. Fix formatting in kherr.c

. Fix formatting in kherr.c

2. The FormatMessage() call needs special handling for 64 bit
   platforms.  Add a compile time check for now until we figure out
   what to do.

3. Remove unused code from kherr.c.

4. Correct bad references to typedefs.  kherr_severity and
   kherr_suggestion were sometimes referenced as 'enum kherr_severity'
   and 'enum kherr_suggestion' even though they are typedefs.
