Make obsolete site object can be created

Per discussion, this patch makes it possible to create an obsolete site object while the site object will be prevented from writing. In other words, it will be a read-only site. Consequently, this patch solves bug 55146. Note that although obsolete sites now become readable, they will not be in site.languages().

In addition, this patch makes pagelanglinks() return only non-obsolete sites by default to make old scripts still functional, but it adds a parameter to suppress this functionality.
