Log Message:
make(1): clean up VarParseResult constants
The many constants were invented because at that time I didn't quite
understand the actual outcomes of Var_Parse that need to be
distinguished. There are only a few:
(1) Errors, whether they are parse errors, or evaluation errors or
undefined variables. The old constants VPR_PARSE_MSG and
VPR_UNDEF_MSG are merged into VPR_ERR.
(2) Undefined expressions in a situation in which they are allowed.
Previously the documentation for VPR_UNDEF_SILENT talked about
undefined expressions in situations where they were not allowed.
That case is fully covered by VPR_ERR instead.
(3) Errors that are silently ignored. These are probably bugs.
(4) Everything went fine, the expression has a defined value.
