Added the equivalent of gdb's "unwind-on-signal" to the expression command, and a parameter to control it in ClangUserExpression, and on down to ClangFunction.

Moved expression evaluation from CommandObjectExpression into
ClangUserExpression::Evaluate () as a public static function so anyone can
evaluate an expression.

Add "-o" option to "expression" which prints the object description if available.

Fixed the way set/show variables were being accessed to being natively
accessed by the objects that own the settings. The previous approach wasn't
very usable and made for a lot of unnecessary code just to access variables
that were already owned by the objects.

While I fixed those things, I saw that CommandObject objects should really
have a reference to their command interpreter so they can access the terminal
with if they want to output usaage. Fixed up all CommandObjects to take
an interpreter and cleaned up the API to not need the interpreter to be
passed in.

Fixed the disassemble command to output the usage if no options are passed
down and arguments are passed (all disassebmle variants take options, there
are no "args only").

Small help text fixes, to make it more consistent and accurate.

Temporarily remove -l option from 'expr' command (at Sean's request).

Modified CommandObjectExpression::EvaluateExpression() so that it takes an
additional (ComandReturnObject *) result parameter (default to NULL) and does
the right thing in setting the result status.

Removed the -i option from the expr command, and
made IR-based expression evaluation the default.

Also added a new class to hold persistent variables.
The class is empty as yet while I write up a design
document for what it will do. Also the place where
it is currently created (by the Expression command)
is certainly wrong.

Added the temporary -i option to expr, which
switches the expression parsing over to use the
LLVM IR as opposed to Clang ASTs. Right now,
that functionality only logs.

Very large changes that were needed in order to allow multiple connections
to the debugger from GUI windows. Previously there was one global debugger
instance that could be accessed that had its own command interpreter and
current state (current target/process/thread/frame). When a GUI debugger
was attached, if it opened more than one window that each had a console
window, there were issues where the last one to setup the global debugger
object won and got control of the debugger.

To avoid this we now create instances of the lldb_private::Debugger that each
has its own state:
- target list for targets the debugger instance owns
- current process/thread/frame
- its own command interpreter
- its own input, output and error file handles to avoid conflicts
- its own input reader stack

So now clients should call:

SBDebugger::Initialize(); // (static function)

SBDebugger debugger (SBDebugger::Create());
// Use which ever file handles you wish
debugger.SetErrorFileHandle (stderr, false);
debugger.SetOutputFileHandle (stdout, false);
debugger.SetInputFileHandle (stdin, true);

// main loop

SBDebugger::Terminate(); // (static function)

SBDebugger::Initialize() and SBDebugger::Terminate() are ref counted to
ensure nothing gets destroyed too early when multiple clients might be
attached.

Cleaned up the command interpreter and the CommandObject and all subclasses
to take more appropriate arguments.
