Now that there is also support for python3, there is no need to specify
python2 explicitly.

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

Add a context menu (right-click) that provides options for copying to
clipboard, including, for trees, the ability to copy only the cell under
the mouse pointer.

Committer testing:

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

  Simply right click and pick "Copy selection", that at this point has
  just the first line, not expanded, then see what was copied by pressing
  shift+control+v on a terminal:

Call Path,Object,Count,Time (ns),Time (%),Branch Count,Branch Count (%)
▶ simple-retpolin,,,,,,

  Ditto after expanding, i.e. the selection continues to be just one
  line:

Call Path           Object   Count   Time (ns)   Time (%)   Branch Count   Branch Count (%)
▼ simple-retpolin

   Now select all the lines with the mouse and control+shift+v again:

Call Path                     Object             Count   Time (ns)   Time (%)   Branch Count   Branch Count (%)

Add support for copying to clipboard. Two menu options are added to copy the
selected rows / columns with normal spacing, or as comma-separated-values.

No more tracebacks, but the fonts don't get enlarged, which is kinda

Support both Python2 and Python3 in the syscall-counts-by-pid.py script

There may be differences in the ordering of output lines due to
differences in dictionary ordering etc.  However the format within lines
should be unchanged.

The use of 'from __future__' implies the minimum supported Python2 version
is now v2.6

If no selection is made on the 'Selected branches' dialog, then the
output is the same as the 'All branches' report. That is not really an
error, and is not desirable for future reports, so remove it.

Create new dialog data item classes to replace SQLTableDialogDataItem.
This separates out different dialog data items and makes it easier to
add new ones. SQLTableDialogDataItem is removed in a separate patch
because it makes the diff more readable.
