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.

Hafiz Abid Qadeer 01db53848e Added a missing call to 'Reset'.
HostThreadWindows::Join() did not call the Reset as is done by
the HostThreadPosix::Join(). As a result, future call to 
IsJoinable() can fail.

Committed as obvious.

Zachary Turner 172d37d3b9 Create a process launcher abstraction.
This implements Host::LaunchProcess for windows, and in doing so
does some minor refactor to move towards a more modular process
launching design.

The original motivation for this is that launching processes on
windows needs some very windows specific code, which would live
most appropriately in source/Host/windows somewhere.  However,
there is already some common code that all platforms use when
launching a process before delegating to the platform specific
stuff, which lives in source/Host/common/Host.cpp which would
be nice to reuse without duplicating.

This commonality has been abstracted into MonitoringProcessLauncher,
a class which abstracts out the notion of launching a process using
an arbitrary algorithm, and then monitoring it for state changes.

The windows specific launching code lives in ProcessLauncherWindows,
and the posix specific launching code lives in ProcessLauncherPosix.
When launching a process MonitoringProcessLauncher is created, and
then an appropriate delegate launcher is created and given to the
MonitoringProcessLauncher.

Zachary Turner b2df30d652 Fix deadlock in Python one-line execution.
Python one-line execution was using ConnectionFileDescriptor to do
a non-blocking read against a pipe.  This won't work on Windows,
as CFD is implemented using select(), and select() only works with
sockets on Windows.

The solution is to use ConnectionGenericFile on Windows, which uses
the native API to do overlapped I/O on the pipe.  This in turn
requires re-implementing Host::Pipe on Windows using native OS
handles instead of the more portable _pipe CRT api.

This is the first step in getting ConnectionFileDescriptor ported

windows. This supports connection strings of the form file://PATH
which are currently supported only on posix platforms in
ConnectionFileDescriptor.

Zachary Turner 97a14e60b2 Move some Host logic into HostInfo class.
This patch creates a HostInfo class, a static class used to answer
basic queries about the host platform.  As part of this change,
some functionality is moved from Host to HostInfo, and relevant
fixups are performed in the rest of the codebase.

This is part of a larger effort to isolate more code in the Host
layer into platform-specific groups, to make it easier to make
platform specific changes for a particular Host without breaking
other hosts.

More specifically, this change can be summarized as follows:
1) Makes an lldbHostPosix library which contains code common to

2) Creates Host/FileSystem.h which defines a common FileSystem
   interface.
3) Implements FileSystem.h in Host/windows and Host/posix.
4) Creates Host/FileCache.h, implemented in Host/common, which
   defines a class useful for storing handles to open files needed
   by the debugger.

lldb -P, which outputs its python path, works by using Host-layer

Host functionality was unimplemented on Windows, so this patch
implements it.  Additionally, it removes a pexpect dependency from
the test runner and uses an equivalent invocation of subprocess.

* Certain types of filtering are not enabled (e.g. filtering by

* The username of the process is not yet obtained.
* Using -v to list verbose information generates an error.
* The architecture column displays the entire triple, leading to
