Partially fix#23050
After #22294 merged, it always has a warning log like `cannot get
context cache` when starting up. This should not affect any real life
but it's annoying. This PR will fix the problem. That means when
starting up, getting the system settings will not try from the cache but
will read from the database directly.

This PR refactors and improves the password hashing code within gitea
and makes it possible for server administrators to set the password
hashing parameters
In addition it takes the opportunity to adjust the settings for `pbkdf2`
in order to make the hashing a little stronger.
The majority of this work was inspired by PR #14751 and I would like to
thank @boppy for their work on this.
Thanks to @gusted for the suggestion to adjust the `pbkdf2` hashing
parameters.

Allow back-dating user creation via the `adminCreateUser` API operation.
`CreateUserOption` now has an optional field `created_at`, which can
contain a datetime-formatted string. If this field is present, the
user's `created_unix` database field will be updated to its value.
This is important for Blender's migration of users from Phabricator to
Gitea. There are many users, and the creation timestamp of their account
can give us some indication as to how long someone's been part of the
community.
The back-dating is done in a separate query that just updates the user's
`created_unix` field. This was the easiest and cleanest way I could
find, as in the initial `INSERT` query the field always is set to "now".
To avoid duplicated load of the same data in an HTTP request, we can set
a context cache to do that. i.e. Some pages may load a user from a
database with the same id in different areas on the same page. But the
code is hidden in two different deep logic. How should we share the
user? As a result of this PR, now if both entry functions accept
`context.Context` as the first parameter and we just need to refactor
`GetUserByID` to reuse the user from the context cache. Then it will not
be loaded twice on an HTTP request.
But of course, sometimes we would like to reload an object from the
database, that's why `RemoveContextData` is also exposed.
The core context cache is here. It defines a new context
```go
type cacheContext struct {
ctx context.Context
data map[any]map[any]any
lock sync.RWMutex
}
var cacheContextKey = struct{}{}
func WithCacheContext(ctx context.Context) context.Context {
return context.WithValue(ctx, cacheContextKey, &cacheContext{
ctx: ctx,
data: make(map[any]map[any]any),
})
}
```
Then you can use the below 4 methods to read/write/del the data within
the same context.
```go
func GetContextData(ctx context.Context, tp, key any) any
func SetContextData(ctx context.Context, tp, key, value any)
func RemoveContextData(ctx context.Context, tp, key any)
func GetWithContextCache[T any](ctx context.Context, cacheGroupKey string, cacheTargetID any, f func() (T, error)) (T, error)
```
Then let's take a look at how `system.GetString` implement it.
```go
func GetSetting(ctx context.Context, key string) (string, error) {
return cache.GetWithContextCache(ctx, contextCacheKey, key, func() (string, error) {
return cache.GetString(genSettingCacheKey(key), func() (string, error) {
res, err := GetSettingNoCache(ctx, key)
if err != nil {
return "", err
}
return res.SettingValue, nil
})
})
}
```
First, it will check if context data include the setting object with the
key. If not, it will query from the global cache which may be memory or
a Redis cache. If not, it will get the object from the database. In the
end, if the object gets from the global cache or database, it will be
set into the context cache.
An object stored in the context cache will only be destroyed after the
context disappeared.
As part of administration sometimes it is appropriate to forcibly tell
users to update their passwords.
This PR creates a new command `gitea admin user must-change-password`
which will set the `MustChangePassword` flag on the provided users.

When importing a repository via `gitea restore-repo`, external users
will get remapped to an admin user. This admin user is obtained via
`users.GetAdminUser()`, which unfortunately picks a more-or-less random
admin to return.
This makes it hard to predict which admin user will get assigned. This
patch orders the admin by ascending ID before choosing the first one,
i.e. it picks the admin with the lowest ID.
Even though it would be nicer to have full control over which user is
chosen, this at least gives us a predictable result.
Fix#22281
In #21621 , `Get[V]` and `Set[V]` has been introduced, so that cache
value will be `*Setting`. For memory cache it's OK. But for redis cache,
it can only store `string` for the current implementation. This PR
revert some of changes of that and just store or return a `string` for
system setting.
If user has reached the maximum limit of repositories:
- Before
- disallow create
- allow fork without limit
- This patch:
- disallow create
- disallow fork
- Add option `ALLOW_FORK_WITHOUT_MAXIMUM_LIMIT` (Default **true**) :
enable this allow user fork repositories without maximum number limit

`hex.EncodeToString` has better performance than `fmt.Sprintf("%x",
[]byte)`, we should use it as much as possible.
I'm not an extreme fan of performance, so I think there are some
exceptions:
- `fmt.Sprintf("%x", func(...)[N]byte())`
- We can't slice the function return value directly, and it's not worth
adding lines.
```diff
func A()[20]byte { ... }
- a := fmt.Sprintf("%x", A())
- a := hex.EncodeToString(A()[:]) // invalid
+ tmp := A()
+ a := hex.EncodeToString(tmp[:])
```
- `fmt.Sprintf("%X", []byte)`
- `strings.ToUpper(hex.EncodeToString(bytes))` has even worse
performance.

and also builtin check on `db.TxContext` and `db.WithTx`.
There is also a new method `db.AutoTx` has been introduced but could be used by other PRs.
`WithTx` will always open a new transaction, if a transaction exist in context, return an error.
`AutoTx` will try to open a new transaction if no transaction exist in context.
That means it will always enter a transaction if there is no error.

A lot of our code is repeatedly testing if individual errors are
specific types of Not Exist errors. This is repetitative and unnecesary.
`Unwrap() error` provides a common way of labelling an error as a
NotExist error and we can/should use this.
This PR has chosen to use the common `io/fs` errors e.g.
`fs.ErrNotExist` for our errors. This is in some ways not completely
correct as these are not filesystem errors but it seems like a
reasonable thing to do and would allow us to simplify a lot of our code
to `errors.Is(err, fs.ErrNotExist)` instead of
`package.IsErr...NotExist(err)`
I am open to suggestions to use a different base error - perhaps
`models/db.ErrNotExist` if that would be felt to be better.

The rule is just: user/org is visible if

- The doer is not restricted and the user/org is public or limited
Users who are following or being followed by a user should only be

The setting `DEFAULT_SHOW_FULL_NAME` promises to use the user's full name everywhere it can be used.
Unfortunately the function `*user_model.User.ShortName()` currently uses the `.Name` instead - but this should also use the `.FullName()`.
Therefore we should make `*user_model.User.ShortName()` base its pre-shortened name on the `.FullName()` function.

Copied from what I wrote on #19133 discussion: Handling username case is a very tricky issue and I've already encountered a Mastodon <-> Gitea federation bug due to Gitea considering Ta180m and ta180m to be the same user while Mastodon thinks they are two different users. I think the best way forward is for Gitea to only use the original case version of the username for federation so other AP software don't get confused.

* If httpsig verification fails, fix Host header and try again
This fixes a very rare bug when Gitea and another AP server (confirmed to happen with Mastodon) are running on the same machine, Gitea fails to verify incoming HTTP signatures. This is because the other AP server creates the sig with the public Gitea domain as the Host. However, when Gitea receives the request, the Host header is instead localhost, so the signature verification fails. Manually changing the host header to the correct value and trying the veification again fixes the bug.
* Revert "If httpsig verification fails, fix Host header and try again"
This reverts commit f53e46c721a037c55facb9200106a6b491bf834c.
The bug was actually caused by nginx messing up the Host header when reverse-proxying since I didn't have the line `proxy_set_header Host $host;` in my nginx config for Gitea.

When calling DumpRepository and RestoreRepository on the same Gitea
instance, the users are preserved: all labels, issues etc. belong to
the external user who is, in this particular case, the local user.
Dead code verifying g.gitServiceType.Name() == "" (i.e. plain git) is
removed. The function is never called because the plain git downloader
does not migrate anything that is associated to a user, by definition.
Errors returned by GetUserIDByExternalUserID are no longer ignored.
The userMap is used when the external user is not kown, which is the
most common case. It was only used when the external user exists
which happens less often and, as a result, every occurence of an
unknown external user required a SQL query.

- The current implementation of `RandomString` doesn't give you a most-possible unique randomness. It gives you 6*`length` instead of the possible 8*`length` bits(or as `length`x bytes) randomness. This is because `RandomString` is being limited to a max value of 63, this in order to represent the random byte as a letter/digit.
- The recommendation of pbkdf2 is to use 64+ bit salt, which the `RandomString` doesn't give with a length of 10, instead of increasing 10 to a higher number, this patch adds a new function called `RandomBytes` which does give you the guarentee of 8*`length` randomness and thus corresponding of `length`x bytes randomness.
- Use hexadecimal to store the bytes value in the database, as mentioned, it doesn't play nice in order to convert it to a string. This will always be a length of 32(with `length` being 16).
- When we detect on `Authenticate`(source: db) that a user has the old format of salt, re-hash the password such that the user will have it's password hashed with increased salt.
