Add LFS Migration and Mirror (#14726) * Implemented LFS client. * Implemented scanning for pointer files. * Implemented downloading of lfs files. * Moved model-dependent code into services. * Removed models dependency. Added TryReadPointerFromBuffer. * Migrated code from service to module. * Centralised storage creation. * Removed dependency from models. * Moved ContentStore into modules. * Share structs between server and client. * Moved method to services. * Implemented lfs download on clone. * Implemented LFS sync on clone and mirror update. * Added form fields. * Updated templates. * Fixed condition. * Use alternate endpoint. * Added missing methods. * Fixed typo and make linter happy. * Detached pointer parser from gogit dependency. * Fixed TestGetLFSRange test. * Added context to support cancellation. * Use ReadFull to probably read more data. * Removed duplicated code from models. * Moved scan implementation into pointer_scanner_nogogit. * Changed method name. * Added comments. * Added more/specific log/error messages. * Embedded lfs.Pointer into models.LFSMetaObject. * Moved code from models to module. * Moved code from models to module. * Moved code from models to module. * Reduced pointer usage. * Embedded type. * Use promoted fields. * Fixed unexpected eof. * Added unit tests. * Implemented migration of local file paths. * Show an error on invalid LFS endpoints. * Hide settings if not used. * Added LFS info to mirror struct. * Fixed comment. * Check LFS endpoint. * Manage LFS settings from mirror page. * Fixed selector. * Adjusted selector. * Added more tests. * Added local filesystem migration test. * Fixed typo. * Reset settings. * Added special windows path handling. * Added unit test for HTTPClient. * Added unit test for BasicTransferAdapter. * Moved into util package. * Test if LFS endpoint is allowed. * Added support for git:// * Just use a static placeholder as the displayed url may be invalid. * Reverted to original code. * Added "Advanced Settings". * Updated wording. * Added discovery info link. * Implemented suggestion. * Fixed missing format parameter. * Added Pointer.IsValid(). * Always remove model on error. * Added suggestions. * Use channel instead of array. * Update routers/repo/migrate.go * fmt Signed-off-by: Andrew Thornton <art27@cantab.net> Co-authored-by: zeripath <art27@cantab.net>

Move macaron to chi (#14293) Use [chi](https://github.com/go-chi/chi) instead of the forked [macaron](https://gitea.com/macaron/macaron). Since macaron and chi have conflicts with session share, this big PR becomes a have-to thing. According my previous idea, we can replace macaron step by step but I'm wrong. :( Below is a list of big changes on this PR. - [x] Define `context.ResponseWriter` interface with an implementation `context.Response`. - [x] Use chi instead of macaron, and also a customize `Route` to wrap chi so that the router usage is similar as before. - [x] Create different routers for `web`, `api`, `internal` and `install` so that the codes will be more clear and no magic . - [x] Use https://github.com/unrolled/render instead of macaron's internal render - [x] Use https://github.com/NYTimes/gziphandler instead of https://gitea.com/macaron/gzip - [x] Use https://gitea.com/go-chi/session which is a modified version of https://gitea.com/macaron/session and removed `nodb` support since it will not be maintained. **BREAK** - [x] Use https://gitea.com/go-chi/captcha which is a modified version of https://gitea.com/macaron/captcha - [x] Use https://gitea.com/go-chi/cache which is a modified version of https://gitea.com/macaron/cache - [x] Use https://gitea.com/go-chi/binding which is a modified version of https://gitea.com/macaron/binding - [x] Use https://github.com/go-chi/cors instead of https://gitea.com/macaron/cors - [x] Dropped https://gitea.com/macaron/i18n and make a new one in `code.gitea.io/gitea/modules/translation` - [x] Move validation form structs from `code.gitea.io/gitea/modules/auth` to `code.gitea.io/gitea/modules/forms` to avoid dependency cycle. - [x] Removed macaron log service because it's not need any more. **BREAK** - [x] All form structs have to be get by `web.GetForm(ctx)` in the route function but not as a function parameter on routes definition. - [x] Move Git HTTP protocol implementation to use routers directly. - [x] Fix the problem that chi routes don't support trailing slash but macaron did. - [x] `/api/v1/swagger` now will be redirect to `/api/swagger` but not render directly so that `APIContext` will not create a html render.
