* If the user specifically requests an empty list of namespaces, they
should get no pages.
* `ar_namespace` should always be in the query so MySQL can do a range
search instead of a full index scan.
* The example provided didn't match its description.

When generating titles rather than revids, it would be nice if we could
query with DISTINCT to get the titles directly instead of processing
every deleted revision for the title.
Sadly, it turns out this only works with dir=newer (dir=older is the
default). But that's probably better than nothing.

ApiResult was a mess: some methods could only be used with an array
reference instead of manipulating the stored data, methods that had both
array-ref and internal-data versions had names that didn't at all
correspond, some methods that worked on an array reference were
annoyingly non-static, and then the whole mess with setIndexedTagName.
ApiFormatXml is also entirely annoying to deal with, as it liked to
throw exceptions if certain metadata wasn't provided that no other
formatter required. Its legacy also means we have this silly convention
of using empty-string rather than boolean true, annoying restrictions on
keys (leading to things that should be hashes being arrays of key-value
object instead), '*' used as a key all over the place, and so on.
So, changes here:
* ApiResult is no longer an ApiBase or a ContextSource.
* Wherever sensible, ApiResult provides a static method working on an
arrayref and a non-static method working on internal data.
* Metadata is now always added to ApiResult's internal data structure.
Formatters are responsible for stripping it if necessary. "raw mode"
is deprecated.
* New metadata to replace the '*' key, solve the array() => '[]' vs '{}'
question, and so on.
* New class for formatting warnings and errors using i18n messages, and
support for multiple errors and a more machine-readable format for
warnings. For the moment, though, the actual output will not be changing
yet (see T47843 for future plans).
* New formatversion parameter for format=json and format=php, to select
between BC mode and the modern output.
* In BC mode, booleans will be converted to empty-string presence style;
modules currently returning booleans will need to use
ApiResult::META_BC_BOOLS to preserve their current output.
Actual changes to the API modules' output (e.g. actually returning
booleans for the new formatversion) beyond the use of
ApiResult::setContentValue() are left for a future change.

We don't have just one namespace like the code we copied this from. And
to avoid a repeat of bug 25702, we have to handle the case where the
title/prefix might be being transformed differently in all the requested
namespaces.

list=deletedrevs has always been an odd one: it pretends to be a prop
module sometimes in taking titles from ApiPageSet, but when the pageset
supplies no titles it acts like a list module. This causes problems
such as bug 71389, and makes the whole thing unnecessarily confusing.
The solution is to split the "prop" and "list" aspects into separate
modules: prop=deletedrevisions when input should come from ApiPageSet
and list=alldeletedrevisions when not.
At the same time, let's take advantage of the situation to clear up some
other bugs. And let's share the revision-formatting code with
ApiQueryRevisions instead of partially reimplementing it.
