`ALTER TABLE DROP ... IF EXISTS ...` is only supported in SQL Server >16.
The `IF EXISTS` here is a belt-and-braces and does not need to be present. Therefore
can be dropped.
We need to figure out some way of restricting our SQL syntax against the minimum
version of SQL Server we will support.
My suspicion is that `ALTER DATABASE database_name SET COMPATIBILITY_LEVEL = 100` may
do that but there may be other side-effects so I am not whether to do that.

* Fix add authentication page
There is a regression in #16199 whereby the add authentication page
fails to react to the change in selected type.
This is due to the String() method on the LoginSourceType which is ameliorated
with an Int() function being added.
Following on from this there are a few other related bugs.
Fix#16541

`models` does far too much. In particular it handles all `UserSignin`.
It shouldn't be responsible for calling LDAP, SMTP or PAM for signing in.
Therefore we should move this code out of `models`.
This code has to depend on `models` - therefore it belongs in `services`.
There is a package in `services` called `auth` and clearly this functionality belongs in there.
Plan:
- [x] Change `auth.Auth` to `auth.Method` - as they represent methods of authentication.
- [x] Move `models.UserSignIn` into `auth`
- [x] Move `models.ExternalUserLogin`
- [x] Move most of the `LoginVia*` methods to `auth` or subpackages
- [x] Move Resynchronize functionality to `auth`
- Involved some restructuring of `models/ssh_key.go` to reduce the size of this massive file and simplify its files.
- [x] Move the rest of the LDAP functionality in to the ldap subpackage
- [x] Re-factor the login sources to express an interfaces `auth.Source`?
- I've done this through some smaller interfaces Authenticator and Synchronizable - which would allow us to extend things in future
- [x] Now LDAP is out of models - need to think about modules/auth/ldap and I think all of that functionality might just be moveable
- [x] Similarly a lot Oauth2 functionality need not be in models too and should be moved to services/auth/source/oauth2
- [x] modules/auth/oauth2/oauth2.go uses xorm... This is naughty - probably need to move this into models.
- [x] models/oauth2.go - mostly should be in modules/auth/oauth2 or services/auth/source/oauth2
- [x] More simplifications of login_source.go may need to be done
- Allow wiring in of notify registration - *this can now easily be done - but I think we should do it in another PR* - see #16178
- More refactors...?
- OpenID should probably become an auth Method but I think that can be left for another PR
- Methods should also probably be cleaned up - again another PR I think.
- SSPI still needs more refactors.* Rename auth.Auth auth.Method
* Restructure ssh_key.go
- move functions from models/user.go that relate to ssh_key to ssh_key
- split ssh_key.go to try create clearer function domains for allow for
future refactors here.

* Add LRU mem cache implementation (#16226)
The current default memory cache implementation is unbounded in size and number of
objects cached. This is hardly ideal.
This PR proposes creating a TwoQueue LRU cache as the underlying cache for Gitea.
The cache is limited by the number of objects stored in the cache (rather than size)
for simplicity. The default number of objects is 50000 - which is perhaps too small
as most of our objects cached are going to be much less than 1kB.
It may be worth considering using a different LRU implementation that actively limits
sizes or avoids GC - however, this is just a beginning implementation.

Fix#15521
Signed-off-by: Andrew Thornton <art27@cantab.net>
One of the reasons why #16447 was needed and why #16268 was needed in
the first place was because it appears that editing ldap configuration
doesn't get tested.
This PR therefore adds a basic test that will run the edit pipeline.
In doing so it's now clear that #16447 and #16268 aren't actually
solving #16252. It turns out that what actually happens is that is that
the bytes are actually double encoded.
This PR now changes the json unmarshal wrapper to handle this double
encode.

Unfortunately some old repositories can have tags with empty Tagger, Commit
or Author. Go-Git variants will always have empty values for these whereas
the native git variant leaves them at nil. The simplest solution is just to
always have these set to empty Signatures.

Therefore add some handling to this and add logging and adjust broken
logging elsewhere in this migration.
