Re http://bugs.python.org/issue4315

The symbol table used the same name dictionaries to recursively
analyze each of its child blocks, even though the dictionaries are
modified during analysis.  The fix is to create new temporary
dictionaries via the analyze_child_block().  The only information that
needs to propagate back up is the names of the free variables.

Add more comments and break out a helper function.  This code doesn't
get any easier to understand when you only look at it once a year.

to ensure that the build will succeed in a clean
checkout and with a non-default deployment target.

explicit global variables.

sys.path on OSX, to make it easier to share (some) installed
packages between the system install and a user install.

should cause tests to be skipped.  Also rename import_function
to the more descriptive get_attribute and add a docstring.

though with some changes by me.  This patch should not be back ported or
forward ported.  It's a bit too risky for 2.6 and 3.x does things fairly
differently.

* Remove last traces of "MacPython"
* Add options to build different flavors of the installer
  (still defaulting to a 2-way universal build that
  runs on OSX 10.3)

in PythonLauncher, replacing them with the correct counterparts.

tests that expect to be skipped if imports fail or functions don't
exist to use import_function and import_module.  The ultimate goal is
to change regrtest to not skip automatically on ImportError.  Checking
in now to make sure the buldbots don't show any errors on platforms
I can't direct test on.

that needs to be installed on OSX (depending on the configure flags)

* Changes code for updating folder icons from Python code
  that uses the deprecated Carbon module to a much simpler
