Handle /derp/latency-check (#2227)
According to 15fc6cd966
the routes `/derp/probe` and `/derp/latency-check` are the same and
different versions of the tailscale client use one or the other
endpoint.

Also handle /derp/latency-check

Redo OIDC configuration (#2020)
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.

Add compatibility with only websocket-capable clients (#2132)
* 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

Simplify windows setup instructions (#2114)
* Simplify /windows to the bare minimum. Also remove the
  /windows/tailscale.reg endpoint as its generated file is no longer
  valid for current Tailscale versions.
* Update and simplify the windows documentation accordingly.
* Add a "Unattended mode" section to the troubleshooting section
  explaining how to enable "Unattended mode" in the via the Tailscale
  tray icon.
* Add infobox about /windows to the docs

validate policy against nodes, error if not valid (#2089)
* validate policy against nodes, error if not valid

this commit aims to improve the feedback of "runtime" policy
errors which would only manifest when the rules are compiled to
filter rules with nodes.

this change will in;

file-based mode load the nodes from the db and try to compile the rules on
start up and return an error if they would not work as intended.

database-based mode prevent a new ACL being written to the database if
it does not compile with the current set of node.

Fixes #2073

replace ephemeral deletion logic (#2008)
* 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

Simplify map session management (#1931)
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.

58c94d2bd3 Rework map session
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.

Replace database locks with transactions (#1701)
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.
