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.
