Manually tested this by:
- Following the
[installation](https://docs.gitea.com/next/installation/install-with-docker#basics)
guide (but built a local Docker image instead)
- Creating 2 users, one who is the `Owner` of a newly-created repository
and the other a `Collaborator`
- Had the `Collaborator` create a PR that the `Owner` reviews
- `Collaborator` resolves conversation and `Owner` merges PR

And with this change we see that we can no longer see re-request review
button for the `Owner`:

Fix #20175

Current implementation of API does not allow creating pull requests
between branches of the same
repo when you specify *namespace* (owner of the repo) in `head` field in
http request body.

--- 

Although GitHub implementation of API allows performing such action and
since Gitea targeting
compatibility with GitHub API I see it as an appropriate change.

I'm proposing a fix to the described problem and test case which covers
this logic.

After repository commit status has been introduced on dashaboard, the
most top SQL comes from `GetLatestCommitStatusForPairs`.

This PR adds a cache for the repository's default branch's latest
combined commit status. When a new commit status updated, the cache will
be marked as invalid.

Since `modules/context` has to depend on `models` and many other

`services/context` according to design principles. There is no logic
code change on this PR, only move packages.

`code.gitea.io/gitea/services/context`
- Move `code.gitea.io/gitea/modules/contexttest` to

When we update an lfs file by API
`api/v1/repos/{owner}/{repo}/contents/{filepath}`, there will show an
error

```json
{
  "message": "Put \"05904d6c7b16bb9b29587100ab1414\": readfrom tcp [::1]:57300->[::1]:9000: content size does not match",
  "url": "http://localhost:3000/api/swagger"
}
```

The reason of this error is
https://github.com/go-gitea/gitea/blob/main/services/repository/files/update.go,
in this file, the `file.ContentReader` been used twice. So when use
`file.ContentReader` in the second time, the `i` of this Reader has been
updated to the length of the content. it will return 0 and an `io.EOF`
error when we try to read cotent from this Reader.

Clarify when "string" should be used (and be escaped), and when
"template.HTML" should be used (no need to escape)

And help PRs like  #29059 , to render the error messages correctly.

With this option, it is possible to require a linear commit history with
the following benefits over the next best option `Rebase+fast-forward`:
The original commits continue existing, with the original signatures
continuing to stay valid instead of being rewritten, there is no merge
commit, and reverting commits becomes easier.

Closes #24906

The old code `GetTemplatesFromDefaultBranch(...) ([]*api.IssueTemplate,
map[string]error)` doesn't really follow Golang's habits, then the
second returned value might be misused. For example, the API function
`GetIssueTemplates` incorrectly checked the second returned value and
always responds 500 error.

This PR refactors GetTemplatesFromDefaultBranch to
ParseTemplatesFromDefaultBranch and clarifies its behavior, and fixes the
API endpoint bug, and adds some tests.

And by the way, add proper prefix `X-` for the header generated in
`checkDeprecatedAuthMethods`, because non-standard HTTP headers should
have `X-` prefix, and it is also consistent with the new code in
`GetIssueTemplates`

In #28691, schedule plans will be deleted when a repo's actions unit is
disabled. But when the unit is enabled, the schedule plans won't be
created again.

This PR fixes the bug. The schedule plans will be created again when the
actions unit is re-enabled

## Purpose
This is a refactor toward building an abstraction over managing git
repositories.
Afterwards, it does not matter anymore if they are stored on the local
disk or somewhere remote.

## What this PR changes
We used `git.OpenRepository` everywhere previously.
Now, we should split them into two distinct functions:

Firstly, there are temporary repositories which do not change:

```go
git.OpenRepository(ctx, diskPath)
```

Gitea managed repositories having a record in the database in the
`repository` table are moved into the new package `gitrepo`:

```go
gitrepo.OpenRepository(ctx, repo_model.Repo)
```

Why is `repo_model.Repository` the second parameter instead of file
path?
Because then we can easily adapt our repository storage strategy.
The repositories can be stored locally, however, they could just as well
be stored on a remote server.

## Further changes in other PRs
- A Git Command wrapper on package `gitrepo` could be created. i.e.
`NewCommand(ctx, repo_model.Repository, commands...)`. `git.RunOpts{Dir:
repo.RepoPath()}`, the directory should be empty before invoking this
method and it can be filled in the function only. #28940
- Remove the `RepoPath()`/`WikiPath()` functions to reduce the
possibility of mistakes.

Currently, the `updateMirror` function which update the mirror interval
and enable prune properties is only executed by the `Edit` function. But
it is only triggered if `opts.MirrorInterval` is not null, even if
`opts.EnablePrune` is not null.

With this patch, it is now possible to update the enable_prune property
with a patch request without modifying the mirror_interval.

## Example request with httpie

### Currently:
**Does nothing**
```bash
http PATCH https://gitea.your-server/api/v1/repos/myOrg/myRepo "enable_prune:=false" -A bearer -a $gitea_token
```

**Updates both properties**
```bash
http PATCH https://gitea.your-server/api/v1/repos/myOrg/myRepo "enable_prune:=false" "mirror_interval=10m" -A bearer -a $gitea_token
```

### With the patch
**Updates enable_prune only**
```bash
http PATCH https://gitea.your-server/api/v1/repos/myOrg/myRepo "enable_prune:=false" -A bearer -a $gitea_token
```

Currently only SHA1 repositories are supported by Gitea. This adds
support for alternate SHA256 with the additional aim of easier support
for additional hash types in the future.

Sometimes you need to work on a feature which depends on another (unmerged) feature.
In this case, you may create a PR based on that feature instead of the main branch.
Currently, such PRs will be closed without the possibility to reopen in case the parent feature is merged and its branch is deleted.
Automatic target branch change make life a lot easier in such cases.
Github and Bitbucket behave in such way.

Example:
$PR_1$: main <- feature1
$PR_2$: feature1 <- feature2

Currently, merging $PR_1$ and deleting its branch leads to $PR_2$ being closed without the possibility to reopen.
This is both annoying and loses the review history when you open a new PR.

With this change, $PR_2$ will change its target branch to main ($PR_2$: main <- feature2) after $PR_1$ has been merged and its branch has been deleted.

This behavior is enabled by default but can be disabled.
For security reasons, this target branch change will not be executed when merging PRs targeting another repo.

Fixes #28764.

Fixes #27114.

* In Gitea 1.12 (#9532), a "dismiss stale approvals" branch protection
setting was introduced, for ignoring stale reviews when verifying the
approval count of a pull request.
* In Gitea 1.14 (#12674), the "dismiss review" feature was added.
* This caused confusion with users (#25858), as "dismiss" now means 2
different things.
* In Gitea 1.20 (#25882), the behavior of the "dismiss stale approvals"
branch protection was modified to actually dismiss the stale review.

For some users this new behavior of dismissing the stale reviews is not
desirable.

So this PR reintroduces the old behavior as a new "ignore stale
approvals" branch protection setting.

Fix #28157 

This PR fix the possible bugs about actions schedule.

## The Changes

- Move `UpdateRepositoryUnit` and `SetRepoDefaultBranch` from models to
service layer
- Remove schedules plan from database and cancel waiting & running
schedules tasks in this repository when actions unit has been disabled
or global disabled.
- Remove schedules plan from database and cancel waiting & running
schedules tasks in this repository when default branch changed.

Fix #27722 
Fix #27357
Fix #25837 
1. Fix the typo `BlockingByDependenciesNotPermitted`, which causes the
`not permitted message` not to show. The correct one is `Blocking` or
`BlockedBy`
2. Rewrite the perm check. The perm check uses a very tricky way to
avoid duplicate checks for a slice of issues, which is confusing. In
fact, it's also the reason causing the bug. It uses `lastRepoID` and
`lastPerm` to avoid duplicate checks, but forgets to assign the
`lastPerm` at the end of the code block. So I rewrote this to avoid this
trick.

3. It also reuses the `blocks` slice, which is even more confusing. So I
rewrote this too.

Introduce the new generic deletion methods
- `func DeleteByID[T any](ctx context.Context, id int64) (int64, error)`
- `func DeleteByIDs[T any](ctx context.Context, ids ...int64) error`
- `func Delete[T any](ctx context.Context, opts FindOptions) (int64,

So, we no longer need any specific deletion method and can just use
the generic ones instead.

- Store `ObjectFormatName` in `repository` struct

Refactor Hash interfaces and centralize hash function. This will allow
easier introduction of different hash function later on.

This forms the "no-op" part of the SHA256 enablement patch.

Continue of #27798 and move more functions to `db.Find` and `db.Count`.

Fix #28056 

This PR will check whether the repo has zero branch when pushing a
branch. If that, it means this repository hasn't been synced.

The reason caused that is after user upgrade from v1.20 -> v1.21, he
just push branches without visit the repository user interface. Because
all repositories routers will check whether a branches sync is necessary
but push has not such check.

For every repository, it has two states, synced or not synced. If there
is zero branch for a repository, then it will be assumed as non-sync
state. Otherwise, it's synced state. So if we think it's synced, we just
need to update branch/insert new branch. Otherwise do a full sync. So
that, for every push, there will be almost no extra load added. It's
high performance than yours.

For the implementation, we in fact will try to update the branch first,
if updated success with affect records > 0, then all are done. Because
that means the branch has been in the database. If no record is
affected, that means the branch does not exist in database. So there are
two possibilities. One is this is a new branch, then we just need to
insert the record. Another is the branches haven't been synced, then we
need to sync all the branches into database.
