- moved gitgraph.js to web_src and made it importable and es6-compatible
- created new webpack chunk for gitgraph
- enabled CSS loader in webpack
- enabled async/await syntax via regenerator-runtime
- added script to ensure webpack chunks are loaded correctly
- disable terser's comment extraction to prevent .LICENCE files
gitgraph.js has many issues:
1. it is incompatible with ES6 because of strict-mode violations
1. it does not export anything
1. it's css has weird styles like for `body`
1. it is not available on npm
I fixed points 1-3 in our version so it's now loadable in webpack. We should eventually consider alternatives.

Fix#8718
This PR shadows passwords in session config correctly by detecting
the VirtualProvider, unmarshalling the original config and then
shadowing config within that.
In investigating #7947 it has become clear that the storage component of go-git repositories needs closing.
This PR adds this Close function and adds the Close functions as necessary.
In TransferOwnership the ctx.Repo.GitRepo is closed if it is open to help prevent the risk of multiple open files.
Fixes#7947
There are two major components to this PR:
* This PR handles merge and rebase failures from merging a little more nicely with Flash errors rather a 500.
* All git commands are run in the LC_ALL="C" environment to ensure that error messages are in English. This DefaultLocale is defined in a way that if necessary (due to platform weirdness) it can be overridden at build time using LDFLAGS="-X "code.gitea.io/gitea/modules/git.DefaultLocale=C"" with C changed for the locale as necessary.
* Allow to add and remove all repositories to team.

When doing GET /api/v1/users/{user} as an unauthenticated user,
gitea throws a 500 because it's trying to dereference elements
from the context user. It wants to do this to see whether to
show the primary email and will do that if the logged in user
is admin or the user in question. However, if ctx.User is nil,
go gets really unhappy.
