Introduce a protobuf-generated ReloadableConfig (cfg.proto) to hold all
fields that reload on SIGHUP, and separate them from static_cfg_st, which
holds fields that require a server restart. Named vhosts inherit from the
default vhost via a pack/unpack round-trip. Adding a new config field
only requires editing cfg.proto. Struct and accessor names (ReloadableConfig,
static_cfg_st, GETRCONFIG, GETSCONFIG) now reflect each field's lifetime.
A new unit test covers the full inheritance path.

Add 'terminate user', 'terminate id' and 'terminate session' commands
to occtl that disconnect users and invalidate their session cookies,
preventing reconnection with cached credentials.
Short session IDs are resolved to full safe_id by fetching the cookie
list from sec-mod via CTL_CMD_LIST_COOKIES with prefix matching and
ambiguity detection. Active sessions trigger a warning before
invalidation.
Add integration tests for all three terminate commands.

- Fixes an issue #599 where the session timeout could be bypassed
by reconnecting, such as through a laptop lid close/open cycle.
- Adds 'Session started at:' field to 'occtl show user' output.

Added current timestamp comparison to ensure only active bans
are shown by 'occtl show ip bans'.
Closes: #675.

Silence misleading debug message on server startup since absence
of the socket file is normal and expected.

Separated the logging logically from any remaining debugging
features. Introduced command line option for logging to stderr
only (for systemd and containers). The default log level is set
to (2) info.

This avoids warnings and static analyzers complains about
libev functions hiding the global 'loop' variable.

Previously when we were disconnecting a user there were few seconds
after which the cookie was still valid, so a reconnect would succeed
by the same user. This change ensures that a disconnected (via occtl)
user cannot re-use the same cookie to connect. That enables a safe
user removal from the authentication database, and from run-time.

This provides virtualized server configurations which take
effect after client connection when client hello is received.

Also added different values to keep authentication failures
and closed sessions, in total and per accounting period.

That is, store:
* number of timed out sessions
* number of timed out due being idle sessions
* number of errored sessions
* total number of session handled (closed)
* total number of kbytes sent
* total number of kbytes received
* minimum MTU seen
* maximum MTU seen
* total authentication failures
* average/max authentication time (in secs)
* average/max session time (in minutes)

Use instead a value derived from it, to avoid access to the debugging
log files, or radius result to access to the server.

That is, to allow referencing to these values from proc_st
without fearing of them being invalidated on a config reload. We
perform a cleanup of these values on the server periodic check.
We now use a common structure in SESSION_REPLY and AUTH_REP
messages. That structure is generated by sec-mod and forwarded
by main to worker, thus eliminating the need to create passing
code for each new user-config variable being added.
