Merge commit 'ee914ef902ae018bd4f67192832120f9bf05651f' into new_merge

Update to bmake-20200902

Lots of code refactoring, simplification and cleanup.
Lots of new unit-tests providing much higher code coverage.
All courtesy of rillig at netbsd.

Other significant changes:

o new read-only variable .SHELL which provides the path of the shell
used to run scripts (as defined by the .SHELL target).

o variable parsing detects more errors.

o new debug option -dl: LINT mode, does the equivalent of := for all
variable assignments so that file and line number are reported for
variable parse errors.

Update to bmake-20200710

Key changes include reduced noise at end of failed build log
and avoid evaluation of unnecessary terms in conditionals.
In META MODE; a target flagged .META is out-of-date if meta file
is missing
