AppPkg/Applications/Python: Add Python 2.7.2 sources since the release of Python 2.7.3 made them unavailable from the python.org web site.
These files are a subset of the python-2.7.2.tgz distribution from python.org. Changed files from PyMod-2.7.2 have been copied into the corresponding directories of this tree, replacing the original files in the distribution.

+"""\
+List python source files.
+
+There are three functions to check whether a file is a Python source, listed
+here with increasing complexity:
+
+- has_python_ext() checks whether a file name ends in '.py[w]'.
+- look_like_python() checks whether the file is not binary and either has
+ the '.py[w]' extension or the first line contains the word 'python'.
+- can_be_compiled() checks whether the file can be compiled by compile().
+
+The file also must be of appropriate size - not bigger than a megabyte.
+
+walk_python_files() recursively lists all Python files under the given directories.
