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: directive-undef.mk,v 1.10 2021/02/16 18:02:19 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.

# Tests for the .undef directive.
Import bmake-20210110 Quite a lot of churn on style, but lots of good work refactoring complicated functions and lots more unit-tests. Thanks mostly to rillig at NetBSD Some interesting entries from ChangeLog o .MAKE.{UID,GID} represent uid and gid running make. o allow env var MAKE_OBJDIR_CHECK_WRITABLE=no to skip writable checks in InitObjdir. Explicit .OBJDIR target always allows read-only directory. o add more unit tests for META MODE Change-Id: I4d3bcf08b4c864d98b343f602efe5a75dbfa7a94

# Before var.c 1.737 from 2020-12-19, .undef only undefined the first
# variable, silently skipping all further variable names.
#
# Before var.c 1.761 from 2020-12-22, .undef complained about too many
# arguments.
#
# Since var.c 1.761 from 2020-12-22, .undef handles multiple variable names
# just like the .export directive.
