Subject[PATCH 18/73] perf scripts python: exported-sql-viewer.py: Add 'About' dialog box
Date
From: Adrian Hunter <adrian.hunter@intel.com>

With support for Python 2 or 3 and PySide 1 or 2 (Qt 4 or 5), it is
useful to see what versions are in use. Add an 'About' dialog box that
displays Python, PySide, Qt and database server (SQLite or PostgreSQL)
version numbers.

Committer testing:

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

Then go to 'Help', then 'About', select all the lines with the mouse
press 'Control+C', then, on the same terminal press control+shift+V
which shows my current environment:

Python version: 2.7.16
PySide version: 1
Qt version: 4.8.7
SQLite version: 3.26.0
