Fix documentation build with older docbook-xsl Commit b0f0a9432d0 backpatched some code from upstream DocBook XSL to our customization layer. It turned out that this failed to work with anything but the latest DocBook XSL upstream version (1.79.*), because the backpatched code references an XSLT parameter (autolink.index.see) that is not defined in earlier versions (because the feature it is used for did not exist yet).
There is no way in XSLT to test whether a parameter is declared before the stylesheet processor tries and fails to access it. So the possibilities to fix this would be to either remove the code that uses the parameter (and thus give up on the feature it is used for) or declare the parameter in our customization layer. The latter seems easier, and with a few more lines of code we can backport the entire autolink.index.see feature, so let's do that. (If we didn't, then with older stylesheets the parameter will appear as on, but it won't actually do anything, because of the way the stylesheets are laid out, so it's less confusing to just make it work.) With this, the documentation build should work again with docbook-xsl versions 1.77.*, 1.78.*, and 1.79.* (which already worked before). Version 1.76.1 already didn't work before all this, so was not considered here.
