* Changed IsAutomaticNameMode to GivenNameHasBeenChanged. Fixed errors in files according to golangci-lint rules
expand user, add claims to user
This commit expands the user table with additional fields that
can be retrieved from OIDC providers (and other places) and
uses this data in various tailscale response objects if it is
available.
This is the beginning of implementing
https://docs.google.com/document/d/1X85PMxIaVWDF6T_UPji3OeeUqVBcGj_uHRM5CI-AwlY/edit
trying to make OIDC more coherant and maintainable in addition
to giving the user a better experience and integration with a
provider.
remove usernames in magic dns, normalisation of emails
this commit removes the option to have usernames as part of MagicDNS
domains and headscale will now align with Tailscale, where there is a
root domain, and the machine name.
In addition, the various normalisation functions for dns names has been
made lighter not caring about username and special character that wont
occur.
Email are no longer normalised as part of the policy processing.
untagle oidc and regcache, use typed cache
This commits stops reusing the registration cache for oidc
purposes and switches the cache to be types and not use any
allowing the removal of a bunch of casting.
try to make reauth/register branches clearer in oidc
Currently there was a function that did a bunch of stuff,
finding the machine key, trying to find the node, reauthing
the node, returning some status, and it was called validate
which was very confusing.
This commit tries to split this into what to do if the node
exists, if it needs to register etc.

this commit denormalises the Tags related to a Pre auth key
back onto the preauthkey table and struct as a string list.
There was not really any real normalisation here as we just added
a bunch of duplicate tags with new IDs and preauthkeyIDs, lots of
GORM cermony but no actual advantage.
This work is the start to fixup tags which currently are not working
as they should.

* handle control protocol through websocket
The necessary behaviour is already in place,
but the wasm build only issued GETs, and the handler was not invoked.
* get DERP-over-websocket working for wasm clients
* Prepare for testing builtin websocket-over-DERP
Still needs some way to assert that clients are connected through websockets,
rather than the TCP hijacking version of DERP.
* integration tests: properly differentiate between DERP transports
* do not touch unrelated code
* linter fixes
* integration testing: unexport common implementation of derp server scenario
* fixup! integration testing: unexport common implementation of derp server scenario
* dockertestutil/logs: remove unhelpful comment
* update changelog

this commit changes and streamlines the dns_config into a new
key, dns. It removes a combination of outdates and incompatible
configuration options that made it easy to confuse what headscale
could and could not do, or what to expect from ones configuration.

* reformat code
This is mostly an automated change with `make lint`.
I had to manually please golangci-lint in routes_test because of a short
variable name.
* fix start -> strategy which was wrongly corrected by linter
* replace ephemeral deletion logic
this commit replaces the way we remove ephemeral nodes,
currently they are deleted in a loop and we look at last seen
time. This time is now only set when a node disconnects and
there was a bug (#2006) where nodes that had never disconnected
was deleted since they did not have a last seen.
The new logic will start an expiry timer when the node disconnects
and delete the node from the database when the timer is up.
If the node reconnects within the expiry, the timer is cancelled.
Fixes#2006

Added a new function `RegisterMethodToV1Enum()` to Node, converting the internal register method string to the corresponding V1 Enum value. Included corresponding unit test in `node_test.go` to ensure correct conversion for various register methods.
* correctly enable WAL log for sqlite
this commit makes headscale correctly enable write-ahead-log for
sqlite and adds an option to turn it on and off.
WAL is enabled by default and should make sqlite perform a lot better,
even further eliminating the need to use postgres.
It also adds a couple of other useful defaults.

This PR removes the complicated session management introduced in https://github.com/juanfont/headscale/pull/1791 which kept track of the sessions in a map, in addition to the channel already kept track of in the notifier.
Instead of trying to close the mapsession, it will now be replaced by the new one and closed after so all new updates goes to the right place.
The map session serve function is also split into a streaming and a non-streaming version for better readability.
RemoveNode in the notifier will not remove a node if the channel is not matching the one that has been passed (e.g. it has been replaced with a new one).
A new tuning parameter has been added to added to set timeout before the notifier gives up to send an update to a node.
Add a keep alive resetter so we wait with sending keep alives if a node has just received an update.
In addition it adds a bunch of env debug flags that can be set:
- `HEADSCALE_DEBUG_HIGH_CARDINALITY_METRICS`: make certain metrics include per node.id, not recommended to use in prod.
- `HEADSCALE_DEBUG_PROFILING_ENABLED`: activate tracing
- `HEADSCALE_DEBUG_PROFILING_PATH`: where to store traces
- `HEADSCALE_DEBUG_DUMP_CONFIG`: calls `spew.Dump` on the config object startup
- `HEADSCALE_DEBUG_DEADLOCK`: enable go-deadlock to dump goroutines if it looks like a deadlock has occured, enabled in integration tests.

This commit restructures the map session in to a struct
holding the state of what is needed during its lifetime.
For streaming sessions, the event loop is structured a
bit differently not hammering the clients with updates
but rather batching them over a short, configurable time
which should significantly improve cpu usage, and potentially
flakyness.
The use of Patch updates has been dialed back a little as
it does not look like its a 100% ready for prime time. Nodes
are now updated with full changes, except for a few things
like online status.

When Postgres is used as the backing database for headscale,
it does not set a limit on maximum open and idle connections
which leads to hundreds of open connections to the Postgres
server.
This commit introduces the configuration variables to set those
values and also sets default while opening a new postgres connection.
This commits removes the locks used to guard data integrity for the
database and replaces them with Transactions, turns out that SQL had
a way to deal with this all along.
This reduces the complexity we had with multiple locks that might stack
or recurse (database, nofitifer, mapper). All notifications and state
updates are now triggered _after_ a database change.
