Unify the comparison idioms use.
Always use `if(!strcmp())` for "if string equals"
and `if(strcmp())` for "if string is not equal".
Never use `== 0` and `!= 0` with `strcmp()`.
Minor reformatting of the code immediately surrounding the
refactored lines.

Clean up use of strcmp/strncmp/strncasecmp for command line arguments.
Never use anything but `strcmp()` unless absolutely neccessary.
Partialy resolvesipmitool/ipmitool#104
Cleanup all unused-parameter warnings. Each warning was examined to
verify it wasn't simply a case of a build macro difference.

Remove all direct comparisons to 'NULL' for pointers.
Replace them with boolean-like 'if (ptr)' and 'if (!ptr)'.
This makes conditions shorter and easier to read.
