The ksort() here was causing the order to be enforced as
alphabetical instead of preserving the original order.
The order usually doesn't matter, except with regards to handling
of duplicates. Due to Parsoid normalising external links to interwiki
links, it has to do a reverse lookup. In doing so it has to decide
which one to prefer. It currently picks the first match from the
API request for meta=siteinfo&siprop=interwikimap, which didn't
match the defined order in the actual Interwiki map due to ksort()
being called in getAllPrefixes().
Sort in this function was originally introduced in 2010 with
commit 844e7c83e4 (2011; r92528; T21838), which is otherwise unrelated
and left no rationale.
The existing unit tests needed to be adjusted slightly as they
assumed alphabetical order. While it appeared they were also defined
in alphabetical order, this was merely the order of the variable
creation. The effective order is preserved within locals and globals,
but overall globals come before locals.
Also removed the duplicate test for Hash and CDB in InterwikiTest
that belongs in ClassicInterwikiLookupTest instead.

This is used for lookup in a CDB file or PHP static array.
In neither case is the key created by wfMemcKey() or any other
implementation of BagOStuff::makeKey().
This is already broken if:
* An interwiki prefix were to contain characters not supported by
Memcached.
* An interwiki prefix and wikiid together are too long for Memcached.
* If the site has wgCachePrefix configured, which overrides the
wfWikiID() namespace makeKey() normally uses.
dumpInterwiki.php does not use wfMemcKey() either (and should not).
This was simply here as leftover from many rewrites ago, its
only purpose is to create wikiid + prefix joined by colon.

Most of these are simply changing annotations to reflect
reality. If a function can return false to indicate failure
the @return should indicate it.
Some are fixing preg_match calls, preg match returns 1, 0 or false,
but the functions all claim to return booleans.
This is far from all the incorrect return types in mediawiki, there
are around 250 detected by phan, but have to start somewhere.

This is more consistent with LoadBalancer, modern, and inclusive
of master/master mysql, NDB cluster, and MariaDB galera cluster.
The old constant is an alias now.

This keeps the existing app logic for looking up interwiki information
intact in ClassicInterwikiLookup. The idea is to seamlessly switch to a new
implementation when it becomes available, while also allowing us to
switch back in case of problems.
