variables that use the :sh modifier. This still causes expansion to only
happen when referenced, and has the advantage of being :Q-safe.
Bring back the changes from revision 1.19 of mk/subst.mk now that the
problem noted above has been fixed. This passes the buildlink-unwrap
regression test.

evident when running "make regress" in regress/buildlink-unwrap.
Mea culpa.
"foo" as "foo.subst.sav". Implement SUBST_POSTCMD, which by default
cleans up these leftovers. If you need to keep them around, e.g.
while debugging, set it to ${DO_NADA}.

Also revert revision 1.6 as part of the overall change, as I suspect
the change might be unnecessary. While I'm not 100% sure, this does
just revert to the previous behaviour.
before subst'ing it.
previously, only a warning would be printed and the .subst_done
cookie(s) would be created, indicating that the subst target was
successful when it really was not.
output of file(1) which reports too many false negatives (not
detecting a file as a text file when it really is).
package developers are aware of which files the subst operation
applies to, since they need to specify the filenames, so this test is
not really required.
it's also not inconceivable that one would want to subst over a
non-text file, which is now possible.
pipeline that takes stdin, performs the substitions and writes the result
to stdout. It defaults to ${SED} ${SUBST_SED.<class>}. Use this variable
to replace the sed command with something else, like an awk process.
facility for different classes of files in ${WRKSRC}. For each class of
files, a target <class>-subst is created to perform the text replacement.
The following variables are used:
SUBST_STAGE.<class>
"stage" at which we do the text replacement, e.g. pre-configure,
post-build, etc.
SUBST_MESSAGE.<class>
message to display, noting what is being substituted
SUBST_FILES.<class>
files on which to run the substitution; these are relative to
${WRKSRC}
SUBST_SED.<class>
sed(1) substitution expression to run on the specified files
This basically extracts a useful piece of code from bsd.buildlink2.mk and
puts it in a place that allows it to be more widely used, and so that the
functionality doesn't depend on USE_BUILDLINK2 being defined.
