-S : Specifies a command file which will get sourced after the ~/.lldbinit but before file arguments are processed
-O : Specifies a single (one-line) command that will get ditto
and
-s : Specifies a command file which will get sourced after `pwd`/.lldbinit
-o : Specifies a command file which ditto
I also changed it so that by default these sourced commands will print their command result, but there's a
-q option to change that if you wish.

The "lldb" driver was interfering with STDOUT and STDERR if the output was over 1024 charcters long. The output was grabbing 1024 characters at a time, before it output the characters, it was writing characters to the screen to clear the current line. This has been fixed.
I also fixed the command interpreter from mixing the "(lldb) " prompt in with program output by always manually checking for program output. This was done by having the command interpreter know when it is in the middle of executing a command by setting a bool. This was needed since sometimes when a command would run the target, like with a command like 'expression (int)printf("hello\n")', the process would push a new input reader, and then pop it when it was done. This popping of the input reader would cause the command interpreter to get sent a reactivated message (from the private process state thread) and cause it to ask for another command, even though we were still in the middle of the command ('expression (int)printf("hello\n")'). Now we set a bool to true, run the command and set the bool to false. If we get reactivated while we are in the middle of a command, we don't say we are ready for a new command. This coupled with emitting the STDOUT/STDERR first after each command, followed by the command results, followed by then saying we are ready for a new command, should help cleanup the command line output on all platforms.

Then make the Thread a Broadcaster, and get it to broadcast when the selected frame is changed (but only from the Command Line) and when Thread::ReturnFromFrame
changes the stack.
Made the Driver use this notification to print the new thread status rather than doing it in the command.
Fixed a few places where people were setting their broadcaster class by hand rather than using the static broadcaster class call.

Add an lldb command line option to specify a core file: --core/-c.
For consistency, change the "target create" command to also use --core.

Added the ability to override command line commands. In some cases GUI interfaces
might want to intercept commands like "quit" or "process launch" (which might cause
the process to re-run). They can now do so by overriding/intercepting commands
by using functions added to SBCommandInterpreter using a callback function. If the
callback function returns true, the command is assumed to be handled. If false
is returned the command should be evaluated normally.
Adopted this up in the Driver.cpp for intercepting the "quit" command.

command line driver, including the lldb prompt being output by
editline, the asynchronous process output & error messages, and
asynchronous messages written by target stop-hooks.
As part of this it introduces a new Stream class,
StreamAsynchronousIO. A StreamAsynchronousIO object is created with a
broadcaster, who will eventually broadcast the stream's data for a
listener to handle, and an event type indicating what type of event
the broadcaster will broadcast. When the Write method is called on a
StreamAsynchronousIO object, the data is appended to an internal
string. When the Flush method is called on a StreamAsynchronousIO
object, it broadcasts it's data string and clears the string.
Anything in lldb-core that needs to generate asynchronous output for
the end-user should use the StreamAsynchronousIO objects.
I have also added a new notification type for InputReaders, to let
them know that a asynchronous output has been written. This is to
allow the input readers to, for example, refresh their prompts and
lines, if desired. I added the case statements to all the input
readers to catch this notification, but I haven't added any code for
handling them yet (except to the IOChannel input reader).

public types and public enums. This was done to keep the SWIG stuff from
parsing all sorts of enums and types that weren't needed, and allows us to
abstract our API better.

used as the arguments for the inferior program. So for example you can do
% lldb /bin/ls /tmp ~/Documents
And "lldb" will use "/bin/ls" as the program and send arguments "/tmp" and
"~/Documents" as the launch args.
If you specify a file, then all remaining args after option parsing
will be used for program arguments:
% lldb -f /bin/ls /tmp ~/Documents
If you need to pass option values to your inferior program, just terminate
the "lldb" command line driver options with "--":
% lldb -- /bin/ls -AFl /tmp
The arguments are placed into the "settings" variable named
"target.process.run-args". This allows you to just run the program using
"process launch" and, if no args are specified on that command, the
"target.process.run-args" values will be used:
% lldb -- /bin/ls -AFl /tmp
Current executable set to '/bin/ls' (x86_64).
(lldb) settings show target.process.run-args
target.process.run-args (array):
[0]: '-AFl'
[1]: '/tmp'
(lldb)
(lldb) r
Process 56753 launched: '/bin/ls' (x86_64)

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.

The top of the header file seems to indicate that this was
intended to be over at include/lldb/Core but we should be in line
with the .cpp file's location so it's include/lldb/Utility for now.
