Improve code comment review on mobile (#21461)
- Fix placement of avatar image, this was not placed in the
`comment-header-left` and add CSS to cover the limiting of width+height
of avatar for code-review comment on "Files changed" page. This fixes
the big noticeable avatar issue.
- Apply `margin-bottom` to the "next" button, so it's consistent with
the "previous" button.
- Make sure the "next"/"previous" start at `flex-start` on mobile and
not off-screen at `flex-end`. As well force them to have `flex: 1` so
they won't overflow on x-asis. This also requires the `width: 100%` for
the `.ui.buttons` div.
- Resolves #20074

Diff file tree tweaks (#21446)
- Left-align the diff stat line again like previously.
- Default the file tree to collapsed view, which means the tree will
rendered initially collapsed and it may "pop in" via JS if enabled. I
think this is more desirable than having the empty space for the tree
"pop out" like it currently does.
- Mute the icon, removing color unless hovered.
- Increase icon size and vertically center it.

Add filetree on left of diff view (#21012)
This PR adds a filetree to the left side of the files/diff view.

Initially the filetree will not be shown and may be shown via a new
"Show file tree" button.

Showing and hiding is using the same icon as github. Folders are
collapsible. On small devices (max-width 991 PX) the file tree will be
hidden.

Prevent invalid behavior for file reviewing when loading more files (#21230)
The problem was that many PR review components loaded by `Show more`
received the same ID as previous batches, which confuses browsers (when
clicked). All such occurrences should now be fixed.

Additionally improved the background of the `viewed` checkbox.

Lastly, the `go-licenses.json` was automatically updated.

Switch Unicode Escaping to a VSCode-like system (#19990)
This PR rewrites the invisible unicode detection algorithm to more
closely match that of the Monaco editor on the system. It provides a
technique for detecting ambiguous characters and relaxes the detection
of combining marks.

Control characters are in addition detected as invisible in this
implementation whereas they are not on monaco but this is related to
font issues.

Fix review excerpt (#18502)
Currently the "File Changed" tab of a PR is somehow broken. This is also true for the current release 1.16.0.

When you are on the "File Changed" tab, and want to look at code excerpt before or after the code changes, the layout breaks. You can test this on try.gitea.io here: https://try.gitea.io/testnotexisting/magic_enum/pulls/2/files

The problem occurs for the unified view and for the split view.

Kind of the same problem was there for commenting a line of code, this was fixed in #18321 and #18403.

For consistency, I changed the solution of #18321, I removed the ``colspan`` and instead added a ``<td>``. The goal was to have code similarly with the split view.

Also the separator line in the split view was in the wrong column, this was fixed too.* more consistent unified review comment

Multiple Escaping Improvements (#17551)
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>

Prevent NPE in CSV diff rendering when column removed (#17018)
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
