Caroline Tice 2d5289d621 Various fixes mostly relating to the User Settings stuff:
- Added new utility function to Arg, GetQuotedCommandString, which re-assembles
the args into a string, replacing quotes that were originally there.

- Modified user settings stuff to always show individual elements when printing out
arrays and dictionaries.

- Added more extensive help to 'settings set', explaining more about dictionaries
and arrays (including current dictionary syntax).

- Fixed bug in user settings  where quotes were being stripped and lost, so that
sometimes array or dictionary elements that ought to have been a single element
were being split up.

Caroline Tice 405fe67f14 Modify existing commands with arguments to use the new argument mechanism
(for standardized argument names, argument help, etc.)

Caroline Tice deaab2220e Modify command options to use the new arguments mechanism. Now all command option
arguments are specified in a standardized way, will have a standardized name, and
have functioning help.

The next step is to start writing useful help for all the argument types.

Caroline Tice 1559a46b3e Create more useful instance names for target, process and thread instances.
Change default 'set' behavior so that all instance settings for the specified variable will be
updated, unless the "-n" ("--no_override") command options is specified.

Caroline Tice daccaa9e83 Add UserSettings to Target class, making Target settings
the parent of Process settings;   add 'default-arch' as a
class-wide setting for Target.    Replace            lldb::GetDefaultArchitecture
with Target::GetDefaultArchitecture & Target::SetDefaultArchitecture.

Add 'use-external-editor' as user setting to Debugger class & update
code appropriately.

Add Error parameter to methods that get user settings, for easier
reporting of bad requests.

Fix various other minor related bugs.

Fix test cases to work with new changes.

Greg Clayton ed8a705cea General command line help cleanup:
- All single character options will now be printed together
- Changed all options that contains underscores to contain '-' instead
- Made the help come out a little flatter by showing the long and short
  option on the same line.
- Modified the short character for "--ignore-count" options to "-i"

Greg Clayton a701509229 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").

Caroline Tice 7d9edf670b Modify "settings list" so you can specify a particular instance setting name,
or a settings prefix, and it will list information about the subset of settings
you requested.  Also added tab-completion (now that it takes an optional argument).

Caroline Tice 101c7c2060 Make all debugger-level user settable variables into instance variables.
Make get/set variable at the debugger level always set the particular debugger's instance variables rather than
the default variables.

Caroline Tice 3df9a8dfd7 This is a very large commit that completely re-does the way lldb
handles user settable internal variables (the equivalent of set/show
variables in gdb).  In addition to the basic infrastructure (most of
which is defined in UserSettingsController.{h,cpp}, there are examples
of two classes that have been set up to contain user settable
variables (the Debugger and Process classes).  The 'settings' command
has been modified to be a command-subcommand structure, and the 'set',
'show' and 'append' commands have been moved into this sub-commabnd
structure.  The old StateVariable class has been completely replaced
by this, and the state variable dictionary has been removed from the
Command Interpreter.  Places that formerly accessed the state variable
mechanism have been modified to access the variables in this new
structure instead (checking the term-width; getting/checking the
prompt; etc.)

Variables are attached to classes; there are two basic "flavors" of
variables that can be set: "global" variables (static/class-wide), and
"instance" variables (one per instance of the class).  The whole thing
has been set up so that any global or instance variable can be set at
any time (e.g. on start up, in your .lldbinit file), whether or not
any instances actually exist (there's a whole pending and default
values mechanism to help deal with that).

Greg Clayton 6611103cfe 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.
