Mostly clean ups but there are also a couple of out-of-bounds accesses
(including a potential write to the byte before a static buffer).
The main changes are:
* Fixes those out-of-bounds access (empty string to configure
test module could write the byte before a buffer, high cpu counts
could read outside of per-cpu structures).
* Improvements to string handling problems picked up by new compiler
warnings and other static checks. Most are fixing benign issues that
can't be tickled without code changes but still reduce the wtf factor
a little.
* Tidy up the terminal output.
