Zachary Turner 301d184784 Load / unload modules in the target when the OS events occur.
This causes all deferred breakpoints to be correctly resolved as
the modules that they reside in are loaded.

Zachary Turner 82da55fe57 Disable GetSTDOUT, GetSTDERR, and PutSTDIN on Windows.
These methods are difficult / impossible to implement in a way
that is semantically equivalent to the expectations set by LLDB
for using them.  In the future, we should find an alternative
strategy (for example, i/o redirection) for achieving similar
functionality, and hopefully deprecate these APIs someday.

Zachary Turner 119767db85 [ProcessWindows] Create a TargetThreadWindows class.
This creates a TargetThreadWindows class and updates the thread
list of the Process with the main thread.  Additionally, we
fill out a few more overrides of Process base class methods.  We
do not yet update the thread list as threads are created and/or
destroyed, and we do not yet propagate stop reasons to threads as
their states change.

Zachary Turner a32d2cecba [ProcessWindows] Improve support for launching processes.
This sends notifications for module load / unload to the process
plugin, and also manages the state more accurately during the
loading sequence.

Similar work by Virgile Bello was referenced during the
implementation of this patch.

Zachary Turner d6a7b63f26 [ProcessWindows] Simplify the DebugDelegate interface.
Due to a previous multi-threaded design involving message
passing, we used message classes to pass event information
to the delegate.  Since the multi-threaded design has gone
away, we simplify this by passing event arguments as direct
function parameters, which is more clear and easier to
understand.

Zachary Turner dcd80377f3 [ProcessWindows] Implement breakpoint stop / resume on Windows.
This patch implements basic support for stopping at breakpoints
and resuming later.  While a breakpoint is stopped at, LLDB will
cease to process events in the debug loop, effectively suspending
the process, and then resume later when ProcessWindows::DoResume
is called.

As a side effect, this also correctly handles the loader breakpoint
(i.e. the initial stop) so that LLDB goes through the correct state
sequence during the initial process launch.

Zachary Turner 02862bc83a Remove the top-level DebugDriverThread in ProcessWindows.
Originally the idea was that we would queue requests to a master
thread that would dispatch them to other slave threads each
responsible for debugging an individual process.  This might make
some scenarios more scalable and responsive, but for now it seems
to be unwarranted complexity for no observable benefit.

Zachary Turner 742346a22f Decouple ProcessWindows from the Windows debug driver thread.
In the llgs world, ProcessWindows will eventually go away and
we'll implement a different protocol.  This patch decouples
ProcessWindows from the core debug loop so that this transition
will not be more difficult than it needs to be.

Zachary Turner 8f21174700 Implement a framework for live debugging on Windows.
When processes are launched for debugging on Windows now, LLDB
will detect changes such as DLL loads and unloads, breakpoints,
thread creation and deletion, etc.

These notifications are not yet propagated to LLDB in a way that
LLDB understands what is happening with the process.  This only
picks up the notifications from the OS in a way that they can be
sent to LLDB with subsequent patches.
