API warnings and error messages are currently hard-coded English
strings. This patch changes that.
With a few exceptions, this patch should be compatible with non-updated
extensions:
* The change to ApiBase::$messageMap will blow up anything trying to
mess with it.
* The changes to the 'ApiCheckCanExecute' hook will cause a wrong
(probably unparsed) error message to be emitted for extensions not
already using an ApiMessage. Unless they're currently broken like
Wikibase.

Some generators (e.g. generator=recentchanges) in their default mode of
operation are particularly prone to not generating the same result set
on subsequent requests due to intervening activity on the wiki adding
new entries to the start of the list. We can mitigate this effect by
allowing such generators to provide "non-continuation" data to be used
if the generator isn't being continued.
ApiQueryRecentChanges and ApiQueryAllRevisions are updated to set this
new property. Other generators can easily be updated in the same way as
needed.
There isn't anything we can do about generators prone to having entries
added at random positions in the list rather than the beginning,
unfortunately.

Nothing in this patch should result in changed output for format=json or
format=php except as noted in RELEASE-NOTES-1.25, and changed output for
format=xml should be similar or cosmetic. However, other code accessing
the result data directly may need to be updated.

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.
