Rework mirrors page:

- Apply coding scheme used on other pages

 - Add much more information to 'userspace' about
   mirrors, why they might get delisted, the service
   they provide, etc. Also more information on the
   role of the default language.

 - Depend only on mirror URLs, and the functions
   now capable of providing information about any
   mirror given it's URL. This makes this page
   totally independent on the $MIRRORS array's
   internal structure. Now it only relies on the
   fact, that it's an associative array, with the
   keys as the mirror URLs

 - Do list special mirrors, but don't list outdated
   mirrors. This is part of the modifications to move
   from using the "special mirror" mark to delist a
   mirror. The new array structure contains the status
   information now, so we can depend on it.

At last, php.net will be listed on php.net as the
current mirror, and on other mirror's as being a
mirror site.

-Here you can find more information about the mirrors of php.net.
+ Here you can find information about the mirrors of php.net. This table only
+ lists the official mirrors, registered in our database. The mirrors automatically
+ detected to be outdated or disfunctional are not listed for your convinience, so
+ there may be a mirror (or some mirrors) with problems in your country additionaly
+ to those listed here. Therefore if you cannot find mirror sites in your country
+ here, or the mirror site you used seems to be disappeared, check back later.
 </p>
 <p>
-Pick a mirror site close to you (the current mirror is highlighted), or visit
-the provider's homepage. If you are interested in hosting a mirror of this site, 
-<?php print_link("/mirroring.php", "here's how"); ?>.
+ We would like to advice you to choose a mirror site close to use in your
+ everyday work. All mirror sites are expected to provide the same service
+ (with the possible exception of local search support, in which case the
+ main site performs the search). This means that you don't loose anything,
+ if you go with a local mirror site, but you gain speed. The current mirror
+ is highlighted in the list below.

+ Mirror sites also have default language settings, so shortcut navigation
+ services provide you results in that language. See the
+ <a href="/urlhowto.php">URL shortcuts page</a> for examples of this behaviour.
