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.

There are cases where the list of values for a 'prop' parameter may be
manipulated by a subclass or by a hook function of some sort. Rather
than requiring the subclass/hook to completely replace a monolithic i18n
message, let's add the possibility of separate messages for each value
in the list.

The format for 'props' was never specified and the list for 'errors' is
impossible to keep updated when considering that many errors come from
MediaWiki backend code and extension hook functions. And since there
doesn't seem to be any real use case for either of these, let's just
kill both of them instead of wasting effort on trying to fix them.
Note that neither getResultProperties nor getPossibleErrors are called
from any extensions in gerrit, and none of the other deprecated methods
are called outside of the implementations of those two methods. Removing
the obsolete methods is left to the maintainers of the extensions, as
keeping them hurts nothing and is needed to maintain compatibility with
earlier versions of MediaWiki.

Which type is used depends on the ApiModuleManager responsible for
the API module. There are two managers, one in ApiMain and one in
ApiQuery. Both contain a list of API modules they instantiate.
Both use $this as the first parameter in the constructors of the
individual modules. There is no other regular way to instantiate the
modules, so we know the type must either be ApiMain or ApiQuery.
The lists don't intersect.
I would have prefered the naming scheme $mainModule for ApiMain
modules and $queryModule for ApiQuery modules but since this
doesn't add much I left the shorter variable names untouched.

Swapped some "$var type" to "type $var" or added missing types
before the $var. Changed some other types to match the more common
spelling. Makes beginning of some text in captial.
Also added some missing @param.

API queries must be completely ordered for proper behavior; otherwise
you may get into a situation where a query returns the same continuation
value that was provided. Various modules that have been using timestamps
in/as their continuation parameter can easily run into this problem.
Normally we'd have to add additional fields to the relevant indexes to
be able to make this work without having filesorting queries (which
MySQL really doesn't do well, it fetches all matching rows and only
applies the limit after[1]). But InnoDB has a "feature" where it
effectively appends the table's primary key to all other indexes,[2]
which makes these queries be properly indexed in that situation.
Apparently we're ok with this, since Icc43b62f was merged depending on
this feature.
Also, this change fixes some MySQLisms and other oddities done to
ApiQueryRecentChanges in Icc43b62f.

ApiQueryBase::titlePartToKey now allows an extra parameter that
indicates the namespace in order to properly capitalize the title part.
This allows list=allcategories, list=allimages, list=alllinks,
list=allpages, list=deletedrevs and list=filearchive to
handle case-sensitivity properly for all parameters.

While the change in Ic980fd71 makes sense since MediaWiki stores the
hashes with lowercase letters, historically aisha1 and fasha1 accepted
both upper and lowercase because wfBaseConvert accepts both.
To avoid a backwards compatibility break, let's adjust the code to
explicitly lowercase the input for those parameters. And for good
measure, let's also accept both cases for the corresponding sha1base36
parameters.

New parameter 'sort' that defaults to 'name' so if not specified it will
act exactly as before.
Changes in the access to $params['dir'] to a boolean variable
$ascendingOrder in a try to be more meaningful.
Some existing filtering parameters are mutually exclusive with new ones.
The reason is because the table is sorted by name, as primary key, while
sorting by timestamp use the timestamp or usertext_timestamp index which
is not the primary key, thus filtering and ordering by different indices
doesn't make an efficient index usage.
Exceptions are:
* mime: disabled in Miser Mode
* size: although there's apparently no use for this when sorting by
timestamp, there's an index on that and the EXPLAIN doesn't use filesort
algorythm (unlike other combinations):
EXPLAIN
select img_name, img_user_text, img_timestamp
from image
where img_size>=1000 and img_size<=20000
and img_timestamp > '20120916153705'
ORDER BY img_timestamp\G
* Same for sha1 (see comment on Patchset 1)
In function run:
* Added USE INDEX query options when sort=timestamp to ensure the proper
index is being used.
* Table selection and result fields moved at top, then filter parameters,
and finally order by and options.
Parameter description and definition sorted by purpose: sort and dir
first, then pagination, result fields, filters and limit.

API continuation parameters encode sufficient state for a subsequent
query to continue where the previous one left off; this may sometimes
include page titles, with or without the namespace. Given that these
page titles are already in the exact format required for the next
request's SQL query, it is not necessary to "normalize" them in any way.
And if normalization does more than just change spaces to underscores or
vice versa (e.g. it canonicalizes namespace aliases or capitalizes the
first letter of the title), it can be actively harmful: see bug 36987
and bug 29290.
Note this patch involves a breaking API change: the values for the
"continue" parameter of various modules have been changed, and some
modules will now return "continue" as the continuation parameter instead
of reusing "from".
Note this patch also corrects a minor logic bug in ApiQueryAllLinks,
changing ">" to ">=". The line is being changed anyway, so I didn't
bother doing a separate changeset.

A thumb is only generated when prop=url and a urlwidth is given. Adding
a hint to param description.
list=allpages does not have a urlwidth param and therefor cannot get the
thumbmime, adding thumbmime to the filter list to remove it from output
Change-Id: Ic1dbdb9b07f6325756058d6a0aa6ea148499fdfb
Added information about the properties of the results of API calls
to action=paraminfo, including information about "property groups":
what should the prop parameter be set to to get that property.
Uses the same format for types as parameters already do.
The output format of some modules doesn't fit this, so the result
properties for them weren't added, or only partially.
Partially implemented modules:
* expandtemplates:
parsetree is in its own tag
* protect, allusers, backlinks, deletedrevs, info, imageinfo,
logevents, querypage, recentchanges, revisions, searchinfo,
usercontribs, userinfo, users, watchlist, upload:
response with partially complex structure
Not implemented modules:
* feedcontributions, feedwatchlist, opensearch, rds:
non-standard reponse
* help:
error is normal response; not very useful for automated tools anyway
* paraminfo, parse, pageprops, siteinfo, userrights:
response with complex structure
