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.
