Uses new PHP 5.6 syntax like ...parameter unpacking and
calling anything looking like a callback to make the code more readable.
There are much more occurrences but this commit is intentionally limited
to an easily reviewable size.
In one occurrence, a simple conditional instead of trickery was much more readable.
This patch finishes all the easy stuf in the core, the remainder is either unobvious
or would result in smaller readability gains. It will be carefully dealt with in
further commits.

`$a <=> $b` returns `-1` if `$a` is lesser, `1` if `$b` is lesser,
and `0` if they are equal, which are exactly the values 'sort()'
callbacks are supposed to return.
It also enables the neat idiom `$a[x] <=> $b[x] ?: $a[y] <=> $b[y]`
to sort arrays of objects first by 'x', and by 'y' if they are equal.
* Replace a common pattern like `return $a < $b ? -1 : 1` with the
new operator (and similar patterns with the variables, the numbers
or the comparison inverted). Some of the uses were previously not
correctly handling the variables being equal; this is now
automatically fixed.
* Also replace `return $a - $b`, which is equivalent to `return
$a <=> $b` if both variables are integers but less intuitive.
* (Do not replace `return strcmp( $a, $b )`. It is also equivalent
when both variables are strings, but if any of the variables is not,
'strcmp()' converts it to a string before comparison, which could
give different results than '<=>', so changing this would require
careful review and isn't worth it.)
* Also replace `return $a > $b`, which presumably sort of works most
of the time (returns `1` if `$b` is lesser, and `0` if they are
equal or `$a` is lesser) but is erroneous.

The label is already a Message at this point. For Messages that
are not RawMessages, the call to wfMessage() does not do any harm.
However, for RawMessages, it causes the label to appear in <>.
Removing the call to wfMessage() does not harm regular Messages
and fixes the problem for RawMessages.

If no AuthenticationRequest requires a separate login button, it
shouldn'tbe visible. This is, for example, the case, when only
link providers are used, that require the user to redirect to a third
party site, as it usually just shows a single submit button.
In this case, the login button is still visible because of other additional
fields, such as the remember me button. This change checks each primary
authentication provider, if it provides its provide his own submit
button or not, and if so, removes the login button completely.

It's possible that an authentication extension implements its own HTMLForm classes
for a submit button or info field. To omit the default submit button of HTMLForm
in these cases, too, it's necessary to check if one of the provided HTMLForm field
classes inherit from HTMLSubmitField or HTMLInfoField (assuming, that subclasses
in extensions inherit from one of them).

AuthManager uses a status which is OK but not good for authentication
data which is discouraged but still accepted for authentication.
Users should not be allowed to change credentials into such invalid state.
This change brings the web logic and the AuthPlugin fallback in sync with
the API which already used the stricter check.

Rewrite authentication-related special pages to use AuthManager.
All the changes mentioned below only take effect when
$wgDisableAuthManager is false.
LoginForm is rewritten to use HTMLForm and split into UserLogin
and CreateAccount; ChangePassword and PasswordReset are rewritten;
ChangeEmail and Preferences are updated. Four new special pages
are added to handle the new capabilities of AuthManager (linked
accounts, secondary authentication providers): LinkAccounts,
UnlinkAccounts, ChangeCredentials, RemoveCredentials.
The old form-based hooks (ChangePasswordForm, UserCreateForm,
UserLoginForm) are deprecated. A new, more generic hook is
available to alter the forms (AuthChangeFormFields);
form changes that involve new fields should be done via
$wgAuthManagerConfig.
UserLoginComplete is limited to web-based login; for more
generic functionality UserLoggedIn can be used instead.
Hooks that assume password-based login (PrefsPasswordAudit,
AbortChangePassword) are removed; the first functionality
is replaced by ChangeAuthenticationDataAudit, the second is
handled by AuthManager. LoginPasswordResetMessage is removed,
the functionality can be recreated via authentication providers.
There are several smaller backwards incompatible changes:
* Adding fields to the login/signup forms by manipulating the
template via the extraInput/extrafields parameters is not
supported anymore. Depending on the authn configuration the
login/signup process might be multistep and it would be
complicated to ensure that extensions can access the data
at the right moment. Instead, you can create an
AuthenticationProvider which can define its own fields and
process them when the authentication is over.
(There is B/C support for a transitional period that works with
the default login form, but might break with configurations that
require multiple steps or redirects.)
* Removed cookie redirect check. This was added in 2003 in 9ead07fe9
for the benefit of bots, but with MediaWiki having an API these days
there is little reason to keep it. Same for the wpSkipCookieCheck
flag (added in 2008 in 29c73e8265).
* Instead of embedding a password field on sensitive special pages
such as ChangeEmail, such pages rely on AuthManager for elevated
security (which typically involves requiring the user to log in again
unless their last login was more than a few minutes ago).
Accordingly, wgRequirePasswordforEmailChange is removed.
* Special:ChangePassword requires login now.
* Special:ResetPassword now sends a separate email to each user when called
with a shared email address.
* the Reason field had a message with 'prefsectiontip' class
which was sorta broken but used in extensions for formatting.
HTMLForm does not support that, so this commit turns it into a help message
which will break formatting. See https://gerrit.wikimedia.org/r/#/c/231884
