Do not update PRs based on events that happened before they existed
* Split TestPullRequest out of AddTestPullRequestTask
* A Created field is added to the Issue table
* The Created field is set to the time (with nano resolution) on creation
* Record the nano time repo_module.PushUpdateOptions is created by the hook
* The decision to update a pull request created before a commit was
  pushed is based on the time (with nano resolution) the git hook
  was run and the Created field

It ensures the following happens:

* commit C is pushed
* the git hook queues AddTestPullRequestTask for processing and returns with success
* TestPullRequest is not called yet
* a pull request P with commit C as the head is created
* TestPullRequest runs and ignores P because it was created after the commit was received

When the "created" column is NULL, no verification is done, pull
requests that were created before the column was created in the
database cannot be newer than the latest call to a git hook.

Revert "avoid superfluous synchronized pull_request run when opening a PR"
The fix against the race incorrectly assumes the sha of the commit being
pushed belongs to the base repository. It finds the highest possible
pull request ID from the head repository instead of looking it up in
the base repository.

Figuring out if a PR was created in the future based on the highest
index of the base repository would require collecting all of them
because there is no way to know in advance which repository may be
involved in the race.

Fixing this race can be done either by:

* Introducing a new field in the pull_request table https://codeberg.org/forgejo/forgejo/pulls/2842
  which feels more like a hack than a real solution
* Refactoring the logic
  which would be a significant undertaking

The race has been in the codebase for a very long time and manifests
itself in the CI, when events happen in quick succession. The only
concrete manifestation was however fixed by https://codeberg.org/forgejo/forgejo/issues/2009

Since this race now only exists in theory and not in practice, let's
revert this bugous commit until a proper solution is implemented.

[GITEA] avoid superfluous synchronized pull_request run when opening a PR (#2236)
* Split TestPullRequest out of AddTestPullRequestTask
* Before scheduling the task, AddTestPullRequestTask stores the max
  index of the repository
* When the task runs, it does not take into account pull requests that
  have an index higher than the recorded max index

When AddTestPullRequestTask is called with isSync == true, it is the
direct consequence of a new commit being pushed. Forgejo knows nothing
of this new commit yet. If a PR is created later and its head
references the new commit, it will have an index that is higher and
must not be taken into account. It would be acting and triggering a
notification for a PR based on an event that happened before it
existed.

Allow detect whether it's in a database transaction for a context.Context (#21756)
Fix #19513

This PR introduce a new db method `InTransaction(context.Context)`,
and also builtin check on `db.TxContext` and `db.WithTx`.
There is also a new method `db.AutoTx` has been introduced but could be used by other PRs.

`WithTx` will always open a new transaction, if a transaction exist in context, return an error.
`AutoTx` will try to open a new transaction if no transaction exist in context.
That means it will always enter a transaction if there is no error.

Refactor GetNextResourceIndex to make it work properly with transaction (#21469)
Related:
* #21362

This PR uses a general and stable method to generate resource index (eg:
Issue Index, PR Index)

If the code looks good, I can add more tests

ps: please skip the diff, only have a look at the new code. It's
entirely re-written.
