mk/ChangeLog since bmake-20250804

2025-11-18  Simon J Gerraty  <sjg@beast.crufty.net>

	* sys.vars.mk: set MAKE_POSIX_SHELL to 1 if .SHELL is POSIX, 0 if not.
	set isPOSIX_SHELL for use in target scripts.

	* meta.stage.mk: set MAKE_POSIX_SHELL if needed.

	* install-new.mk: use ${isPOSIX_SHELL:Ufalse} to see if we can
	avoid running 'expr'.

	* install-new.mk: Allow use of cp or mv - controlled by CPMV_OP
	(default mv).

2025-11-13  Simon J Gerraty  <sjg@beast.crufty.net>

	* sys.vars.mk: add M_sh1 so we can handle older bmake that does
	not support :sh1

2025-11-11  Simon J Gerraty  <sjg@beast.crufty.net>

	* install-mk (MK_VERSION): 20251111

	* meta2deps.sh: reset some vars for each new meta file
	set meta_file to path of meta file.
	If meta2deps appears in DEBUG_SH set -x.

2025-09-16  Simon J Gerraty  <sjg@beast.crufty.net>

	* options.mk: Add OPTIONS_DEFAULT_DEPENDENT_REQUIRED of the form
	OPTION/REQUIRED[/VALUE]
	if OPTION is $VALUE (default is "yes"), then REQUIRED must be too.
	We add OPTIONS_DEFAULT_DEPENDENT_REQUIRED (sans any /{yes,no}) to
	OPTIONS_DEFAULT_DEPENDENT so DEPENDENT/REQUIRED follow the same
	processing.

	Also add OPTIONS_FORCED_VALUES of the form OPTION/{yes,no}
	we add any OPTIONS_FORCED_NO and OPTIONS_FORCED_YES before
	processing.

	Simplify the processing of OPTIONS_DEFAULT_VALUES and
	OPTIONS_DEFAULT_DEPENDENT by splitting the tuples and use two
	iterator variables in the .for loops.

2025-08-09  Simon J Gerraty  <sjg@beast.crufty.net>

	* install-mk (MK_VERSION): 20250808

	* replace sjg license with just BSD-2-Clause SPDX tag

Lots of code refactoring, simplification and cleanup.
Lots of new unit-tests providing much higher code coverage.

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.
