Do not try to create a new authorization grant when one exists already,
thus preventing a DB-related authorization issue.

This commit forces the resource owner (user) to always approve OAuth 2.0
authorization requests if the client is public (e.g. native
applications).
As detailed in [RFC 6749 Section 10.2](https://www.rfc-editor.org/rfc/rfc6749.html#section-10.2),
> The authorization server SHOULD NOT process repeated authorization
requests automatically (without active resource owner interaction)
without authenticating the client or relying on other measures to ensure
that the repeated request comes from the original client and not an
impersonator.
With the implementation prior to this patch, attackers with access to
the redirect URI (e.g., the loopback interface for
`git-credential-oauth`) can get access to the user account without any
user interaction if they can redirect the user to the
`/login/oauth/authorize` endpoint somehow (e.g., with `xdg-open` on
Linux).
Fixes #25061.

A remote user (UserTypeRemoteUser) is a placeholder that can be
promoted to a regular user (UserTypeIndividual). It represents users
that exist somewhere else. Although the UserTypeRemoteUser already
exists in Forgejo, it is neither used or documented.
A new login type / source (Remote) is introduced and set to be the login type
of remote users.
Type UserTypeRemoteUser
LogingType Remote
The association between a remote user and its counterpart in another
environment (for instance another forge) is via the OAuth2 login
source:
LoginName set to the unique identifier relative to the login source
LoginSource set to the identifier of the remote source
For instance when migrating from GitLab.com, a user can be created as
if it was authenticated using GitLab.com as an OAuth2 authentication
source.
When a user authenticates to Forejo from the same authentication
source and the identifier match, the remote user is promoted to a
regular user. For instance if 43 is the ID of the GitLab.com OAuth2
login source, 88 is the ID of the Remote loging source, and 48323
is the identifier of the foo user:
Type UserTypeRemoteUser
LogingType Remote
LoginName 48323
LoginSource 88
Email (empty)
Name foo
Will be promoted to the following when the user foo authenticates to
the Forgejo instance using GitLab.com as an OAuth2 provider. All users
with a LoginType of Remote and a LoginName of 48323 are examined. If
the LoginSource has a provider name that matches the provider name of
GitLab.com (usually just "gitlab"), it is a match and can be promoted.
The email is obtained via the OAuth2 provider and the user set to:
Type UserTypeIndividual
LogingType OAuth2
LoginName 48323
LoginSource 43
Email foo@example.com
Name foo
Note: the Remote login source is an indirection to the actual login
source, i.e. the provider string my be set to a login source that does
not exist yet.
`log.Xxx("%v")` is not ideal, this PR adds necessary context messages.
Remove some unnecessary logs.

During registration, one may be required to give their email address, to
be verified and activated later. However, if one makes a mistake, a
typo, they may end up with an account that cannot be activated due to
having a wrong email address.
They can still log in, but not change the email address, thus, no way to
activate it without help from an administrator.
To remedy this issue, lets allow changing the email address for logged
in, but not activated users.
This fixes gitea#17785.

[GITEA] Allow changing the email address before activation (squash) cache is always active
This needs to be revisited because the MailResendLimit is not enforced
and turns out to not be tested.
See e7cb8da2a8 * Always enable caches (#28527)
(cherry picked from commit 43ded8ee30ab5c7a40a456600cdaa8a0fbdccec2)
Rate limit pre-activation email change separately
Changing the email address before any email address is activated should
be subject to a different rate limit than the normal activation email
resending. If there's only one rate limit for both, then if a newly
signed up quickly discovers they gave a wrong email address, they'd have
to wait three minutes to change it.
With the two separate limits, they don't - but they'll have to wait
three minutes before they can change the email address again.
The downside of this setup is that a malicious actor can alternate
between resending and changing the email address (to something like
`user+$idx@domain`, delivered to the same inbox) to effectively halving
the rate limit. I do not think there's a better solution, and this feels
like such a small attack surface that I'd deem it acceptable.
The way the code works after this change is that `ActivatePost` will now
check the `MailChangeLimit_user` key rather than `MailResendLimit_user`,
and if we're within the limit, it will set `MailChangedJustNow_user`. The
`Activate` method - which sends the activation email, whether it is a
normal resend, or one following an email change - will check
`MailChangedJustNow_user`, and if it is set, it will check the rate
limit against `MailChangedLimit_user`, otherwise against
`MailResendLimit_user`, and then will delete the
`MailChangedJustNow_user` key from the cache.
Fixes #2040.

- This is a 'front-port' of the already existing patch on v1.21 and
v1.20, but applied on top of what Gitea has done to rework the LTA
mechanism. Forgejo will stick with the reworked mechanism by the Forgejo
Security team for the time being. The removal of legacy code (AES-GCM) has been
left out.
- The current architecture is inherently insecure, because you can
construct the 'secret' cookie value with values that are available in
the database. Thus provides zero protection when a database is
dumped/leaked.
- This patch implements a new architecture that's inspired from: [Paragonie Initiative](https://paragonie.com/blog/2015/04/secure-authentication-php-with-long-term-persistence#secure-remember-me-cookies).
- Integration testing is added to ensure the new mechanism works.
- Removes a setting, because it's not used anymore.

Fixes #28660
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.
Nowadays, cache will be used on almost everywhere of Gitea and it cannot
be disabled, otherwise some features will become unaviable.
Then I think we can just remove the option for cache enable. That means
cache cannot be disabled.
But of course, we can still use cache configuration to set how should
Gitea use the cache.
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.
Closes #27455
> The mechanism responsible for long-term authentication (the 'remember
me' cookie) uses a weak construction technique. It will hash the user's
hashed password and the rands value; it will then call the secure cookie
code, which will encrypt the user's name with the computed hash. If one
were able to dump the database, they could extract those two values to
rebuild that cookie and impersonate a user. That vulnerability exists
from the date the dump was obtained until a user changed their password.
>
> To fix this security issue, the cookie could be created and verified
using a different technique such as the one explained at
https://paragonie.com/blog/2015/04/secure-authentication-php-with-long-term-persistence#secure-remember-me-cookies.
The PR removes the now obsolete setting `COOKIE_USERNAME`.
This PR removed `unittest.MainTest` the second parameter
`TestOptions.GiteaRoot`. Now it detects the root directory by current
working directory.

## Changes
- Forces flashed error to render immediately when forgot password code
is incorrect or has expired.
- Adds a link back to the `forgot_password` page so that the user can
restart the process (in the event that their link has expired)
Before:
* `{{.locale.Tr ...}}`
* `{{$.locale.Tr ...}}`
* `{{$.root.locale.Tr ...}}`
* `{{template "sub" .}}`
* `{{template "sub" (dict "locale" $.locale)}}`
* `{{template "sub" (dict "root" $)}}`
* .....
With context function: only need to `{{ctx.Locale.Tr ...}}`
The "ctx" could be considered as a super-global variable for all
templates including sub-templates.
To avoid potential risks (any bug in the template context function
package), this PR only starts using "ctx" in "head.tmpl" and
"footer.tmpl" and it has a "DataRaceCheck". If there is anything wrong,
the code can be fixed or reverted easily.
The JSONRedirect/JSONOK/JSONError functions were put into "Base" context
incorrectly, it would cause abuse.
Actually, they are for "web context" only, so, move them to the correct
place.
And by the way, use them to simplify old code: +75 -196
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`

The PKCE flow according to [RFC
7636](https://datatracker.ietf.org/doc/html/rfc7636) allows for secure
authorization without the requirement to provide a client secret for the
OAuth app.
It is implemented in Gitea since #5378 (v1.8.0), however without being
able to omit client secret.
Since #21316 Gitea supports setting client type at OAuth app
registration.
As public clients are already forced to use PKCE since #21316, in this
PR the client secret check is being skipped if a public client is
detected. As Gitea seems to implement PKCE authorization correctly
according to the spec, this would allow for PKCE flow without providing
a client secret.
Also add some docs for it, please check language as I'm not a native
English speaker.
Closes #17107
Closes #25047
The "modules/context.go" is too large to maintain.
This PR splits it to separate files, eg: context_request.go,
context_response.go, context_serve.go
This PR will help:
1. The future refactoring for Gitea's web context (eg: simplify the context)
2. Introduce proper "range request" support
3. Introduce context function
This PR only moves code, doesn't change any logic.
This change prevents Gitea from bypassing the manual approval process
for newly registered users when OIDC is used.

Close #24062
At the beginning, I just wanted to fix the warning mentioned by #24062
But, the cookie code really doesn't look good to me, so clean up them.
Complete the TODO on `SetCookie`:
> TODO: Copied from gitea.com/macaron/macaron and should be improved
after macaron removed.
