    Import bmake-20210621
    
    Lots more unit tests and code cleanup
    
    Relevant changes from ChangeLog
    
            o job.c: Print -de error information when running multiple jobs
            o var.c: only report error for unmatched regex subexpression
            when linting (-dL) since we cannot tell when an unmatched
            subexpression is an expected result.
            reduce memory allocations in the modifiers ':D' and ':U'
            reduce memory allocation and strlen calls in modifier ':from=to'
            in the ':Q' modifier, only allocate memory if necessary
            improve performance for LazyBuf
            reduce debug logging and memory allocation for ${:U...}
            reduce verbosity of the -dv debug logging for standard cases
            fix double varname expansion in the variable modifier '::='
            o var.c: avoid evaluating many modifiers in parse only mode
            in strict mode (-dL) many variable references are parsed twice,
            the first time just to report parse errors early, so we want to
            avoid side effects and wasted effort to the extent possible.
