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. 

Notices:
- Chi router don't support request with trailing slash
- Integration test `TestUserHeatmap` maybe mysql version related. It's failed on my macOS(mysql 5.7.29 installed via brew) but succeed on CI.

CORS net/http middleware

go-chi/cors is a fork of github.com/rs/cors that provides a net/http compatible middleware for performing preflight CORS checks on the server side. These headers are required for using the browser native Fetch API.

This middleware is designed to be used as a top-level middleware on the chi router. Applying with within a r.Group() or using With() will not work without routes matching OPTIONS added.

Usage

func main() {
  r := chi.NewRouter()

  // Basic CORS
  // for more ideas, see: https://developer.github.com/v3/#cross-origin-resource-sharing
  r.Use(cors.Handler(cors.Options{
    // AllowedOrigins: []string{"https://foo.com"}, // Use this to allow specific origin hosts
    AllowedOrigins:   []string{"*"},
    // AllowOriginFunc:  func(r *http.Request, origin string) bool { return true },
    AllowedMethods:   []string{"GET", "POST", "PUT", "DELETE", "OPTIONS"},
    AllowedHeaders:   []string{"Accept", "Authorization", "Content-Type", "X-CSRF-Token"},
    ExposedHeaders:   []string{"Link"},
    AllowCredentials: false,
    MaxAge:           300, // Maximum value not ignored by any of major browsers
  }))

  r.Get("/", func(w http.ResponseWriter, r *http.Request) {
    w.Write([]byte("welcome"))
  })

  http.ListenAndServe(":3000", r)
}
