Subject: [PATCH] tools/xen-foreign: Update python scripts to be Py3 compatible
The issues are:
* dict.has_key() was completely removed in Py3
* dict.keys() is an iterable rather than list in Py3, so .sort() doesn't work.
* list.sort(cmp=) was deprecated in Py2.4 and removed in Py3.
The has_key() issue is trivially fixed by switching to using the in keyword.
The sorting issue could be trivially fixed, but take the opportunity to
improve the code.
The reason for the sorting is to ensure that "unsigned long" gets replaced
before "long", and the only reason sorting is necessary is because
inttypes[arch] is needlessly a dictionary. Update inttypes[arch] to be a list
of tuples rather than a dictionary, and process them in list order.

Subject: [PATCH 6/8] pygrub: make python scripts work with 2.6 and up
Run 2to3 and pick the sensible suggestions.
Import print_function and absolute_import so 2.6 can work.
There has never been a curses.wrapper module according to 2.x and 3.x
doc, only a function, so "import curses.wrapper" is not correct. It
happened to work because 2.x implemented a (undocumented) module.
We only need to import curses to make curses.wrapper available to
pygrub.

From: Wei Liu <wei.liu2@citrix.com>
Date: Tue, 5 Mar 2019 14:13:17 +0000
Subject: [PATCH 7/8] pygrub/fsimage: make it work with python 3
With the help of two porting guides and cpython source code:
1. Use PyBytes to replace PyString counterparts.
2. Use PyVarObject_HEAD_INIT.
3. Remove usage of Py_FindMethod.
4. Use new module initialisation routine.
For #3, Py_FindMethod was removed, yet an alternative wasn't
documented. The code is the result of reverse-engineering cpython
commit 6116d4a1d1

Subject: [PATCH 2/4] pygrub/grub: always use integer for default entry
The original code set the default to either a string or an integer
(0) and relies on a Python 2 specific behaviour to work (integer is
allowed to be compared to string in Python 2 but not 3).
Always use integer. The caller (pygrub) already has code to handle
that.
