Add exit() as program terminator; remove chpl_error(), chpl_internal_error().
Add exit() as program terminator; remove chpl_error(), chpl_internal_error().

I had thought Coverity would assume that exit() in C code would halt the
program, but indications are that it does not.  If it did, then Coverity
would see that chpl_error() and chpl_internal_error() both caused
program termination, because both call chpl_exit_any(), which calls
chpl_exit_common(), which calls exit().  Coverity did not seem to be
picking this up, and it also failed to respond to the modelling file
telling it that chpl_error() and chpl_internal_error() caused a halt.
I've found an indication on the web that Coverity does not by default
assume that exit() cause a halt, so here I'm saying so explicitly.
