I added Makefile rules for running MIDAS through the clang-tidy static code 
analyzer. (rules for running cppcheck have gone missing, I hope I find them).

Reports from clang-tidy are somewhat repetitive (complain about the same class of 
non-problem problems repeatedly), but several warnings and errors identified real 
bugs.

Specifically, detection of memory leaks in error paths and detection of NULL 
pointer dereference and use of uninitialized variables is pretty solid.

Fixes for the worst problems reported by cppcheck and clang-tidy are already 
committed to midas git.

K.O.
