Christian Prochaska 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()'

Fixes #1968

* \date 2016-03-11
*
* On most platforms, the 'Genode::Native_thread' type is private to the
* base framework. However, on NOVA, we make the type publicly available to
* expose the low-level thread-specific capability selectors to user-level
* virtual-machine monitors (Seoul or VirtualBox).
