[PATCH 37/41] perf scripts python: exported-sql-viewer.py: Add support for pyside2

From: Adrian Hunter <adrian.hunter@intel.com>

pyside2 is the future for pyside support.

Note pyside use Qt4 whereas pyside2 uses Qt5.

Committer testing:

On a system with just:

# rpm -qa| grep -i pyside
python2-pyside-1.2.4-7.fc29.x86_64
#

Running:

$ python ~acme/libexec/perf-core/scripts/python/exported-sql-viewer.py ~/c/adrian.hunter/simple-retpoline.db &
[1] 7438

Makes it use the pyside 1 files:

$ grep -i pyside /proc/7438/maps | cut -d ' ' -f 6- | sort -u
/usr/lib64/libpyside-python2.7.so.1.2.4
/usr/lib64/python2.7/site-packages/PySide/QtCore.so
/usr/lib64/python2.7/site-packages/PySide/QtGui.so
/usr/lib64/python2.7/site-packages/PySide/QtSql.so
$ rpm -qf /usr/lib64/libpyside-python2.7.so.1.2.4
python2-pyside-1.2.4-7.fc29.x86_64
$

To get PySide2 I guess one needs to do:

$ pip install PySide2

But thats a 142MiB download I can't do right now, perhaps before pushing
upstream...
