Inject SIGTRAP for manual stop
...
Instead of fighting against the normal flow, just signal a SIGTRAP and
let the existing flow handle it, as long as we set the halt flag
correctly the system should halt.

Fix: Linux - call wait4 on thread grp leader is broken

that is ptraced and that was survived by its children.

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.

Optimize Next implementation
...
Once the program detects that we have stepped into another function,
we simply calculate the return address and then set a breakpoint and
continue to that location, avoiding numerous syscalls.

Implement basic api for figuring out, given a current PC value, where
the function will return. Currently the API provides only a way to
determine the offset from SP (the Canonical Frame Address). It is left
up to the caller to grab the actual address from the traced program.
