Fix: do not always use pid thread for clearing bp
...
Since fixing scheduler handling bugs, a new bug was exposed where Step
was calling Clear off of the DebuggedProcess struct. This is incorrect,
and should be handled by the thread itself and not delegated.

Use allm info to attach to existing threads
...
This remove reliance on the procfs for figuring out what threads are
already active when we attach to a running process. The allm linked list
will be present to matter what OS we're on, whereas procfs will not be
present everywhere.
This is the first in a series of steps to support more platforms.

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.

Refactor: wrap syscall.Wait4

Wrap syscall.Wait4 and cleanup a few coordination issues.
There are still some issues here where background threads are left
sleeping. This could potentially cause weird issues. There are a few
more things I have planned to cleanup thread coordination issues.
