Fixed an issues with the SBType and SBTypeMember classes:
- Fixed SBType to be able to dump itself from python
- Fixed SBType::GetNumberOfFields() to return the correct value for objective C interfaces
- Fixed SBTypeMember to be able to dump itself from python
- Fixed the SBTypeMember ability to get a field offset in bytes (the value
  being returned was wrong)
- Added the SBTypeMember ability to get a field offset in bits


Cleaned up a lot of the Stream usage in the SB API files.

Greg Clayton cac9c5f971 Added to the public API to allow symbolication:
- New SBSection objects that are object file sections which can be accessed
  through the SBModule classes. You can get the number of sections, get a 
  section at index, and find a section by name.
- SBSections can contain subsections (first find "__TEXT" on darwin, then
  us the resulting SBSection to find "__text" sub section).
- Set load addresses for a SBSection in the SBTarget interface
- Set the load addresses of all SBSection in a SBModule in the SBTarget interface
- Add a new module the an existing target in the SBTarget interface
- Get a SBSection from a SBAddress object

This should get us a lot closer to being able to symbolicate using LLDB through
the public API.

Greg Clayton a2eee184e0 Removed the function:
ModuleSP
	Module::GetSP();

Since we are now using intrusive ref counts, we can easily turn any
pointer to a module into a shared pointer just by assigning it.

Greg Clayton 7e9b1fd045 We were leaking a stack frame in StackFrameList in Thread.cpp which could
cause extra shared pointer references to one or more modules to be leaked.
This would cause many object files to stay around the life of LLDB, so after
a recompile and rexecution, we would keep adding more and more memory. After
fixing the leak, we found many cases where leaked stack frames were still
being used and causing crashes in the test suite. These are now all resolved.

Greg Clayton 00e6fbfee9 Make the SBAddress class easier to use when using the public
API. 

SBTarget changes include changing:

bool
SBTarget::ResolveLoadAddress (lldb::addr_t vm_addr, 
                              lldb::SBAddress& addr);

to be:

lldb::SBAddress
SBTarget::ResolveLoadAddress (lldb::addr_t vm_addr);

SBAddress can how contruct itself using a load address and a target 
which can be used to resolve the address:

SBAddress (lldb::addr_t load_addr, lldb::SBTarget &target);

This will actually just call the new SetLoadAddress accessor:

void
SetLoadAddress (lldb::addr_t load_addr, 
                lldb::SBTarget &target);

This function will always succeed in making a SBAddress object
that can be used in API calls (even if "target" isn't valid).
If "target" is valid and there are sections currently loaded,
then it will resolve the address to a section offset address if
it can. Else an address with a NULL section and an offset that is
the "load_addr" that was passed in. We do this because a load address
might be from the heap or stack.

Greg Clayton 05d2b7f741 Added some functions to our API related to classifying symbols as code, data,
const data, etc, and also for SBAddress objects to classify their type of
section they are in and also getting the module for a section offset address.

    lldb::SymbolType SBSymbol::GetType();
    
    lldb::SectionType SBAddress::GetSectionType ();
    lldb::SBModule SBAddress::GetModule ();

Greg Clayton 2d4edfbc6a Modified all logging calls to hand out shared pointers to make sure we
don't crash if we disable logging when some code already has a copy of the
logger. Prior to this fix, logs were handed out as pointers and if they were
held onto while a log got disabled, then it could cause a crash. Now all logs
are handed out as shared pointers so this problem shouldn't happen anymore.
We are also using our new shared pointers that put the shared pointer count
and the object into the same allocation for a tad better performance.

Greg Clayton cfd1aced7e Cleaned up the API logging a lot more to reduce redundant information and
keep the file size a bit smaller.

Exposed SBValue::GetExpressionPath() so SBValue users can get an expression
path for their values.

Caroline Tice 750cd1755d Clean up the API logging code:
- Try to reduce logging to one line per function call instead of tw
      - Put all arguments & their values into log for calls
      - Add 'this' parameter information to function call logging, making it show the appropriate
        internal pointer (this.obj, this.sp, this.ap...)
      - Clean up some return values
      - Remove logging of constructors that construct empty objects
      - Change '==>' to '=>'  for showing result values...
      - Fix various minor bugs
      - Add some protected 'get' functions to help getting the internal pointers for the 'this' arguments...

Caroline Tice ceb6b1393d First pass at adding logging capabilities for the API functions. At the moment
it logs the function calls, their arguments and the return values.  This is not
complete or polished, but I am committing it now, at the request of someone who
really wants to use it, even though it's not really done.  It currently does not
attempt to log all the functions, just the most important ones.  I will be 
making further adjustments to the API logging code over the next few days/weeks.
(Suggestions for improvements are welcome).


Update the Python build scripts to re-build the swig C++ file whenever 
the python-extensions.swig file is modified.

Correct the help for 'log enable' command (give it the correct number & type of
arguments).

Caroline Tice dac97f31a3 Remove all the __repr__ methods from the API/*.h files, and put them
into python-extensions.swig, which gets included into lldb.swig, and
adds them back into the classes when swig generates it's C++ file.  This
keeps the Python stuff out of the general API classes.

Also fixed a small bug in the copy constructor for SBSymbolContext.

Caroline Tice dde9cff32a Add GetDescription() and __repr__ () methods to most API classes, to allow
"print" from inside Python to print out the objects in a more useful
manner.

Greg Clayton f5e56de080 Moved the section load list up into the target so we can use the target
to symbolicate things without the need for a valid process subclass.

Greg Clayton 0996003126 Added some missing API for address resolving within a module, and looking
up a seciton offset address (SBAddress) within a module that returns a
symbol context (SBSymbolContext). Also added a SBSymbolContextList in 
preparation for adding find/lookup APIs that can return multiple results.

Added a lookup example code that shows how to do address lookups.

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.
