@sashan and I were discussing the usefulness of the public facing api
for NEW_TOKEN support, and he has concerns over its usefulness and our
being stuck with it if we need to make changes later. Given that it is
a convience api for using multiple CTX-es to share a cache, its fine if
we remove it for now, as that seems like a less common use case.

closer reading of RFC 9000 indicates that a NEW_TOKEN token can be

so instead of creating a use once and discard pattern in the token api.
Let the tokens stick around until they are replaced with a new token
from the server. To do this, we need to ref count the tokens so that we
don't accidentally free them while a given client is waiting to send an
initial frame making use of them.

We have a chicken and egg problem.
Normally when we create a connection object in quic, we associate it
with a listener, and up the ref on the parent listener, which is fine.
However, now that we are pre-allocating user_ssl objects for incomming
connections we have a situation in which:
1) The pre-alocated connection object holds a ref on the listener
2) The application has no awareness of the quic connection object (and
so can't free it)
3) The freeing of the listener object never calls into the quic stack,
because its reference count may hold references from connections that
haven't been accepted yet
We could require that applications register a function for the
new_pending_conn callback, and track/free these pending connections, but
that seems like alot of extra unneeded work to place on the application
Instead:
a) add a quic_conn_st flag named accepted
b) When pre-allocating connections, clear the flag in (a) and _dont_
hold a reference to the parent listener
c) in SSL_accept_connection, set the accepted flag and reference the
listener
d) in ossl_quic_free drop the listener reference only if the accepted
flag is set
c) expressly free all user_ssl objects in ossl_quic_port_drop_incoming
