Function parseOpt

testlib.h:5355–5385

* Parse the opt at a given index, and put it into the opts maps. * * An opt can has the following form: * 1) -keyName=value or --keyName=value (ex. -n=10 --test-count=20) * 2) -keyName value or --keyName value (ex. -n 10 --test-count 20) * 3) -kNumval or --kNumval (ex. -n10 --t20) * 4) -boolProperty or --boolProperty (ex. -sorted --tree-only) * * Only the s

 * TODO. Please refer to the implementation to see how the code handles the 3rd and 4th forms separately.
