bug#32849: 26.1; xref-marker-ring-length user option doesn't have setter

Patches attached.

Of note:

I added a ring-resize function.

I wrote tests with names function-to-test/case-tested.  I'm not sure
if this violates style policies for tests.  It seems like existing
code tests multiple cases in a single test, but I find separate tests
easier to understand when they regress.  The / makes the test names
easier to read.

I based this off of 26 (as I think this is a minor bugfix/feature add).
