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.

+ * BeOS dynamic loading support
+ *
+ * This uses shared libraries, but BeOS has its own way of doing things
+ * (much easier than dlfnc.h, from the look of things).  We'll use a
+ * Python Dictionary object to store the images_ids so we can be very
+ * nice and unload them when we exit.
+ *
+ * Note that this is thread-safe.  Probably irrelevent, because of losing
+ * systems... Python probably disables threads while loading modules.
+ * Note the use of "probably"!  Better to be safe than sorry. [chrish]
+ *
+ * As of 1.5.1 this should also work properly when you've configured
+ * Python without thread support; the 1.5 version required it, which wasn't
+ * very friendly.  Note that I haven't tested it without threading... why
+ * would you want to avoid threads on BeOS? [chrish]
+ *
+ * As of 1.5.2, the PyImport_BeImageID() function has been removed; Donn
+ * tells me it's not necessary anymore because of PyCObject_Import().
+ * [chrish]
