[edk2-libc Patch v3 2/5] AppPkg/Applications/Python: to remove document references to py2.7.2

["Jayaprakash, N" <n.jayaprakash@intel.com>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3589

This commit is to remove references to the py 2.7.2 UEFI port
in all documents from edk2-libc repo. This python interpreter
is no more supported on UEFI shell due to availability of
py 3.6.8 on UEFI.

-                                Version 2.7.2
-                                Release 1.02
-                                18 Jan. 2013
-
-
-1. OVERVIEW
-===========
-This document is devoted to general information on building and setup of the
-Python environment for UEFI 2.3, the invocation of the interpreter, and things
-that make working with Python easier.
-
-It is assumed that you already have either UDK2010 or a current snapshot of
-the EDK II sources from www.tianocore.org, and that you can successfully build
-packages within that distribution.
-
-2. Release Notes
-================
-  1)  All C extension modules must be statically linked (built in)
-  2)  The site and os modules must exist as discrete files in ...\lib\python.27
-  3)  User-specific configurations are not supported.
-  4)  Environment variables are not supported.
-
-3. Getting and Building Python
-======================================================
-  3.1 Getting Python
-  ==================
-  For development ease, a subset of the Python 2.7.2 distribution has been
-  included in the AppPkg source tree.  If a full distribution is desired, the
-  Python-2.7.2 directory can be removed or renamed and the full source code
-  downloaded from http://www.python.org/ftp/python/2.7.2/.
-
-  A.  Within your EDK II development tree, extract the Python distribution into
-    AppPkg/Applications/Python.  This should create the
-    AppPkg/Applications/Python/Python-2.7.2 directory.
-
-  B.  Copy the files from PyMod-2.7.2 into the corresponding directories within
-    the Python-2.7.2 tree.  This will overwrite existing files with files
-    modified for UEFI usage.
-
-  3.2 Building Python
-  ===================
-  A.  Edit Efi/config.c to enable the built-in modules you need.
-        Mandatory Built-in Modules:
-        edk2      errno       imp         marshal
-
-      Additional built-in modules which are required to use the help()
-      functionality provided by PyDoc, are:
-        _codecs     _collections    _functools    _random
-        _sre        _struct         _weakref      binascii
-        cStringIO   gc              itertools     math
-        operator    time
-
-  B.  Edit AppPkg/AppPkg.dsc to enable (uncomment) the PythonCore.inf line
-    within the [Components] section.
-
-  C.  Build AppPkg, which includes Python, using the standard "build" command:
-    For example, to build Python for an X64 CPU architecture:
-                    build -a X64 -p AppPkg\AppPkg.dsc
-
-4. Python-related paths and files
-=================================
-Python depends upon the existence of several directories and files on the
-target system.
-
-  \EFI                              Root of the UEFI system area.
-   |- \Tools                        Location of the Python.efi executable.
-   |- \Boot                         UEFI specified Boot directory.
-   |- \StdLib                       Root of the Standard Libraries sub-tree.
-       |- \etc                      Configuration files used by libraries.
-       |- \tmp                      Temporary files created by tmpfile(), etc.
-       |- \lib                      Root of the libraries tree.
-           |- \python.27            Directory containing the Python library
-               |                    modules.
-               |- \lib-dynload      Dynamically loadable Python extensions.
-               |- \site-packages    Site-specific packages and modules.
-
-
-5. Installing Python
-====================
-These directories, on the target system, are populated from the development
-system as follows:
-
-  * \Efi\Tools receives a copy of Build/AppPkg/DEBUG_VS2005/X64/Python.efi.
-                                               ^^^^^ ^^^^^^^^^^
-    Modify the host path to match the your build type and compiler.
-
-  * The \Efi\StdLib\etc directory is populated from the StdLib/Efi/StdLib/etc
-    source directory.
-
-  * Directory \Efi\StdLib\lib\python.27 is populated with packages and modules
-    from the AppPkg/Applications/Python/Python-2.7.2/Lib directory.
-    The recommended minimum set of modules (.py, .pyc, and/or .pyo):
-        os      stat      ntpath      warnings      traceback
-        site    types     copy_reg    linecache     genericpath
-
-  * Python C Extension Modules built as dynamically loadable extensions go into
-    the \Efi\StdLib\lib\python.27\lib-dynload directory.  This functionality is
-    not yet implemented.
-
-
-6. Example: Enabling socket support
-===================================
-  1.  enable {"_socket", init_socket}, in Efi\config.c
-  2.  enable Python-2.7.2/Modules/socketmodule.c in PythonCore.inf.
-  3.  copy socket.py over to /Efi/StdLib/lib/python.27 on your target system.
-  4.  Make sure dependent modules are present(.py) or built in(.c):
-        functools, types, os, sys, warnings, cStringIO, StringIO, errno
-
-  5.  build -a X64 -p AppPkg\AppPkg.dsc
-  6.  copy Build\AppPkg\DEBUG_VS2005\X64\Python.efi to \Efi\Tools on your
-      target system. Replace "DEBUG_VS2005\X64", in the source path, with
-      values appropriate for your tool chain and processor architecture.
-
-
-7. Running Python
-=================
-  Python must currently be run from an EFI FAT-32 partition, or volume, under
-  the UEFI Shell.  At the Shell prompt enter the desired volume name, followed
-  by a colon ':', then press Enter.  Python can then be executed by typing its
-  name, followed by any desired options and arguments.
-
-  EXAMPLE:
-      2.0 Shell> fs0:
-      2.0 FS0:\> python
-      Python 2.7.2 (default, Oct 13 2015, 16:21:53) [C] on uefi
-      Type "help", "copyright", "credits" or "license" for more information.
-      >>> exit()
-      2.0 FS0:\>
-
-  NOTE:
-      Python, as distributed, sends its interactive prompts to stderr.  If
-      STDERR isn't enabled in UEFI Setup so that it's output goes to the
-      console, it may appear that Python hangs on startup.  If this happens,
-      one may be able to rectify the condition by typing "exit()" followed
-      by <enter> to exit out of Python.  Then, type "exit" at the Shell prompt
-      which should enter Setup where you can use the Boot Maintenance
-      Manager to modify your Console settings.
-
-  NOTE:
-      Some platforms don't include the Setup utility, or don't allow STDERR to
-      be modified.  In these cases, Python may be started with the '-#' option
-      which will cause stderr to be the same as stdout and should allow
-      Python to be used interactively on those platforms.
-
-      Depending upon the version of Shell you are using, it may be necessary
-      to escape the '#' character so that the Shell doesn't interpret it as
-      the start of a comment.  The escape character is '^'.
-      Example:
-          python -^# -V
