Correctly handle select on multiple channels in Queues (#22146) (#22428)
Backport #22146

There are a few places in FlushQueueWithContext which make an incorrect
assumption about how `select` on multiple channels works.

The problem is best expressed by looking at the following example:

```go
package main

import "fmt"

func main() {
    closedChan := make(chan struct{})
    close(closedChan)
    toClose := make(chan struct{})
    count := 0

    for {
        select {
        case <-closedChan:
            count++
            fmt.Println(count)
            if count == 2 {
                close(toClose)
            }
        case <-toClose:
            return
        }
    }
}
```

This PR double-checks that the contexts are closed outside of checking
if there is data in the dataChan. It also rationalises the WorkerPool
FlushWithContext because the previous implementation failed to handle
pausing correctly. This will probably fix the underlying problem in
 #22145

Fix sitemap (#22272) (#22320)
Backport #22272.

Fix #22270.

Related to #18407.

The old code treated both sitemap and sitemap index as the format like:

```xml
...
<url>
  <loc>http://localhost:3000/explore/users/sitemap-1.xml</loc>
</url>
...
```

Actually, it's incorrect for sitemap index, it should be:

```xml
...
<sitemap>
  <loc>http://localhost:3000/explore/users/sitemap-1.xml</loc>
</sitemap>
...
```

Add more test directory to exclude dir of air, remove watching templates from air include dir because gitea has internal mechanism (#22246) (#22247)
backport #22246 

Since #20218 introduced internal watching template, template watching
should be removed from `air`. This will prevent restart the whole server
once the template files changed to speed up developing when using `make
watch`.

To ensure `make watch` will reuse template watching, this PR introduced
a new ENV `GITEA_RUN_MODE` to make sure `make watch` will always run in
a dev mode of Gitea so that template watching will open.

This PR also added more exclude testdata directories.

refactor auth interface to return error when verify failure (#22119) (#22259)
backport #22119

This PR changed the Auth interface signature from `Verify(http
*http.Request, w http.ResponseWriter, store DataStore, sess
SessionStore) *user_model.User`
to 
`Verify(http *http.Request, w http.ResponseWriter, store DataStore, sess
SessionStore) (*user_model.User, error)`.

There is a new return argument `error` which means the verification
condition matched but verify process failed, we should stop the auth
process.

Before this PR, when return a `nil` user, we don't know the reason why
it returned `nil`. If the match condition is not satisfied or it
verified failure? For these two different results, we should have
different handler. If the match condition is not satisfied, we should
try next auth method and if there is no more auth method, it's an
anonymous user. If the condition matched but verify failed, the auth
process should be stop and return immediately.

This will fix #20563

Add setting to disable the git apply step in test patch (#22130) (#22170)
Backport #22130

For a long time Gitea has tested PR patches using a git apply --check
method, and in fact prior to the introduction of a read-tree assisted
three-way merge in #18004, this was the only way of checking patches.

Since #18004, the git apply --check method has been a fallback method,
only used when the read-tree three-way merge method has detected a
conflict. The read-tree assisted three-way merge method is much faster
and less resource intensive method of detecting conflicts. #18004 kept
the git apply method around because it was thought possible that this
fallback might be able to rectify conflicts that the read-tree three-way
merge detected. I am not certain if this could ever be the case.

Given the uncertainty here and the now relative stability of the
read-tree method - this PR makes using this fallback optional but
enables it by default. A `log.Critical` has been added which will alert
if the `git apply --check` method was successful at checking a PR that
`read-tree` failed on.

The hope is that none of these log.Critical messages will be found and
there will be no significant difference in conflict detection. Thus we
will be able to remove the git apply fallback in future, and/or improve
the read-tree three-way merge method to catch any conflicts that git
apply method might have been able to fix.

An additional benefit for anyone who disables the check method is that
patch checking should be significantly less resource intensive and much
quicker.

Ensure that plain files are rendered correctly even when containing ambiguous characters (#22017) (#22160)
Backport #22017

As recognised in #21841 the rendering of plain text files is somewhat
incorrect when there are ambiguous characters as the html code is double
escaped. In fact there are several more problems here.

We have a residual isRenderedHTML which is actually simply escaping the
file - not rendering it. This is badly named and gives the wrong
impression.

There is also unusual behaviour whether the file is called a Readme or
not and there is no way to get to the source code if the file is called
README.

In reality what should happen is different depending on whether the file
is being rendered a README at the bottom of the directory view or not.

1. If it is rendered as a README on a directory - it should simply be
escaped and rendered as `<pre>` text.
2. If it is rendered as a file then it should be rendered as source
code.

This PR therefore does:
1. Rename IsRenderedHTML to IsPlainText
2. Readme files rendered at the bottom of the directory are rendered
without line numbers
3. Otherwise plain text files are rendered as source code.

Replace #21841

Backport #21945

Unfortunately the fallback configuration code for [mailer] that were
added in #18982 are incorrect. When you read a value from an ini section
that key is added. This leads to a failure of the fallback mechanism.
Further there is also a spelling mistake in the startTLS configuration.

This PR restructures the mailer code to first map the deprecated
settings on to the new ones - and then use ini.MapTo to map those on to
the struct with additional validation as necessary.

Prevent panic in doctor command when running default checks (#21791) (#21807)
Backport #21791

There was a bug introduced in #21352 due to a change of behaviour caused
by #19280. This causes a panic on running the default doctor checks
because the panic introduced by #19280 assumes that the only way
opts.StdOut and opts.Stderr can be set in RunOpts is deliberately.
Unfortunately, when running a git.Command the provided RunOpts can be
set, therefore if you share a common set of RunOpts these two values can
be set by the previous commands.

This PR stops using common RunOpts for the commands in that doctor check
but secondly stops RunCommand variants from changing the provided
RunOpts.

> Authorization servers SHOULD reject authorization requests from native
apps that don't use PKCE by returning an error message

Fixes #21299

Refactor git command arguments and make all arguments to be safe to be used (#21535)
Follow #21464

Make all git command arguments strictly safe. Most changes are one-to-one replacing, keep all existing logic.

Add link to user profile in markdown mention only if user exists (#21533)
Previously mentioning a user would link to its profile, regardless of
whether the user existed. This change tests if the user exists and only
if it does - a link to its profile is added.

* Fixes #3444

Decouple HookTask from Repository (#17940)
At the moment a repository reference is needed for webhooks. With the
upcoming package PR we need to send webhooks without a repository
reference. For example a package is uploaded to an organization. In
theory this enables the usage of webhooks for future user actions.

This PR removes the repository id from `HookTask` and changes how the
hooks are processed (see `services/webhook/deliver.go`). In a follow up
PR I want to remove the usage of the `UniqueQueue´ and replace it with a
normal queue because there is no reason to be unique.

Make every not exist error unwrappable to a fs.ErrNotExist (#20891)
A lot of our code is repeatedly testing if individual errors are
specific types of Not Exist errors. This is repetitative and unnecesary.
`Unwrap() error` provides a common way of labelling an error as a
NotExist error and we can/should use this.

This PR has chosen to use the common `io/fs` errors e.g.
`fs.ErrNotExist` for our errors. This is in some ways not completely
correct as these are not filesystem errors but it seems like a
reasonable thing to do and would allow us to simplify a lot of our code
to `errors.Is(err, fs.ErrNotExist)` instead of
`package.IsErr...NotExist(err)`

I am open to suggestions to use a different base error - perhaps
`models/db.ErrNotExist` if that would be felt to be better.
