There were some cases where a negative limit could be passed in. Which
would happily make the query explode.
This is just a quick hack to make sure it never is negative.

Avoids directly getting the token again. We just inserted it so it and
have all the info. So that query is just a waste.

Some user backends (like the database backend) allow us to obtain a user
case insensitive. However the UID itself is case sensitive.
Example:
* create a user User1
* login as User1
- This results the data/User1 folder to be created etc
* now have some code somewhere that obtains the userFolder (from
IRootFolder) but pas in 'uSER1' as uid
- The code will check if that is a valid user. And in this case it is
since User1 and uSER1 both map to the same user
- However the the UID in the user object is used for the folder a new
folder fill be create data/uSER1
With this PR this is avoided now. Since we obtain the real UID casing in
the backend before creating the user object.

If we hit an expired token there is no need to continue checking. Since
we know it is a token.
We also should not register this with the bruteforce throttler as it is
actually a valid token. Just expired. Instead the authentication should
fail. And buisness continues as usual.

If your password hash changed (becuse your are on 7.2 and we moved to
ARGON2). Then we shold not 'set a new password' but just update the
hash. As else we invoke the password policy again which might lock out
users.

* On weblogin check if we have invalid public key tokens
* If so update them all with the new token
This ensures that your marked as invalid tokens work again if you once
login on the web.

This protects our cookies a bit more. It makes sure that when a 3rdparty
websites embededs a public alendar for example. That all the users see
this in anonymous mode there.
It adds a small helper function.
In the future we can think about protecting other cookies like this as
well. But for now this is sufficient to not have the user logged in at
all when doing 3rdparty requests.

Due to a misplaced closing parenthesis the condition of the left join
clause was just "userid = uid"; the other conditions were passed as
additional parameters to "leftJoin", and thus they were ignored.
Therefore, the result set contained every preference of each user
instead of only the email, so the "WHERE configvalue LIKE XXX" matched
any configuration value of the user.
Besides the closing parenthesis this commit also fixes the literal
values. Although "Literal" objects represent literal values they must be
created through "IExpressionBuilder::literal()" to be properly quoted;
otherwise it is just a plain string, which is treated as a column name.

* We first try the email as username but this fails
* Then we get the uid from the email and try again
We should not log the first attempt since it polutes the log with failed
login attempts while the login actually is valid.

The CSP nonce is based on the CSRF token. This token does not change,
unless you log in (or out). In case of the session data being lost,
e.g. because php gets rid of old sessions, a new CSRF token is gen-
erated. While this is fine in theory, it actually caused some annoying
problems where the browser restored a tab and Nextcloud js was blocked
due to an outdated nonce.
The main problem here is that, while processing the request, we write
out security headers relatively early. At that point the CSRF token
is known/generated and transformed into a CSP nonce. During this request,
however, we also log the user in because the session information was
lost. At that point we also refresh the CSRF token, which eventually
causes the browser to block any scripts as the nonce in the header
does not match the one which is used to include scripts.
This patch adds a flag to indicate whether the CSRF token should be
refreshed or not. It is assumed that refreshing is only necessary
if we want to re-generate the session id too. To my knowledge, this
case only happens on fresh logins, not when we recover from a deleted
session file.

`\OC\User\Database::createUser` can throw a PHP exception in case the UID is longer than
permitted in the database. This is against it's PHPDocs and we should cast this to `false`,
so that the regular error handling triggers in.
The easiest way to reproduce is on MySQL:
1. Create user `aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa` in admin panel
2. Create user `aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa` in admin panel again
3. See SQL exception as error message

Most of the time, when people have multiple backends or add a
custom backend, they want to create the users there and not in
the default backend. But since that is registered first, users
were always created there.

The encryption app relies on the post_login hook to initialize its keys.
Since we do not emit it on a remembered login, the keys were always un-
initialized and the user was asked to log out and in again.
This patch *translates* the postRememberedLogin hook to a post_login
hook.
