        src/usr.bin/make: cond.c nonints.h parse.c var.c

Log Message:
make: convert VarEvalFlags back into an enum, but not a bit-set

As was apparent in VarEvalFlags_ToString, a bit-set was not the best
data type since most of the flags were not freely combinable.  The two
flags that could be combined were keepDollar and keepUndef, but even
these have distinguished names in the debug log.

The downside of struct bit-fields is that they need extra helper
functions in C90 (see nonints.h).  Exchange these for a few helper
functions in var.c, to keep the code outside var.c simple.

No functional change.
