close#33086
* Add a special value for "SSH_USER" setting: `(DOER_USERNAME)`
* Improve parseRepositoryURL and add tests (now it doesn't have hard
dependency on some setting values)
Many changes are just adding "ctx" and "doer" argument to functions.
By the way, improve app.example.ini, remove all `%(key)s` syntax, it
only makes messy and no user really cares about it.

X-Forwarded-Host has many problems: non-standard, not well-defined
(X-Forwarded-Port or not), conflicts with Host header, it already caused
problems like #31907. So do not use X-Forwarded-Host, just use Host
header directly.
Official document also only uses `Host` header and never mentioned
others.
Fix#31361, and add tests
And this PR introduces an undocumented & debug-purpose-only config
option: `USE_SUB_URL_PATH`. It does nothing for end users, it only helps
the development of sub-path related problems.
And also fix#31366

Fix#31002
1. Mention Make sure `Host` and `X-Fowarded-Proto` headers are correctly passed to Gitea
2. Clarify the basic requirements and move the "general configuration" to the top
3. Add a comment for the "container registry"
4. Use 1.21 behavior if the reverse proxy is not correctly configured
