When parsing variable assignments other than := and if
value contains '$' attempt Var_Subst the same as for :=,
if the value does not parse correctly, we get a fatal error
including file an line number.
This can greatly help with finding the cause of problems.

Allow tracking of max chain length, to see how well the hash
tables are working.
Pull the actual hash operation into a marco so it can be
easily changed - for experimenting.
The current hash, is pretty good.

make(1) has commands .include <file> and .include "file",
but the manpage was (inconsistently) rendering <file> with
angle-brackets (e.g. in UTF8 ) and "file" with curly-quotes
in HTML output (but not text).
This is an attempt to fix that and output only literal <file>
and "file" as is actually required in the makefile.fileoutput,

that passing variables to recursive makes with :q works as expected.
- Revert :Q to work as before.
- Adjust makefiles that use recursive make to use :q

:range replaces var value with an integer sequence one per word
in the current var value.
:_ stores the current var value in $_ so that it can be referred to
later in the modifier series.

The filter is applied to paths Read or Excuted, and if it expands to
nothing, the entry is skipped.
For example; dirdeps.mk can set this to:
.MAKE.META.IGNORE_FILTER = M*/${.MAKE.DEPENDFILE_PREFIX}*
when checking if DIRDEPS_CACHE is up to date, where only Makefile.depend*
are of interest.
Both meta_create() and meta_oodate() now share meta_needed()
to indicate if a .meta file is needed.
This allows for deciding that missing .meta file is cause of out-of-date.
The new knob 'missing-meta' controlls this, and is off by default
since the side effect files of generators like yacc will typically need
.NOMETA to avoid problems.
This however makes it much easier for folk to switch back and forth
with meta mode (eg. FreeBSD's normal build can leverage meta mode for
improved reliablility without need to clean).
Also if .MAKE.MODE does not contain 'nofilemon', the knob
'missing-filemon' allows control as to whether missing filemon data
should cause the target to be out-of-date.
Again off by default.
Like .sinclude missing file will be ignored.
Like .depend stale dependencies will be ignored.
Allows better implementation of auto depend.

Also fix handling to match the behavior described in the comment
of JobPrintCommand (only matters if shell sets hasErrCtl).
A better long term solution is needed since the current behavior
is sub-optimal wrt '-' and different from all other makes.

I was originally intending to preserve some of Jarmo Jaakkola's notes
on POSIX make from the PR 49085 changes... but really there's no point
wandering into details about $? and such when the big picture is
"almost everything in this manual works only in BSD make".
Maybe the exact details can be stuffed into a chapter of the mythical
make reference manual if that ever gets (re)written.
