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>

closed #17378
Both errors from #17378 were caused by #15175.
Problem 1 (error with added file):
`ToUTF8WithFallbackReader` creates a `MultiReader` from a `byte[2048]` and the remaining reader. `CreateReaderAndGuessDelimiter` tries to read 10000 bytes from this reader but only gets 2048 because that's the first reader in the `MultiReader`. Then the `if size < 1e4` thinks the input is at EOF and just returns that.
Problem 2 (error with changed file):
The blob reader gets defer closed. That was fine because the old version reads the whole file into memory. Now with the streaming version the close needs to defer after the method.
* Prevent NPE on invalid diff
If ParseCompareInfo returns a nil compare info the defer function needs to ensure
that it does not attempt to close the HeadGitRepo.

This PR changes the compare page to make the "..." in the between branches a clickable
link. This changes the comparison type from "..." to "..". Similarly it makes the
initial compare icon clickable to switch the head and base branches.

* make sure headGitRepo is closed on err too
* refactor
* Fix git.Blob.DataAsync(): exec cancel since we already read all bytes (close pipe since we return a NopCloser)
Followup from #16562 prepare for #16567
* Rename ctx.Form() to ctx.FormString()
* Reimplement FormX func to need less code and cpu cycles
* Move code into own file
The CompareAndPullRequestPost handler for POST to /compare
incorrectly handles returning errors to the user. For a start
it does not set the necessary markers to switch SimpleMDE
but it also does not immediately return to the form.
This PR fixes this by setting the appropriate values, fixing
the templates and preventing the suggestion of a too long
title.
