This fixes a regression introduced in bpo-38960.
When DFLAGS was empty, "$DFLAGS" results in an empty argument ("").
Without the quotes, an empty variable will be ignored by the shell.
I have noticed that `'` quotes are used everywhere except this particular case,
which was introduced in https://github.com/python/cpython/pull/18726
So, this is a trivial fix to enforce better consistency.
The ensurepip module now invokes pip via the runpy module.
Hence it is no longer tightly coupled with the internal API of the bundled
pip version, allowing easier updates to a newer pip version both
internally and for distributors.
This way, any changes to the internal pip API won't mean ensurepip needs to be
changed as well. Also, distributors can update their pip wheels independent on
CPython release schedule.

I've used this recipe a couple times and the filename editing has always
been less than useful and something I've removed. This is because many
modules end up losing which package they are located in, e.g. `util/date.py`.
* Remove the slice type.
* Make Slice a kind of the expr type instead of the slice type.
* Replace ExtSlice(slices) with Tuple(slices, Load()).
* Replace Index(value) with a value itself.
All non-terminal nodes in AST for expressions are now of the expr type.
Add --with-platlibdir option to the configure script: name of the
platform-specific library directory, stored in the new sys.platlitdir
attribute. It is used to build the path of platform-specific dynamic
libraries and the path of the standard library.
It is equal to "lib" on most platforms. On Fedora and SuSE, it is
equal to "lib64" on 64-bit systems.

PyGILState_Ensure() doesn't call PyEval_InitThreads() anymore when a
new Python thread state is created. The GIL is created by
Py_Initialize() since Python 3.7, it's not needed to call
PyEval_InitThreads() explicitly.
Add an assertion to ensure that the GIL is already created.
Add _bootsubprocess module to bootstrap Python: subprocess
implementation which only uses the os module.
On AIX, distutils.util uses _aix_support which calls
subprocess.check_output(), before the _posixsubprocess module is
built. Implement check_output() with os.system() in _bootsubprocess.
Clear the frames of daemon threads earlier during the Python shutdown to
call objects destructors. So "unclosed file" resource warnings are now
emitted for daemon threads in a more reliable way.
Cleanup _PyThreadState_DeleteExcept() code: rename "garbage" to
"list".
* Remove ceval parameter of take_gil(): get it from tstate.
* Move exit_thread_if_finalizing() call inside take_gil(). Replace
exit_thread_if_finalizing() with tstate_must_exit(): the caller is
now responsible to call PyThread_exit_thread().
* Move is_tstate_valid() assertion inside take_gil(). Remove
is_tstate_valid(): inline code into take_gil().
* Move gil_created() assertion inside take_gil().
python-gdb.py now checks for "take_gil" function name to check if a
frame tries to acquire the GIL, instead of checking for
"pthread_cond_timedwait" which is specific to Linux and can be a
different condition than the GIL.
It appears standard that moving the text insert cursor away from a selection clears the
selection. Clearing prevents accidental deletion of a possibly off-screen bit of text.
The update is for Ln and Col on the status bar.
* exit_thread_if_finalizing() does now access directly _PyRuntime
variable, rather than using tstate->interp->runtime since tstate
can be a dangling pointer after Py_Finalize() has been called.
* exit_thread_if_finalizing() is now called *before* calling
take_gil(). _PyRuntime.finalizing is an atomic variable,
we don't need to hold the GIL to access it.
* Add ensure_tstate_not_null() function to check that tstate is not
NULL at runtime. Check tstate earlier. take_gil() does not longer
check if tstate is NULL.
Cleanup:
* PyEval_RestoreThread() no longer saves/restores errno: it's already
done inside take_gil().
* PyEval_AcquireLock(), PyEval_AcquireThread(),
PyEval_RestoreThread() and _PyEval_EvalFrameDefault() now check if
tstate is valid with the new is_tstate_valid() function which uses
_PyMem_IsPtrFreed().
