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

Log Message:
make(1): don't modify the given line during Parse_DoVar

Placing null characters all over the line made the code hard to
understand.  The null characters were placed for top-level whitespace as
well as the operator.

Working with a read-only line makes it easier to inspect the parsing
state during debugging.

This change involves an additional bmake_malloc for each variable name.
This will be compensated later by extending the API of the Var module to
also accept a pair of pointers (start, end) as the variable name.
