test all aborts in the code which are caused by bad input parameters

[edwardhartnett]

We have a lot of cases where passing a bad parameter to a subroutine will call a bort(). These all need to be tested.

We are doing this testing with program test_bort.F90 and test script run_test_bort.sh.

Great progress here, only a few borts remain untested...
