In the case of misuse or misunderstanding from a developer whereby,
if `sel` can receive user-controlled data, jQuery `$(sel)` can lead to the
creation of a new element. Current usage is using hard-coded selectors
in the templates, but nobody prevents that from expanding to
user-controlled somehow.
This contains some additional fixes and small nits related to #17957

* Fix CSS specificity issue with easymde's css
PR #18069 introduced a regression in certain overwritten editor styles
because the dynamic loading of easymde.min.css causes its's style to
apply after our supposed override styles.
Solve this by bundling the styles into index.css. We should later aim to
completely replace easymde.min.css completely with our own styles so there
are no more conflicts.

Since we are using EasyMDE now, we do not need to keep the SimpleMDE code anymore.
This PR removes all legacy SimpleMDE code, and makes some related changes:
* `createCommentEasyMDE` can accept native DOM element, and it doesn't need `jQuery.data` to store EasyMDE editor object (as discussed about the frontend guideline).
* introduce `getAttachedEasyMDE` to get the attached EasyMDE editor object, it's easier to find all the usage of EasyMDE.
* rename variable names from `$simplemde` to `easyMDE`, the `$` was incorrect because it is a EasyMDE editor, not a jQuery object.
With this PR, it will be easier to do more refactoring or replacing EasyMDE with other editors.
* Refactor install page (db type)
* set correct default DB HOST for different DB TYPE
* remove legacy TiDB from documents

There are multiple places where Gitea does not properly escape URLs that it is building and there are multiple places where it builds urls when there is already a simpler function available to use this.
This is an extensive PR attempting to fix these issues.
1. The first commit in this PR looks through all href, src and links in the Gitea codebase and has attempted to catch all the places where there is potentially incomplete escaping.
2. Whilst doing this we will prefer to use functions that create URLs over recreating them by hand.
3. All uses of strings should be directly escaped - even if they are not currently expected to contain escaping characters. The main benefit to doing this will be that we can consider relaxing the constraints on user names and reponames in future.
4. The next commit looks at escaping in the wiki and re-considers the urls that are used there. Using the improved escaping here wiki files containing '/'. (This implementation will currently still place all of the wiki files the root directory of the repo but this would not be difficult to change.)
5. The title generation in feeds is now properly escaped.
6. EscapePound is no longer needed - urls should be PathEscaped / QueryEscaped as necessary but then re-escaped with Escape when creating html with locales Signed-off-by: Andrew Thornton <art27@cantab.net>

Fixes#16837 if a column is deleted.
We were clobbering the columns that were added by looping through the aline (base) and then when bline (head) was looped through, it clobbered what was in the "cells" array that is show in the diff, and then left a nil cell because nothing was shifted.
This fix properly shifts the cells, and properly puts the b cell either at its location or after, according to what the aline placed in the cells.
This includes test, adding a new test function since adding/removing cells works best with three columns, not two, which results in 4 columns of the resulting cells because it has a deleted column and an added column. If you try this locally, you can try those cases and others, such as adding a column.
There was no need to do anything special for the rows when `aline == 0 || bline == 0` so that was removed. This allows the same code to be used for removed or added lines, with the bcell text always being the RightCell, acell text being the LeftCell.
I still added the patch zeripath gave at https://github.com/go-gitea/gitea/issues/16837#issuecomment-913007382 so that just in case for some reason a cell is nil (which shouldn't happen now) it doesn't throw a 500 error, so the user can at least view the raw diff.
Also fixes in the [view.go](https://github.com/go-gitea/gitea/pull/17018/files#diff-43a7f4747c7ba8bff888c9be11affaafd595fd55d27f3333840eb19df9fad393L521) file how if a CSV file is empty (either created empty or if you edit it and remove all contents) it throws a huge 500 error when you then save it (when you view the file). Since we allow creating, saving and pushing empty files, we shouldn't throw an error on an empty CSV file, but just show its empty contents. This doesn't happen if it is a Markdown file or other type of file that is empty.
EDIT: Now handled in the markup/csv renderer code

Unfortunately #17301 broke the restriction of the dashboard repolist to

There is also a weird alignment problem - not caused by that PR - where

simply reduces the padding on these items and switches the justification

Of note, the behaviour of the template selector dropdown on the repo
