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. Signed-off-by: daryl.mcdaniel@intel.com git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@13197 6f19259b-4bc3-4df7-8a09-765794883524

"""distutils.spawn
|

|

Provides the 'spawn()' function, a front-end to various platform-
|
||||
specific functions for launching another program in a sub-process.
|
||||
Also provides the 'find_executable()' to search the path for a given
|
||||
executable name.
