Use enumerations where practical to ease debugging

Browse Source 
We have a lot of enumerations; by declaring fields as such, we make it
easier when debugging, since the debugger can display the enumerations
in cleartext.  However, make sure exceptional values (like -1) are
included in the enumeration, since the compiler otherwise may not
include it in the valid range of the enumeration.
