurrently then it may
happen that the system seem to hang. It turned out that actually
a VM-exit storm (vmx_exception->handle_exc_nm) causes a endless loop between
kernel and vCPU. Nothing gets scheduled nor interrupts are received anymore.
The referenced kernel commit fixes this issue.

8842ba2e1c nova: remove timer delay heuristic 
The commit uses a fixed kernel branch (r8), which fixes a caching bug
observable in the Genode host. The quirk detecting the circumstance in the
timer service is obsolete now and is removed.
