This will allow instance admins to view signup pattern patterns for
public instances. It is modelled after discourse, mastodon, and
MediaWiki's approaches.
Note: This has privacy implications, but as the above-stated open-source
projects take this approach, especially MediaWiki, which I have no doubt
looked into this thoroughly, it is likely okay for us, too. However, I
would be appreciative of any feedback on how this could be improved.

This leverages the existing `sync_external_users` cron job to
synchronize the `IsActive` flag on users who use an OAuth2 provider set
to synchronize. This synchronization is done by checking for expired
access tokens, and using the stored refresh token to request a new
access token. If the response back from the OAuth2 provider is the
`invalid_grant` error code, the user is marked as inactive. However, the
user is able to reactivate their account by logging in the web browser
through their OAuth2 flow.
Also changed to support this is that a linked `ExternalLoginUser` is
always created upon a login or signup via OAuth2.
### Notes on updating permissions
Ideally, we would also refresh permissions from the configured OAuth
provider (e.g., admin, restricted and group mappings) to match the
implementation of LDAP. However, the OAuth library used for this `goth`,
doesn't seem to support issuing a session via refresh tokens. The
interface provides a [`RefreshToken`
method](https://github.com/markbates/goth/blob/master/provider.go#L20),
but the returned `oauth.Token` doesn't implement the `goth.Session` we
would need to call `FetchUser`. Due to specific implementations, we
would need to build a compatibility function for every provider, since
they cast to concrete types (e.g.
[Azure](https://github.com/markbates/goth/blob/master/providers/azureadv2/azureadv2.go#L132))

Noteable additions:
- `redefines-builtin-id` forbid variable names that shadow go builtins
- `empty-lines` remove unnecessary empty lines that `gofumpt` does not
remove for some reason
- `superfluous-else` eliminate more superfluous `else` branches
Rules are also sorted alphabetically and I cleaned up various parts of
`.golangci.yml`.
Cookies may exist on "/subpath" and "/subpath/" for some legacy reasons (eg: changed CookiePath behavior in code). The legacy cookie should be removed correctly.

Old code is not consistent for generating & decoding the JWT secrets.
Now, the callers only need to use 2 consistent functions:
NewJwtSecretWithBase64 and DecodeJwtSecretBase64
And remove a non-common function Base64FixedDecode from util.go

Fixes an admin api bug related to `user.LoginSource`
Fixed `/user/emails` response not identical to GitHub api
This PR unifies the user update methods. The goal is to keep the logic
only at one place (having audit logs in mind). For example, do the
password checks only in one method not everywhere a password is updated.
After that PR is merged, the user creation should be next.
The steps to reproduce it.
First, create a new oauth2 source.
Then, a user login with this oauth2 source.
Disable the oauth2 source.
Visit users -> settings -> security, 500 will be displayed.
This is because this page only load active Oauth2 sources but not all
Oauth2 sources.
When the user does not set a username lookup condition, LDAP will get an
empty string `""` for the user, hence the following code
```
if isExist, err := user_model.IsUserExist(db.DefaultContext, 0, sr.Username)
```
The user presence determination will always be nonexistent, so updates
to user information will never be performed.
Fix#27049
Part of #27065
This reduces the usage of `db.DefaultContext`. I think I've got enough
files for the first PR. When this is merged, I will continue working on
this.
Considering how many files this PR affect, I hope it won't take to long
to merge, so I don't end up in the merge conflict hell.

Bumping `github.com/golang-jwt/jwt` from v4 to v5.
`github.com/golang-jwt/jwt` v5 is bringing some breaking changes:
- standard `Valid()` method on claims is removed. It's replaced by
`ClaimsValidator` interface implementing `Validator()` method instead,
which is called after standard validation. Gitea doesn't seem to be
using this logic.
- `jwt.Token` has a field `Valid`, so it's checked in `ParseToken`
function in `services/auth/source/oauth2/token.go`

Fix#21072
Username Attribute is not a required item when creating an
authentication source. If Username Attribute is empty, the username
value of LDAP user cannot be read, so all users from LDAP will be marked
as inactive by mistake when synchronizing external users.
This PR improves the sync logic, if username is empty, the email address
will be used to find user.
The plan is that all built-in auth providers use inline SVG for more
flexibility in styling and to get the GitHub icon to follow
`currentcolor`. This only removes the `public/img/auth` directory and
adds the missing svgs to our svg build.
It should map the built-in providers to these SVGs and render them. If
the user has set a Icon URL, it should render that as an `img` tag
instead.

"registration success email" is only used for notifying a user that "you
have a new account now" when the account is created by admin manually.
When a user uses external auth source, they already knows that they has
the account, so do not send such email.

Since the login form label for user_name unconditionally displays
`Username or Email Address` for the `user_name` field, bring matching
LDAP filters to more prominence in the documentation/placeholders.

This allows for usernames, and emails connected to them to be reserved
and not reused.
Use case, I manage an instance with open registration, and sometimes
when users are deleted for spam (or other purposes), their usernames are
freed up and they sign up again with the same information.
This could also be used to reserve usernames, and block them from being
registered (in case an instance would like to block certain things
without hardcoding the list in code and compiling from scratch).
This is an MVP, that will allow for future work where you can set
something as reserved via the interface.

In the `for` loop, the value of `membershipsToAdd[org]` and
`membershipsToRemove[org]` is a slice that should be appended instead of
overwritten.
Due to the current overwrite, the LDAP group sync only matches the last
group at the moment.
## Example reproduction
- an LDAP user is both a member of
`cn=admin_staff,ou=people,dc=planetexpress,dc=com` and
`cn=ship_crew,ou=people,dc=planetexpress,dc=com`.
- configuration of `Map LDAP groups to Organization teams ` in
`Authentication Sources`:
```json
{
"cn=admin_staff,ou=people,dc=planetexpress,dc=com":{
"test_organization":[
"admin_staff",
"test_add"
]
},
"cn=ship_crew,ou=people,dc=planetexpress,dc=com":{
"test_organization":[
"ship_crew"
]
}
```
- start `Synchronize external user data` task in the `Dashboard`.
- the user was only added for the team `test_organization.ship_crew`
When running listLdapGroupMemberships check if the groupFilter is empty
before using it to list memberships.

It provides a drop-in replacement for crypto/sha256 and if the

This PR implements the mapping of user groups provided by OIDC providers
to orgs teams in Gitea. The main part is a refactoring of the existing
LDAP code to make it usable from different providers.
Refactorings:
- Moved the router auth code from module to service because of import
cycles
- Changed some model methods to take a `Context` parameter
- Moved the mapping code from LDAP to a common location
I've tested it with Keycloak but other providers should work too. The
JSON mapping format is the same as for LDAP.

There are 2 separate flows of creating a user: authentication and source
sync.
When a group filter is defined, source sync ignores group filter, while
authentication respects it.
With this PR I've fixed this behavior, so both flows now apply this
filter when searching users in LDAP in a unified way.
- Unified LDAP group membership lookup for authentication and source
sync flows
- Replaced custom group membership lookup (used for authentication flow)
with an existing listLdapGroupMemberships method (used for source sync
flow)
- Modified listLdapGroupMemberships and getUserAttributeListedInGroup in
a way group lookup could be called separately
- Added user filtering based on a group membership for a source sync
- Added tests to cover this logic

- Move the file `compare.go` and `slice.go` to `slice.go`.
- Fix `ExistsInSlice`, it's buggy
- It uses `sort.Search`, so it assumes that the input slice is sorted.
- It passes `func(i int) bool { return slice[i] == target })` to
`sort.Search`, that's incorrect, check the doc of `sort.Search`.
- Conbine `IsInt64InSlice(int64, []int64)` and `ExistsInSlice(string,
[]string)` to `SliceContains[T]([]T, T)`.
- Conbine `IsSliceInt64Eq([]int64, []int64)` and `IsEqualSlice([]string,
[]string)` to `SliceSortedEqual[T]([]T, T)`.
- Add `SliceEqual[T]([]T, T)` as a distinction from
`SliceSortedEqual[T]([]T, T)`.
- Redesign `RemoveIDFromList([]int64, int64) ([]int64, bool)` to
`SliceRemoveAll[T]([]T, T) []T`.
- Add `SliceContainsFunc[T]([]T, func(T) bool)` and
`SliceRemoveAllFunc[T]([]T, func(T) bool)` for general use.
- Add comments to explain why not `golang.org/x/exp/slices`.
- Add unit tests.
