Add test cases to test various aspect of the 'alias' command.

function and also hooked up better error reporting for when things fail.

Fixed issues with trying to display children of pointers when none are
supposed to be shown (no children for function pointers, and more like this).
This was causing child value objects to be made that were correctly firing
an assertion.

and add teardown hook to test_pass_host_env_vars() in order to properly
unset the host environment variables set while running the test case.

values or persistent expression variables. Now if an expression consists of
a value that is a child of a variable, or of a persistent variable only, we
will create a value object for it and make a ValueObjectConstResult from it to
freeze the value (for program variables only, not persistent variables) and
avoid running JITed code. For everything else we still parse up and JIT code
and run it in the inferior. 

There was also a lot of clean up in the expression code. I made the 
ClangExpressionVariables be stored in collections of shared pointers instead
of in collections of objects. This will help stop a lot of copy constructors on
these large objects and also cleans up the code considerably. The persistent
clang expression variables were moved over to the Target to ensure they persist
across process executions.

Added the ability for lldb_private::Target objects to evaluate expressions.
We want to evaluate expressions at the target level in case we aren't running
yet, or we have just completed running. We still want to be able to access the
persistent expression variables between runs, and also evaluate constant 
expressions. 

Added extra logging to the dynamic loader plug-in for MacOSX. ModuleList objects
can now dump their contents with the UUID, arch and full paths being logged with
appropriate prefix values.

Thread hardened the Communication class a bit by making the connection auto_ptr
member into a shared pointer member and then making a local copy of the shared
pointer in each method that uses it to make sure another thread can't nuke the
connection object while it is being used by another thread.

Added a new file to the lldb/test/load_unload test that causes the test a.out file
to link to the libd.dylib file all the time. This will allow us to test using
the DYLD_LIBRARY_PATH environment variable after moving libd.dylib somewhere else.

the lldb PyThon API SBSourceManager to display source files.

To accomodate this, the C++ SBSourceManager API has been changed to take an

Example:

    def test_evaluate_expression_python(self):
        """Test SBFrame.EvaluateExpression() API for evaluating an expression."""
    ...

The opposite of Python APIs only test is an lldb command line test, which sends
commands to the lldb command interpreter.  Add a '-a' option to the test driver
to skip Python API only tests.

Modify TestExprs.py to mark a test as @python_api_test and remove an @expectedFailure
decorator as the bug has been fixed.

way of iterating through an aggregate data structure.  The added example usage
is from an actual use in test/foundation/TestSymbolTable.py:

    2. Pass a container of aggregate which provides APIs to get to the size and
       the element of the aggregate:

    # Module is a container of symbol table 
    module = target.FindModule(filespec)
    for symbol in lldb_iter(module, 'GetNumSymbols', 'GetSymbolAtIndex'):
        name = symbol.GetName()

        self.runCmd('command alias print_hi expression printf ("\\n\\tHi!")')
        # This fails currently.
        self.runCmd('print_hi')

and modify existing test sequences to escape the escape character '\ to prevent it
from being interpreted by Python before passing on to the lldb command interpreter.

- Fix alias-building & resolving to properly handle optional arguments for command options.
- Add logging for command resolution ('log enable lldb commands')
- Fix alias resolution to properly handle commands that take raw input (resolve the alias, but
  don't muck up the raw arguments).

Net result:  Among other things, 'expr' command can now take strings with escaped characters and
not have the command handling & alias resolution code muck up the escaped characters. E.g.
 'expr printf ("\n\n\tHello there!")' should now work properly.


Not working yet:  Creating aliases with raw input for commands that take raw input.  Working on that.
e.g. 'command alias print_hi expr printf ("\n\tHi!")' does not work yet.
