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>

* Correctly handle failed migrations
There is a bug in handling failed migrations whereby the migration task gets decoupled
from the migration repository. This leads to a failure of the task to get deleted with
the repository and also leads to the migration failed page resulting in a ISE.
This PR removes the zeroing out of the task id from the migration but also makes
the migration handler tolerate missing tasks much nicer.

There is a small bug in the way that repo access is checked in
repoAssignment: Accessibility is checked by checking if the user has a
marked access to the repository instead of checking if the user has any
team granted access.
This PR changes this permissions check to use HasAccess() which does the

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.
The API convert.toUser function makes the incorrect assumption that full names could
be rendered as is without being escaped. It therefore runs the names through
markup.Sanitize which leads to a double escape of user full names. This
pr stops this.

We have the `AppState` module now, it can store app related data easily. We do not need to create separate tables for each feature.
So the update checker can use `AppState` instead of a one-row dedicate table.
And the code of update checker is moved from `models` to `modules`.
Gitea writes its own AppPath into git hook scripts. If Gitea's AppPath changes, then the git push will fail.
This PR:
* Introduce an AppState module, it can persist app states into database
* During GlobalInit, Gitea will check if the current AppPath is the same as last one. If they don't match, Gitea will sync git hooks.
* Refactor some code to make them more clear.
* Also, "Detect if gitea binary's name changed" #11341 is related, we call models.RewriteAllPublicKeys to update ssh authorized_keys file
* Offer rsa-sha2-512 and rsa-sha2-256 algorithms in internal SSH
There is a subtle bug in the SSH library x/crypto/ssh which makes the incorrect
assumption that the public key type is the same as the signature algorithm type.
This means that only ssh-rsa signatures are offered by default.
This PR adds a workaround around this problem.

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
Convert the old mirror syncing queue to the more modern queue format.

core.protectNTFS protects NTFS from files which may be difficult to remove or interact
with using the win32 api, however, it also appears to prevent such files from
being entered into the git indexes - fundamentally causing breakages with PRs that
affect these files. However, deliberately setting this to false may cause security
issues due to the remain sparse checkout of files in the merge pipeline.

Why this refactor
The goal is to move most files from `models` package to `models.xxx` package. Many models depend on avatar model, so just move this first.
And the existing logic is not clear, there are too many function like `AvatarLink`, `RelAvatarLink`, `SizedRelAvatarLink`, `SizedAvatarLink`, `MakeFinalAvatarURL`, `HashedAvatarLink`, etc. This refactor make everything clear:
* user.AvatarLink()
* user.AvatarLinkWithSize(size)
* avatars.GenerateEmailAvatarFastLink(email, size)
* avatars.GenerateEmailAvatarFinalLink(email, size)
And many duplicated code are deleted in route handler, the handler and the model share the same avatar logic now.
Nodeinfo is a way to expose certain metadata about a server for use of discovery regarding functionality of its federation capabilities.
Two endpoints are required:
1. `/.well-known/nodeinfo` which informs client where it can find the location of the location of its metadata (including which version of the schema is used)
2. the endpoint which exposes the metadata in json format according to schema.
Notes:
* `openRegistrations` is a required field, but I propose to set to false as default in case someone writes a crawler to discover "open" gitea instances
* to limit data leakage I also propose to not include the `usage` field (note it is required so it should be included, but left as empty).

One of the issues holding back performance of the API is the problem of hashing.
Whilst banning BASIC authentication with passwords will help, the API Token scheme
still requires a PBKDF2 hash - which means that heavy API use (using Tokens) can
still cause enormous numbers of hash computations.
A slight solution to this whilst we consider moving to using JWT based tokens and/or
a session orientated solution is to simply cache the successful tokens. This has some
security issues but this should be balanced by the security issues of load from
hashing.
