Some hw breakpoint fixes
...
Enable usage of dr1-dr3. Clear control bits when a breakpoint
is disabled. Use DR_LEN_1 instead of DR_LEN_8 so breakpoint work on
unaligned adresses.
Fixes #51 .

Improve support for goroutine context switching
...
Remove any assumption that a wait syscall on a thread id after a
continue will return. Any time we continue a thread, wait for activity
from any thread, because the scheduler may well have switched contexts
on us due to syscall entrace, channel op, etc...
There are several more things to be done here including:
* Potential tracking of goroutine id as we jump around to thread
contexts.
* Potential of selectively choosing threads to operate on based on the
internal M data structures, ensuring that our M has an active G.
This commit partially fixes #23 and #24 , however there are still some
random hangs that happen and need to be ironed out.
