Also renamed the Compare function to IsEqualTo, to

For iOS native lldb, don't initialize the ModuleList notifier
callback. See the added comment for details on how this is a problem
in that environment. We'll need to restructure how the ModuleDidLoad
notification is called vrs. when the DynamicLoader pluging has had
a chance to set the Sectino load addresses.

Added a "step-in-target" flag to "thread step-in" so if you have something like:
Process 28464 stopped
* thread #1: tid = 0x1c03, function: main , stop reason = breakpoint 1.1
frame #0: 0x0000000100000e08 a.out`main at main.c:62
61
-> 62 int A6 = complex (a(4), b(5), c(6)); // Stop here to step targetting b and hitting breakpoint.
63
and you want to get into "complex" skipping a, b and c, you can do:
(lldb) step -t complex
Process 28464 stopped
* thread #1: tid = 0x1c03, function: complex , stop reason = step in
frame #0: 0x0000000100000d0d a.out`complex at main.c:44
41
42 int complex (int first, int second, int third)
43 {
-> 44 return first + second + third; // Step in targetting complex should stop here
45 }

47 int main (int argc, char const *argv[])

Fixed zero sized arrays to work correctly. This will only happen once we get a clang that emits correct debug info for zero sized arrays. For now I have marked the TestStructTypes.py as an expected failure.

- add new header lldb-python.h to be included before other system headers
- short term fix (eventually python dependencies must be cleaned up)

Cleaned up the option parsing code to always pass around the short options as integers. Previously we cast this down to "char" and lost some information. I recently added an assert that would detect duplicate short character options which was firing during the test suite.
This fix does the following:
- make sure all short options are treated as "int"
- make sure that short options can be non-printable values when a short option is not required or when an option group is mixed into many commands and a short option is not desired
- fix the help printing to "do the right thing" in all cases. Previously if there were duplicate short character options, it would just not emit help for the duplicates
- fix option parsing when there are duplicates to parse options correctly. Previously the option parsing, when done for an OptionGroup, would just start parsing options incorrectly by omitting table entries and it would end up setting the wrong option value

Emit an error when using "target modules add PATH" where PATH points to a debug info only (dSYM) file.
Also added a "--uuid" option for "target modules add --uuid UUID" to locate and load a module by UUID if the host supports it.

Prevent async and sync calls to get profile data from stomping on each other.
At the same time, don't use '$' as end delimiter per chunk of profile data.

Make stack frames fix up their line table entries when the target has source remappings. Also rearranged how the m_sc.target_sp was filled in so it can be used during the StackFrame::GetSymbolContext(...) function.

This commit does three things:
(a) introduces a new notification model for adding/removing/changing modules to a ModuleList, and applies it to the Target's ModuleList, so that we make sure to always trigger the right set of actions
whenever modules come and go in a target. Certain spots in the code still need to "manually" notify the Target for several reasons, so this is a work in progress
(b) adds a new capability to the Platforms: locating a scripting resources associated to a module. A scripting resource is a Python file that can load commands, formatters, ... and any other action
of interest corresponding to the loading of a module. At the moment, this is only implemented on Mac OS X and only for files inside .dSYM bundles - the next step is going to be letting
the frameworks themselves hold their scripting resources. Implementors of platforms for other systems are free to implement "the right thing" for their own worlds
(c) hooking up items (a) and (b) so that targets auto-load the scripting resources as the corresponding modules get loaded in a target. This has a few caveats at the moment:
- the user needs to manually add the .py file to the dSYM (soon, it will also work in the framework itself)
- if two modules with the same name show up during the lifetime of an LLDB session, the second one won't be able to load its scripting resource, but will otherwise work just fine

the runtime if we have complete debug information
for a class.
Also made the Objective-C language runtime return
NULL when asked for the complete debug information
(i.e., information from DWARF, not information from
the runtime) if that information isn't present. It
used to return a non-authoritative version, which
made it hard for clients to determine whether
complete debug information was available.

I tracked down a leak that could happen when detaching from a process where the lldb_private::Process objects would stay around forever. This was caused by a eStateDetached event that was queued up on the lldb_private::Process private state thread listener. Since process events contain shared pointers to the process, this is dangerous if they don't get consume or cleared as having the lldb_private::Process class contain a collection of things that have a shared pointer to yourself is obviously bad.
To fix this I modified the Process::Finalize() function to clear this list. The actual thing that was holding onto the ModuleSP and thus the static archive, was a stack frame. Since the process wasn't going away, it still had thread objects and they still had frames. I modified the Thread::Destroy() to clear the stack frames to ensure this further doesn't happen.

There was a generic catch-all type for path arguments
called "eArgTypePath," and a specialized version
called "eArgTypeFilename." It turns out all the
cases where we used eArgTypePath we could have
used Filename or we explicitly meant a directory.
I changed Path to DirectoryName, made it use the
directory completer, and rationalized the uses of
Path.

options:
- added help ("help language") listing the
possible options;
- added the possibility of synonyms for language
names, in this case "ObjC" for "Objective-C";
and
- made matching against language names case
insensitive.
This should improve discoverability.

dynamic-loader
macosx-kernel

To settings can be set using:
(lldb) settings set plugin.dynamic-loader.macosx-kernel.disable-kext-loading true
I currently only hooked up the DynamicLoader plug-ins, but the code is very easy to duplicate when and if we need settings for other plug-ins.

Added a new setting that allows a python OS plug-in to detect threads and provide registers for memory threads. To enable this you set the setting:
settings set target.process.python-os-plugin-path lldb/examples/python/operating_system.py
Then run your program and see the extra threads.

More fixes to how we handle paths that are used to create a target.
This modification centralizes the location where and how what the user specifies gets resolved. Prior to this fix, the TargetList::CreateTarget variants took a FileSpec object which meant everyone had the opportunity to resolve the path their own way. Now both CreateTarget variants take a "const char *use_exe_path" which allows the TargetList::CreateTarget to centralize where the resolving happens and "do the right thing".

LLDB changes argv[0] when debugging a symlink. Now we have the notion of argv0 in the target settings:
target.arg0 (string) =
There is also the program argument that are separate from the first argument that have existed for a while:
target.run-args (arguments) =
When running "target create <exe>", we will place the untouched "<exe>" into target.arg0 to ensure when we run, we run with what the user typed. This has been added to the ProcessLaunchInfo and all other needed places so we always carry around the:
- resolved executable path
- argv0
- program args
Some systems may not support separating argv0 from the resolved executable path and the ProcessLaunchInfo needs to carry all of this information along so that each platform can make that decision.
