patches: Fix ctypes import error
This change adds a patch that allows ctypes to be imported by ignoring
a failing PyDLL() call (which is not supported under Unikraft due to
lack of dynamic linking).

Makefile.uk: Fix generated header include path
Previously LIBPYTHON3_SRC was in the include path, leading to a wrong
pyconfig.h, if present, to be pulled into the Python build. Such a file
could remain after being generated by a rootfs build.
This change both removes LIBPYTHON3_SRC from the include path, as it
provides no needed headers, as well as ensures that the rootfs build
does not leave a pyconfig.h file in the origin directory.

Makefile.uk: Remove forceful setting of config
Previously the python Makefile would forcefully set the Kconfig value
`STACK_SIZE_PAGE_ORDER` to 10, a minimum value for python to work.

Makefile.uk: Allow configuring with custom config file
The `.config.orig` rule does a backup of the config file before changing
it to set `CONFIG_STACK_SIZE_PAGE_ORDER=10`. This used a hardcoded path
to the default `.config` file instead of `$(C)`, which can be set to a
custom one.
Using a hardcoded path will fail if trying to build with a different
config file than the default one (i.e. using `make C=path-to-config`).
One of the usecases is `kraftkit`, which uses `.config.python3...`
instead of the default `.config` file.

Correct license headers introduced by University Politehnica of Bucharest
This commit removes the additional clause
"THIS HEADER MAY NOT BE EXTRACTED OR MODIFIED IN ANY WAY"
from BSD license headers that got introduced by mistake
with the following commits: 5772e54 - Add stubs.c for stubbed functions (Vlad-Andrei Badoiu) 2b241d4 - Add Makefile.uk (Vlad-Andrei Badoiu) ab18836 - Add init.c for initialization (Vlad-Andrei Badoiu)
On the one hand, this additional clause is redundant because
the BSD license already states that it must remain and the
copyright notice must be kept.
On the other hand, the clause freezes the file header
and prohibits future contributors from extending the
copyright notice for their contributions. This additional
clause is not part of the official BSD 3-clause.

the author's affiliation consents to the change with a

This file is copied from a './Modules/config.c' of a Linux build and it contains
the modules init functions and their registration as Python extensions. We
commented the registration of the modules that we do not support yet. They
should be enabled back when we will add support for them by porting the
underlying native libraries.
_sysconfigdata.py contains all the configuration data used by the interpreter at
runtime. This patch adds the slightly changed file generated by a ./configure
run.
pyconfig.h is generated when running ./configure and it contains the features
that are available on the build machine. This is copied from a local build.
In the original build, there are two kinds of sources: for core functionality
and for extensions. Each of them has a different set of compiler flags. In
order to emulate the same behavior, we define two libraries: 'python3-core' and
'python3-extensions'. Please notice that we still keep a 'python3' library as
the main logical library.
