This allows `nix flake metadata` and nix in general to lock a *branch*
tarball link in a manner that causes it to fetch the correct commit even
if the branch is updated with a newer version.
For further context, Nix flakes are a feature that, among other things,
allows for "inputs" that are "github:someuser/somerepo",
"https://some-tarball-service/some-tarball.tar.gz",
"sourcehut:~meow/nya" or similar. This feature allows our users to fetch
tarballs of git-based inputs to their builds rather than using git to
fetch them, saving significant download time.
There is presently no gitea or forgejo specific fetcher in Nix, and we
don't particularly wish to have one. Ideally (as a developer on a Nix
implementation myself) we could just use the generic tarball fetcher and
not add specific forgejo support, but to do so, we need additional
metadata to know which commit a given *branch* tarball represents, which
is the purpose of the Link header added here.
The result of this patch is that a Nix user can specify `inputs.something.url =
"https://forgejo-host/some/project/archive/main.tar.gz"` in flake.nix
and get a link to some concrete tarball for the actual commit in the
lock file, then when they run `nix flake update` in the future, they
will get the latest commit in that branch.
Example of it working locally:
» nix flake metadata --refresh 'http://localhost:3000/api/v1/repos/jade/cats/archive/main.tar.gz?dir=configs/nix'
Resolved URL: http://localhost:3000/api/v1/repos/jade/cats/archive/main.tar.gz?dir=configs/nix

In `repo.RemoveDependency`, use `PostFormValue` instead of
`PostForm.Get`. The latter requires `ParseForm()` to be called prior,
and in this case, has no benefit over `PostFormValue` anyway (which
calls `ParseForm()` if necessary).
While this currently does not cause any issue as far as I can tell, it
feels like a bug lying in wait for the perfect opportunity. Lets squash
it before it can do harm.

Adjust the `anyHashPattern` to match URL query parameters too, and
adjust `fullHashPatternProcessor` accordingly.
Includes a test case, and an update to an existing one to account for
the new capture group.
Fixes#3548.

Also add a test for GogsDownloaderFactory.New() to make sure
that the URL of the source repository is parsed correctly.
When the source gogs instance is hosted at a subpath like `https://git.example.com/gogs/<username>/<reponame>` the migration fails.
This PR fixes that.

To be able to easily test cases where the repository does not have any
code, where the git repo itself is completely uninitialized, lets
support a case where the `AutoInit` property is false.
For the sake of backwards compatibility, if the option is not set either
way, it will default to `true`.

When subscribing or unsubscribing to/from an issue on the web ui, the
request was posted to a route handled by `repo.IssueWatch`. This
function used `ctx.Req.PostForm.Get()`, erroneously.
`request.PostForm` is *only* available if `request.ParseForm()` has been
called before it. The function in question did not do that. Under some
circumstances, something, somewhere did end up calling `ParseForm()`,
but not in every scenario.
Since we do not need to check for multiple values, the easiest fix here
is to use `ctx.Req.PostFormValue`, which will call `ParseForm()` if
necessary.
Fixes#3516.

If `commitstatus_service.FindReposLastestCommitStatuses` receives no
repos in its params, short-circuit, and return early, without performing
any potentially expensive work.

When a logged in user with no repositories visits their dashboard, it will
display a search box that lists their own repositories.
This is served by the `repo.SearchRepos` handler, which in turn calls
`commitstatus_service.FindReposLastestCommitStatuses()` with an empty
repo list.
That, in turn, will call `git_model.FindBranchesByRepoAndBranchName()`,
with an empty map. With no map, `FindBranchesByRepoAndBranchName()` ends
up querying the entire `branch` table, because no conditions were set
up.
Armed with a gazillion repo & commit shas, we return to
`FindReposLastestCommitStatuses`, and promptly call
`git_model.GetLatestCommitStatusForPairs`, which constructs a monstrous
query with so many placeholders that the database tells us to go
somewhere else, and flips us off. At least on instances the size of
Codeberg. On smaller instances, it will eventually return, and throw
away all the data, and return an empty set, having performed all this
for naught.
We fix this by short-circuiting `FindBranchesByRepoAndBranchName`, and
returning fast if our inputs are empty.
A test case is included.
Fixes#3521.
