[PATCH 00/20] CodeSonar Clean Up Patches

[Joel Sherrill]

Hi

Josh O'guin and I have been using CodeSonar to evaluate RTEMS.
This is a first set of patches which clears up some of the reported
issues.  

Most of the patches are small. However, the tools/ directory
is a single patch for all files. They are not compiled with 
warnings and ignored by Coverity Scan. This means that they
have never been examined with any rigor and there were a lot
of issues to address.

Hopefully none of these will be too controversial.
