* Add a void return hint to methods that are not meant to return
anything. This helps catch accidental return statements in the
future, lets Phan better understand how methods are meant to be
used, and might also allow PHP to better optimise the compiled
code form (speculation).
I did not, however, add it to publicly extended methods as that
might mess with strict mode.
* Remove the internal getResourceLoader() method from MessageBlobStore.
This has been redundant since 3edaa0b37c.
The method was protected, and not considered stable to subclass
for extensions. Hence not a breaking change.
* Add Throwable typehint to formatException() and friends.
This is the narrowest one I could add given that the methods
called from here already enforce the same typehint.
Update the doc to match for now. There isn't a reason right now
to limit this only to Exception, and given this is the method
and not the catch statement itself, does not change behaviour.
* Remove unused ResourceLoader->getHookContainer().
Added within 1.35 cycle, safe to remove.
* Remove unexpected `@since` for `@internal` getHookRunner().
* Remove redundant `@internal` from ResourceLoaderMwUrlModule
methods, which itself is already `@internal`.

This change allows to use the context in the functions.
The following internal static functions from ResourceLoader get now a
reference to the ResourceLoaderContext object:
* makeLoaderImplementScript
* makeLoaderStateScript
* makeLoaderRegisterScript
* makeLoaderSourcesScript
ResouceLoader::encodeJsonForScript is duplicated to
ResourceLoaderContext::encodeJson loading the debug mode from context.
ResourceLoader::encodeJsonForScript is kept for other usages without
context.
The debug mode is loaded from $context->getDebug() instead of from
ResourceLoader::inDebugMode(). This does not support to enable the debug
mode by setting the cookie 'resourceLoaderDebug' or the configuration
variable wgResourceLoaderDebug. Only the URL parameter debug=true
enables the debug mode. This should be sufficient for the subsequent
ResourceLoader requests. The tests don't need the global variable
wgResourceLoaderDebug anymore. The initial ResourceLoader context in
OutputPage still uses ResourceLoader::inDebugMode() with cookie and
global configuration variable.
This change adds the parameter $context with a ResourceLoaderContext
object to ResourceLoaderModule::getDeprecationInformation and deprecates
omitting the parameter. Ifa1a3bb56b731b83864022a358916c6aca5d7c10
updates this in extension ExtJSBase.

* Add license header where missing.
* Add missing `@since` (1.17 for most classes), except
ResourceLoaderLessVarFileModule since 1.32 (1bc62c548c).
* Remove duplicate file-level description for class-only files,
merge with the class description instead.
* Remove my own `@author` annotation from one file.
* Mark core's own FileModule subclasses as `@internal`, except
for the following which we support use of in extensions:
ResourceLoaderLessVarFileModule,
ResourceLoaderOOUIIconPackModule, and
ResourceLoaderWikiModule.

This greatly simplifies logic required to compute module versions.
It also makes it significantly less error-prone.
Since f37cee996e, we support hashes as versions (instead of timestamps).
This means we can build a hash of the content directly, instead of compiling a
large array with all values that may influence the module content somehow.
Benefits:
* Remove all methods and logic related to querying database and disk for
timestamps, revision numbers, definition summaries, cache epochs, and more.
* No longer needlessly invalidate cache as a result of no-op changes to
implementation datails. Due to inclusion of absolute file paths in the
definition summary, cache was always invalidated when moving wikis to newer
MediaWiki branches; even if the module observed no actual changes.
* When changes are reverted within a certain period of time, old caches can now
be re-used. The module would produce the same version hash as before.
Previously when a change was deployed and then reverted, all web clients (even
those that never saw the bad version) would have re-fetch modules because the
version increased.
Updated unit tests to account for the change in version. New default version of
empty test modules is: "mvgTPvXh". For the record, this comes from the base64
encoding of the SHA1 digest of the JSON serialised form of the module content:
> $str = '{"scripts":"","styles":{"css":[]},"messagesBlob":"{}"}';
> echo base64_encode(sha1($str, true));
> FEb3+VuiUm/fOMfod1bjw/te+AQ=
Enabled content versioning for the data modules in MediaWiki core:
* EditToolbarModule
* JqueryMsgModule
* LanguageDataModule
* LanguageNamesModule
* SpecialCharacterDataModule
* UserCSSPrefsModule
* UserDefaultsModule
* UserOptionsModule
The FileModule and base class explicitly disable it for now and keep their
current behaviour of using the definition summary. We may remove it later, but
that requires more performance testing first.
Explicitly disable it in the WikiModule class to avoid breakage when the
default changes.

Follows-up f37cee996e which replaced the getHashMtime() and
getDefinitionMtime() methods with dummies that always return 1.
These getModifiedTime() implementations were only tracking the
definition summary or custom hash, which is already tracked
by getVersionHash().
Notes:
* SpecialCharacterDataModule: This one was odd as it was tracking
both the mtime *and* the file contents.
* UserCSSPrefsModule/UserOptionsModule: Remove redundant caching.
Already taken care of by getVersionHash() as of f37cee996e.

* Use time() instead of:
- wfTimestamp()
- wfTimestamp( TS_UNIX )
- wfTimestamp( TS_UNIX, 0 )
- wfTimestamp( TS_UNIX, time() )
- intval( wfTimestamp( TS_UNIX, time() ) )
* Consistently use 1 as default instead of 0. Previously the
unwritten convention was that anything "final" max()'ed with 1,
and any internal method would use 0, but this wasn't applied
consistently made it fragile. There doesn't seem to be any
value in returning 0 only to have it maxed up to 1 (because if
the 0 would ever make it out alive, we'd be in trouble).
* wfTimestamp returns a string for TS_UNIX. In PHP this doesn't
matter much. In fact, max() takes number-like integers so
transparently, it even preserves it:
> max( 1, 3, '2' );
< 3
> max( 1, '3', 2 );
< "3"
Just cast it in one place at the very end (StartupModule)
instead of doing intval( wfTimestamp() ).
* Fix weird documentation claiming getModifiedTime can return
an array, or mixed.
* Remove 'version > 1 ? version : 1' logic in
ResourceLoader::makeLoaderRegisterScript. The client doesn't
have "0 means now" behaviour so this isn't needed. And the method
was only doing it for variadic argument calls.
Removal of quotes around timestamps reduced the size of the startup
module from 26.8KB to 25.9KB before gzip. After gzip the size was
and still is 5.7KB, though. (From 5456 bytes to 5415 bytes.)

We currently embed the full set of user options in a <script> tag in the HTML
output of every page. This is grossly inefficient, because the full set of
options is usually largely made up of site defaults which the user hasn't
customized.
So instead of doing that, let's emit the default options using one
ResourceLoader module and then apply the user's customizations on top.
This has the effect of slightly increasing the total bytes of JavaScript code
(because options that the user has customized will be emitted twice: once with
their default value in the user.defaults module, and then again with the
customized value in user.options). But this is more than offset by the
fact that the bulk of user options code (~4 kB uncompressed on enwiki) becomes
cacheable across requests.
Bonus round:
* Varnish gets to cache 4 kB fewer per page.
* Changes to the default options don't take 30 days to propagate.
