cobalt/synch: Clear PP boost prior to handing over the ownership

Otherwise we first add the synch object to the new owner's boost list
before we remove it from the old one's, corrupting the list.

net: create sysfs nodes for net devices

Each rtnet device registered with the stack is represented by a node
into /sys/devices/virtual/rtnet/.

Setting the address of the real device probed by the kernel into the
rtnet_device.sysbind field before calling rt_register_rtnetdev(),
causes the "adapter" symlink to be installed in the newly created
attribute directory, pointing at that device.

e.g.

static int probe_handler(struct pci_dev *pdev, const struct pci_device_id 
*ent)
{
...
rtdev->sysbind = >dev;
...
ret = rt_register_rtnetdev(rtdev);
...
}

total 0
drwxr-xr-x2 root root 0 Mar 30 12:50 enp1s0
drwxr-xr-x2 root root 0 Mar 30 12:50 rtlo

Revert "copperplate/heapobj-pshared: fix memory limit"

This reverts commit 5b0c3677fa15397ab7d8e609685f8b4259d62fde which was
wrong and fortunately did not survive the upcoming memcheck tests.

cobalt/rtdm: Increase RTDM_MAX_MINOR to 4096 form 1024

Increase the number of RTDM devices that are allowed to be registered to 4096 
to allow gpio drivers with higher pin numbers to be able to register in rtdm 
space.
