This is v3 of the struct value series.  The original cover letter is
below.

This series changes many value-related functions to be methods.  It
also moves the definition of struct value to value.h, so that callers
will benefit by inlining the smaller methods.  The members of value
are all made private at the end of the series.

It's difficult to decide exactly which value functions ought to be
converted, because there are so many.  In the end I chose a relatively
minimal approach -- only those that require direct access to the inner
workings of value.

It's possible, even easy, to convert more functions.  If there are
some in particular that seem worthwhile, let me know.

I tacked on one small cleanup at the end of this series, but as it was
already fairly long, I didn't try to do all the possible cleanups.
For example, many things could use bool, some of the setter functions
could be removed in favor of specialized constructors, etc.

Regression tested on x86-64 Fedora 36.

Tom
