Start putting together a more organized set of tests.
Remove the old ad-hoc test files.
Add a 'clean' target.
Make sure that variadic arguments take up a fullword.
Fix bugs found during testing:
1. %NBITS for negative values was returning incorrect values.
2. Declared names exceeding 31 (NAME_SIZE-1) characters were
   being silently truncated, and lookups were not, leading to
   unexpected behavior.
