[bind10-dev] code coverage target changes and current coverage percentage

[Jeremy C. Reed]

I added a python code coverage make target. Now you can generate the 
python code coverage report using make. Use "./configure 
--with-pycoverage" to enable and use "make coverage" to do python (and 
c++) checks and generate code coverage reports. Or you may use the 
python specific "make report-python-coverage". The HTML is placed at 
coverage-python-html/ in your build tree. (Note we don't have separate 
way to run the tests for c++ versus python yet.)

You can see a new report at:

http://bind10.isc.org/~tester/2010/12/20101227201650-4024/coverage-python-html/
(generated by the make target)

and old report (for same source revision) at:
http://bind10.isc.org/~tester/2010/12/20101227201650-4024/python-coverage/
(generated via a standalone, rarely maintained, script)

I will soon disable that old script.

You can see the latest report with
http://bind10.isc.org/~tester/LATEST_PYTHON_UNITTEST_COVERAGE/

It is currently at 65%. The significant problems are:
