85001a7cc6 * Fixed checking for DR6 bits after a debug exception (we were and'ing
with the bit number, not the respective mask).
* Added a small hack to allow single stepping to work in qemu.
  Apparently the BS bit in DR6 is not set when the debug exception
  is handled. So we always assume that a single step event occurred,
  when we couldn't recognize any other event, if the hack is enabled.

86cc722477 * DR3 is used for holding the pointer to the current struct thread*, so
we only have 3 debug registers available for break-/watchpoints.
* Added definitions for debug status register DR6. Reordered DR7 defs to
  ascending order. Added definitions for the EFLAGS flags we need.
* Added arch_thread_debug_info structure and related definitions.
