shared pointers.

Changed the ExecutionContext over to use shared pointers for
the target, process, thread and frame since these objects can
easily go away at any time and any object that was holding onto
an ExecutionContext was running the risk of using a bad object.

Now that the shared pointers for target, process, thread and
frame are just a single pointer (they all use the instrusive
shared pointers) the execution context is much safer and still
the same size. 

Made the shared pointers in the the ExecutionContext class protected
and made accessors for all of the various ways to get at the pointers,
references, and shared pointers.

it to generate result variables that were not bound
to their underlying data.  This allowed the SBValue
class to use the interpreter (if possible).

Also made sure that any result variables that point
to stack allocations in the stack frame of the
interpreted expressions do not get live data.

The Module now adopts the ObjectFile's architecture after a valid architecture
has been loaded to make sure the module matches the object file.

Fix the RegularExpression class so it has a real copy constructor.
Fix the breakpoint setting with multiple shared libraries so it makes
  one breakpoint not one per shared library.
Add SBFileSpecList, to be used to expose the above to the SB interface (not done yet.)

    CommandObject::AddIDsArgumentData(CommandArgumentEntry &arg)

to be used from CommandObjectBreakpoint.cpp.  The helper function could also be useful
for commands in the future to manipulate watchpoints.

used to do this because we needed to find the shared pointer for a .o
file when the .o file's module was needed in a SymbolContext since the
module in a symbol context was a shared pointer. Now that we are using
intrusive pointers we don't have this limitation anymore since any
instrusive shared pointer can be made from a pointer to an object
all on its own.

Also switched over to having the Module and SymbolVendor use shared 
pointers to their object files as had a leak on MacOSX when the 
SymbolVendor's object file wasn't the same as the Module's (debug info
in a stand along file (dSYM file)). Now everything will correctly clean
itself up when the module goes away after an executable gets rebuilt.

Now we correctly get rid of .o files that are used with the DWARF with 
debug map executables on subsequent runs since the only shared pointer
to the object files in from the DWARF symbol file debug map parser, and
when the module gets replaced, it destroys to old one along with all .o 
files. 

Also added a small optimization when using BSD archives where we will
remove old BSD containers from the shared list when they are outdated.

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.

We had some cases where getting the shared pointer for a module from
the global module list was causing a performance issue when debugging
with DWARF in .o files. Now that the module uses intrusive ref counts,
we can easily convert any pointer to a shared pointer.

Also added a Debugger::Clear, which gets called in Debugger::Destroy to deal with all the targets in the Debugger.  Also made the Driver's main loop call Destroy on the debugger, rather than just Destroying the currently selected Target's process.
