This also adds some new ApiBase::PARAM_* constants to generate more
helpful help, and a method to override the default description message
for the use of ApiDisabled and ApiQueryDisabled.
Bug: 71638

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.

This adds a new hook called LanguageLinks which is called
whenever a list of language links is returned to the user.
This gives extensions the option to manipulate the links
on the fly.
Note that this change only covers the language links used
in OutputPage and by ApiParse. Adapting ApiQueryLangLinks is
left as a follow-up task.
As explained on bugzilla, this is a precondition to
allowing Wikibase/Wikidata to update languagelinks without
forcing a (redundant) re-parse of the page content.
This change also introduces the notion of link flags that
can be used to associate flags with language links. This
will be integrated with ParserOutput and OutputPage in a
follow-up.

The iwlinks and langlinks modules continue parameters imply ordering by
page then prefix then title. But in certain modes, the actual queries
use a different ordering, which may result in skipped or repeated
results.
This changeset fixes that. To do so, it needs to re-add an index
iwl_prefix_from_title which was mistakenly removed in 2010 (r69721). And
while it's doing that, it cleans up errors in the sqlite and postgresql
handling of the iwlinks indexes too.
Also, per Asher, make the iwl_prefix_from_title and
iwl_prefix_title_from indexes non-UNIQUE.

API was using SVN's version keyword which GIT does not support.
All related methods were either removed, or for those that
could have been used from extensions, emptied out.
api.php?version now shows unrecognized param warning.

* If a query module has 'continue' parameter, it will auto-report
that it has 'badcontinue' error.
* Added APIQueryBase::DieUsageContinueIf( $condition ) that shows
correct badcontinue error if $condition is true.

Doxygen choke on text enclosed by '<' and '>' since it tries to
interpret them as HTML or XML elements. This patch adds double quotes
in includes/api/*.php files around the two following strings:
<Firstname>.<Lastname>@gmail.com
<Firstname><Lastname>@gmail.com
Which becomes:
"<Firstname>.<Lastname>@gmail.com"
"<Firstname><Lastname>@gmail.com"
Tested locally, it prevents doxygen 1.8.0 related warnings.

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

and 'continue' for some prop-Modules
Due to missing change of the where for the query-continue in my first
patch, using dir=descending will end up in a loop

It's a parctice that dates back to 2006 when the API was first written, and frankly isn't covered by the coding conventions. Same thing with the docblocks, they're all copypasted with some bits changed and don't even make sense if you look at them in the genereated code docs.
I don't feel that any of us depend on this anymore (get a better IDE), so in the inerest of consistancy it's time we said goodbye to it.
* Introduced a "cache mode" concept to simplify the header generation code, and to avoid odd results when conflicting cache header requests are received from submodules, or at least to formalise the handling of such cases.
* Made the cache mode private by default, so that code written in ignorance of caching tends to be safe. If different query modules are used in a single request, private caching is preferred over public caching.
* Removed the "must-revalidate" option from all CC headers, this is really specific to page views with a hacked squid in front, I don't think it's applicable here.
* Made the watchlist module private. This is really the definition of private data. There's nothing in the HTTP spec that says the URL for a CC:public request is private and can't be leaked. CC:private provides protection against unknown proxy behaviour.
* In ApiQueryAllmessages: avoid calling $wgLang->getCode() to check if it's necessary to make a new $wgLang when lang= is specified, since this is the only thing that unstubs $wgUser.
* Removed "FIXME: should this check $user instead of $wgUser?" Answer is no.

the rest of MW on principle, but I'm not gonna bother myself." --Roan

If you're seeing this commit in blames, tell your blame tool to ignore
whitespace, e.g., git blame -w or svn blame -x -w.
* This means queries could possibly return fewer results than the limit and still set a query-continue
* Add iicontinue, rvcontinue, cicontinue, incontinue, amfrom to faciliate query-continue for these modules
* Implemented by blocking additions to the ApiResult object if they would make it too large
** Important things like query-continue values and warnings are exempt from this check
** RSS feeds and exported XML are also exempted (size-checking them would be too messy)
** Result size is checked against $wgAPIMaxResultSize, which defaults to 8 MB
For those who really care, per-file details follow:
ApiResult.php:
* Introduced ApiResult::$mSize which keeps track of the result size.
* Introduced ApiResult::size() which calculates an array's size
(which is the sum of the strlen()s of its elements).
* ApiResult::addValue() now checks that the result size stays below
$wgAPIMaxResultSize. If the item won't fit, it won't be added and addValue()
will return false. Callers should check the return value and set a
query-continue if it's false.
* Closed the back door that is ApiResult::getData(): callers can't manipulate
the data array directly anymore so they can't bypass the result size limit.
* Added ApiResult::setIndexedTagName_internal() which will call
setIndexedTagName() on an array already in the result. This is needed for the
'new' order of adding results, which means addValue()ing one result at a time
until you hit the limit or run out, then calling this function to set the tag
name.
* Added ApiResult::disableSizeCheck() and enableSizeCheck() which disable and
enable size checking in addValue(). This is used for stuff like query-continue
elements and warnings which shouldn't count towards the result size.
* Added ApiResult::unsetValue() which removes an element from the result and
decreases $mSize.
ApiBase.php:
* Like ApiResult::getData(), ApiBase::getResultData() no longer returns a
reference.
* Use ApiResult::disableSizeCheck() in ApiBase::setWarning()
ApiQueryBase.php:
* Added ApiQueryBase::addPageSubItem(), which adds page subitems one item
at a time.
* addPageSubItem() and addPageSubItems() now return whether the subitem
fit in the result.
* Use ApiResult::disableSizeCheck() in setContinueEnumParameter()
ApiMain.php:
* Use ApiResult::disableSizeCheck() in ApiMain::substituteResultWithError()
* Use getParameter() rather than $mRequest to obtain requestid
DefaultSettings.php:
* Added $wgAPIMaxResultSize, with a default value of 8 MB
ApiQuery*.php:
* Added results one at a time, and set a query-continue if the result is full.
ApiQueryLangLinks.php and friends:
* Migrated from addPageSubItems() to addPageSubItem(). This eliminates the
need for $lastId.
ApiQueryAllLinks.php, ApiQueryWatchlist.php, ApiQueryAllimages.php, ApiQuerySearch.php:
* Renamed $data to something more appropriate ($pageids, $ids or $titles)
ApiQuerySiteinfo.php:
* Abuse siprop as a query-continue parameter and set it to all props that
couldn't be processed.
ApiQueryRandom.php:
* Doesn't do continuations, because the result is supposed to be random.
* Be smart enough to not run the second query if the results of the first
didn't fit.
ApiQueryImageInfo.php, ApiQueryRevisions.php, ApiQueryCategoryInfo.php, ApiQueryInfo.php:
* Added continue parameter which basically skips the first so many items
ApiQueryBacklinks.php:
* Throw the result in a big array first and addValue() that one element at a time if necessary
** This is necessary because the results aren't retrieved in order
* Introduced $this->pageMap to map namespace and title to page ID
* Rewritten extractRowInfo() and extractRedirRowInfo() a little
* Declared all private member variables explicitly
ApiQueryDeletedrevs.php:
* Use a pagemap just like in Backlinks
* Introduce fake page IDs and keep track of them so we know where to add what
** This doesn't change the output format, because the fake page IDs start at 0 and are consecutive
ApiQueryAllmessages.php:
* Add amfrom to facilitate query-continue
ApiQueryUsers.php:
* Rewrite: put the getOtherUsersInfo() code in execute()
