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.

/* $NetBSD: enum.h,v 1.19 2021/03/15 16:00:05 rillig Exp $ */
Import 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 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.
