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.

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").

Greg Clayton 6dbd39838d Fixed a missing newline when dumping mixed disassembly.
Added a "bool show_fullpaths" to many more objects that were
previously always dumping full paths.

Fixed a few places where the DWARF was not indexed when we
we needed it to be when making queries. Also fixed an issue
where the DWARF in .o files wasn't searching all .o files
for the types.

Fixed an issue with the output from "image lookup --type <TYPENAME>"
where the name and byte size might not be resolved and might not
display. We now call the accessors so we end up seeing all of the
type info.

Caroline Tice 3f4c09c1c3 Small help text fixes, to make it more consistent and accurate.
Temporarily remove -l option from 'expr' command (at Sean's request).

Jim Ingham 2976d00adb Change "Current" as in GetCurrentThread, GetCurrentStackFrame, etc, to "Selected" i.e. GetSelectedThread. Selected makes more sense, since these are set by some user action (a selection). I didn't change "CurrentProcess" since this is always controlled by the target, and a given target can only have one process, so it really can't be selected.

Greg Clayton 9da7bd0739 Got a lot of the kinks worked out in the inline support after debugging more
complex inlined examples.

StackFrame classes don't have a "GetPC" anymore, they have "GetFrameCodeAddress()".
This is because inlined frames will have a PC value that is the same as the 
concrete frame that owns the inlined frame, yet the code locations for the
frame can be different. We also need to be able to get the real PC value for
a given frame so that variables evaluate correctly. To get the actual PC
value for a frame you can use:

    addr_t pc = frame->GetRegisterContext()->GetPC();

Some issues with the StackFrame stomping on its own symbol context were 
resolved which were causing the information to change for a frame when the
stack ID was calculated. Also the StackFrame will now correctly store the
symbol context resolve flags for any extra bits of information that were 
looked up (if you ask for a block only and you find one, you will alwasy have
the compile unit and function).

Greg Clayton dda4f7b520 Centralized all disassembly into static functions in source/Core/Disassembler.cpp.
Added the ability to read memory from the target's object files when we aren't
running, so disassembling works before you run!

Cleaned up the API to lldb_private::Target::ReadMemory().

Cleaned up the API to the Disassembler to use actual "lldb_private::Address"
objects instead of just an "addr_t". This is nice because the Address objects
when resolved carry along their section and module which can get us the 
object file. This allows Target::ReadMemory to be used when we are not 
running.

Added a new lldb_private::Address dump style: DumpStyleDetailedSymbolContext
This will show a full breakdown of what an address points to. To see some
sample output, execute a "image lookup --address <addr>".

Fixed SymbolContext::DumpStopContext(...) to not require a live process in
order to be able to print function and symbol offsets.

Greg Clayton 0c5cd90d63 Added function name types to allow us to set breakpoints by name more
intelligently. The four name types we currently have are:

eFunctionNameTypeFull       = (1 << 1), // The function name.
                                        // For C this is the same as just the name of the function
                                        // For C++ this is the demangled version of the mangled name.
                                        // For ObjC this is the full function signature with the + or
                                        // - and the square brackets and the class and selector
eFunctionNameTypeBase       = (1 << 2), // The function name only, no namespaces or arguments and no class 
                                        // methods or selectors will be searched.
eFunctionNameTypeMethod     = (1 << 3), // Find function by method name (C++) with no namespace or arguments
eFunctionNameTypeSelector   = (1 << 4)  // Find function by selector name (ObjC) names


this allows much more flexibility when setting breakoints:

(lldb) breakpoint set --name main --basename
(lldb) breakpoint set --name main --fullname
(lldb) breakpoint set --name main --method
(lldb) breakpoint set --name main --selector

The default:

(lldb) breakpoint set --name main

will inspect the name "main" and look for any parens, or if the name starts
with "-[" or "+[" and if any are found then a full name search will happen.
Else a basename search will be the default.

Fixed some command option structures so not all options are required when they
shouldn't be.

Cleaned up the breakpoint output summary.

Made the "image lookup --address <addr>" output much more verbose so it shows
all the important symbol context results. Added a GetDescription method to 
many of the SymbolContext objects for the more verbose output.

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.

Jim Ingham 8651121c11 Change the Options parser over to use a mask rather than an ordinal for option sets.
Fixed the Disassemble arguments so you can't specify start address or name in multiple ways.
Fixed the command line input so you can specify the filename without "-f" even if you use other options.
