Modified Files:
        src/usr.bin/make: arch.c buf.c compat.c cond.c dir.c for.c job.c main.c
            make.c meta.c nonints.h parse.c str.c var.c

Log Message:
make(1): clean up code stylistically

* Replace character literal 0 with '\0'.
* Replace pointer literal 0 with NULL.
* Remove redundant parentheses.
* Parentheses in multi-line conditions are not redundant at the
  beginning of a line.
* Replace a few !ptr with ptr == NULL.
* Replace a few ptr with ptr != NULL.
* Replace (expr & mask) == 0 with !(expr & mask).
* Remove redundant braces for blocks in cases where the generated code
  stays the same.  (Assertions further down in the code would get
  different line numbers.)
* Rename parameters in CondParser_String to reflect the data flow.
* Replace #ifdef notdef with #if 0.

The generated code stays exactly the same, at least with GCC 5.5.0 on
NetBSD 8.0 amd64 using the default configuration.
