This commit fixes the constraint syntax so it is both valid for
sqlite and postgres.
To validate this, I've added a new postgres testing library and a
helper that will spin up local postgres, setup a db and use it in
the constraints tests. This should also help testing db stuff in
the future.
postgres has been added to the nix dev shell and is now required
for running the unit tests.

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.

* 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
* 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.

most of the time we dont even check this error and checking
the string for particular errors is very flake as different
databases (sqlite and psql) use different error messages, and
some users might have it in other languages.

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.

* make Node object use actualy tailscale key types
This commit changes the Node struct to have both a field for strings
to store the keys in the database and a dedicated Key for each type
of key.
The keys are populated and stored with Gorm hooks to ensure the data
is stored in the db.

This commit changes the internals of the mapper to
track all the changes to peers over its lifetime.
This means that it no longer depends on the database
and this should hopefully help with locks and timing issues.
When the mapper is created, it needs the current list of peers,
the world view, when the polling session was started. Then as
update changes are called, it tracks the changes and generates
responses based on its internal list.
As a side, the types.Machines and types.MachinesP, as well as
types.Machine being passed as a full struct and pointer has been
changed to always be pointers, everywhere.

This commit replaces the timestamp based state system with a new
one that has update channels directly to the connected nodes. It
will send an update to all listening clients via the polling
mechanism.
It introduces a new package notifier, which has a concurrency safe
manager for all our channels to the connected nodes.

Prior to the code reorg, we would generate rules from the Policy and
store it on the global object. Now we generate it on the fly for each node
and this commit cleans up the old variables to make sure we have no
unexpected side effects.
