ecbb0bb169 Fix more functions in Args to use StringRef.
This patch also marks the const char* versions as =delete to prevent
their use.  This has the potential to cause build breakages on some
platforms which I can't compile.  I have tested on Windows, Linux,
and OSX.  Best practices for fixing broken callsites are outlined in
Args.h in a comment above the deleted function declarations.

Eventually we can remove these =delete declarations, but for now they
are important to make sure that all implicit conversions from
const char * are manually audited to make sure that they do not invoke a
conversion from nullptr.

b9c1b51e45 *** This commit represents a complete reformatting of the LLDB source code
*** to conform to clang-format’s LLVM style.  This kind of mass change has
*** two obvious implications:

Firstly, merging this particular commit into a downstream fork may be a huge
effort.  Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit.  The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):

    find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
    find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;

The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.

Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit.  There are alternatives available that will attempt
to look through this change and find the appropriate prior commit.  YMMV.

7428a18c1e LLDB help content has accumulated over time without a recent attempt to
review it for consistency, accuracy, and clarity. These changes attempt to
address all of the above while keeping the text relatively terse.

308f73c5a3 Change the way command aliases are stored. Go from a model where a map holds the alias -> underlying command binding and another map holds the alias -> options, to a model where one single map holds the alias -> (all useful data) combination
Right now, obviously, this is just the pair of (CommandObjectSP,OptionArgVectorSP), so NFC

This is step one of a larger - and tricky - refactoring which will turn command aliases into interesting objects instead of passive storage that the command interpreter does smart things to
This refactoring, in turn, will allow us to do interesting things with aliases, such as intelligent and customizable help

1124045ac7 Don't #include "lldb-python.h" from anywhere.
Since interaction with the python interpreter is moving towards
being more isolated, we won't be able to include this header from
normal files anymore, all includes of it should be localized to
the python library which will live under source/bindings/API/Python
after a future patch.

None of the files that were including this header actually depended
on it anyway, so it was just a dead include in every single instance.

7d1069d09e If you try to auto-complete "target symbols<TAB>" you get "target symbolsadd" instead of "target symbols ".
Fix this by returning the fact that the "symbols" word is complete if there is nothing else to complete after the "symbols" word.

If you type help command <word> <word> <word> <missingSubCommand> (e.g. help script import or help type summary fake), you will get help on the deepest matched command word (i.e. script or type summary in the examples)
Also, reworked the logic for commands to produce their help to make it more object-oriented

The notion of Crossref command has long been forgotten, and there is nothing using CommandObjectCrossref in the current LLDB codebase
However, this was causing a conflict with process plugins and command aliases ending up in an infinite loop under situations such as:
(lldb) command alias monitor process plugin packet monitor
(lldb) process att -n Calendar
Process 28709 stopped
Executable module set to "/Applications/Calendar.app/Contents/MacOS/Calendar".
Architecture set to: x86_64-apple-macosx.
(lldb) command alias monitor process plugin packet monitor

This fixes the loop (and consequent crash) by disposing of Crossref commands and related code

c7bece56fa <rdar://problem/13069948>
Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary.

So I defined a new "lldb::offset_t" which should be used for all file offsets.

After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed.

Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections.

I added the ability for a process plug-in to implement custom commands. All the lldb_private::Process plug-in has to do is override:

virtual CommandObject *
GetPluginCommandObject();

This object returned should be a multi-word command that vends LLDB commands. There is a sample implementation in ProcessGDBRemote that is hollowed out. It is intended to be used for sending a custom packet, though the body of the command execute function has yet to be implemented!

5a98841673 Make raw & parsed commands subclasses of CommandObject rather than having the raw version implement an
Execute which was never going to get run and another ExecuteRawCommandString.  Took the knowledge of how
to prepare raw & parsed commands out of CommandInterpreter and put it in CommandObject where it belongs.

Also took all the cases where there were the subcommands of Multiword commands declared in the .h file for
the overall command and moved them into the .cpp file.

Made the CommandObject flags work for raw as well as parsed commands.

Made "expr" use the flags so that it requires you to be paused to run "expr".

85e8b81492 - Changed all the places where CommandObjectReturn was exporting a StreamString to just exporting
a Stream, and then added GetOutputData & GetErrorData to get the accumulated data.
- Added a StreamTee that will tee output to two provided lldb::StreamSP's.
- Made the CommandObjectReturn use this so you can Tee the results immediately to
the debuggers output file, as well as saving up the results to return when the command
is done executing.
- HandleCommands now uses this so that if you have a set of commands that continue the target
you will see the commands come out as they are processed.
- The Driver now uses this to output the command results as you go, which makes the interface
more reactive seeming.

e139cf2320 Add infrastructure for standardizing arguments for commands and
command options; makes it easier to ensure that the same type of
argument will have the same name everywhere, hooks up help for command
arguments, so that users can ask for help when they are confused about
what an argument should be; puts in the beginnings of the ability to
do tab-completion for certain types of arguments, allows automatic
syntax help generation for commands with arguments, and adds command
arguments into command options help correctly.

Currently only the breakpoint-id and breakpoint-id-range arguments, in
the breakpoint commands, have been hooked up to use the new mechanism.
The next steps will be to fix the command options arguments to use
this mechanism, and to fix the rest of the regular command arguments
to use this mechanism.  Most of the help text is currently missing or
dummy text; this will need to be filled in, and the existing argument
help text will need to be cleaned up a bit (it was thrown in quickly,
mostly for testing purposes).

Help command now works for all argument types, although the help may not
be very helpful yet.

Those commands that take "raw" command strings now indicate it in their
help text.

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").

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.
