Adds the lib directory to the mantid.pth file so importing mantid into vanilla python works
without setting up additional paths

The globally installed stip is not appropriate for MantidPlot. Ensures the
private copy is found first

Ensures our 3rdparty Python is picked up first so that
any warnings are suppressed by the /external warning

Framework code should not require Qt but the plots
module had become dependent on it by accident.

The internal sip module is installed inside PyQt
as is now standard. qtpy has not yet been updated
to expect this.

Reorganise RPM dependencies for slightly more clarity.

The version of python36-sip in EPEL produces a PyQt4 that segfaults
when an eventFilter is overridden in Python. So as to not introduce
any further custom rpms we build and package a private copy of PyQt4
for Python 3 builds on EL7
Refs #27631

EL7 uses python36- prefix for everything, Fedora just
uses python3- and Ubuntu still keeps everything in a
single bare sip directory.

Changes in matplotlib 2.2 require doubles for sizes
and setting the font manually avoids any issues if
fonts are not available on all platforms.

Fix issues with workbench plotting with matplotlib 3.1

It has been deprecated in matplotlib for a long time
and is removed in 3.0. Callers should clear the axes
themselves if thay is appropriate.

The API changed in matplotlib 3.1 but we still need to support
matplotlib > 1.5.

Some configurations now have the sip module inside
the PyQt package. To access the sip C API the
calling code must be aware of this.
All versions of Python that we support have capsule
support so the non-capule code paths have been removed

Python 2 does not have this DLL.

As far as I can tell these were leftover attributes from
a very old version of the matplotlib NavigationToolbarQT
class that have now been deprecated in matplotlib 3.1 and
set as readonly. A search back through matplotlib 1.5
suggests that they were not used and 1.5 is the minimum we
are required to support.

Users cannot do anything about this as they are not using
the methods directly. If they use them they will see
the warning but we do not want to see them if we are silently
accessing them.

Fine also on macOS. Nice feature!

Update macOS package script to account for Python 3 requirements

Cosmetic changes to directtools plot on Workbench

Remove the dead tool code DAEServ

Mainly this is due to more recent package versions on Python 3 to their
requirements are different.
