Amaury Denoyelle 8de0807b74 MEDIUM: conn/muxes/ssl: reinsert BE priv conn into sess on IO completion ...

When dealing with input/output on a connection related handler, special
care must be taken prior to access the connection if it is considered as
idle, as it could be manipulated by another thread. Thus, connection is
first removed from its idle tree before processing. The connection is
reinserted on processing completion unless it has been freed during it.

Idle private connections are not concerned by this, because takeover is
not applied on them. However, a future patch will implement purging of
these connections along with regular idle ones. As such, it is necessary
to also protect private connections usage now. This is the subject of
this patch and the next one.

With this patch, input/output handlers epilogue of
muxes/SSL/conn_notify_mux() are adjusted. A new code path is able to
deal with a connection attached to a session instead of a server. In
this case, session_reinsert_idle_conn() is used. Contrary to
session_add_conn(), this new function is reserved for idle connections
usage after a temporary removal.

Contrary to _srv_add_idle() used by regular idle connections,
session_reinsert_idle_conn() may fail as an allocation can be required.
If this happens, the connection is immediately destroyed.

This patch has no effect for now. It must be coupled with the next one
which will temporarily remove private idle connections on input/output
handler prologue.
