[PATCH setup, v2] site.cc, site.h: code cleanup


Remove site_list_type::init(), which was introduced to work around a
problem with gcc-2.95.

Add a bool member 'from_mirrors_lst' to the site_list_type class.  Use
it to distinguish mirrors listed in mirrors.lst from user-added sites.
This replaces the (undocumented) use of
site_list_type::servername.size() for this purpose.

When registerSavedSite is called on a URL that's already in
'all_site_list', add the version from 'all_site_list' to 'site_list'
rather than adding a temporary version that contains no information
other than the URL.

Similarly, if the user adds a site that was already in
'all_site_list', don't replace the existent version with the new one
(which contains only the URL).
