d899fe5936 Use real setters for the eventlog config. 
This makes it possible to have a base config that the callers can
modify instead of replacing the config wholesale.

e92d10011e Rename sa_len -> sa_size to avoid a conflict on UnixWare and others. 
On some systems, sa_len is a #define for 4.4BSD compatibility.

cbad17a994 Move inclusion of compat headers up with the system headers. 
Now that sudo_dso_public is defined in config.h we don't need sudo_compat.h
before including the compat headers.

83d1bee918 Rename sudo_parse_host_port -> iolog_parse_host_port and mv to lib/iolog 
It is not used outside of the I/O log client and server and the
host:port syntax may change in the future.

fc79cbc317 Only enable TLS listener by default if we have a cert for it. 
We want the log server to work with the default configuration.  If
the default certificate path exists, it will be used with the default
listener.  If the user explicitly enabled a TLS listener we always
attempt to use it.  If TLS was specified but no cert file was set,
the default location will be used (and an error will occur if the
cert cannot be loaded).

1659d96c55 Use port 30343 for plaintext and port 30344 for TLS. 
For TLS connections we now do the TLS handshake immediately before
the ServerHello message.  This lets the client recieve an alert
from the server is there is a handshake error after the TLS connect
has succeeded.  It also means that the contents of the ServerHello
are protected from a man-in-the-middle attack.

b5a317aeb9 Add support for a tls flag in sudo_parse_host_port(). 
If the string "(tls)" appears at the end, the tls flag is set to true
and the default tls port is used if necessary.

f40b4c2887 Open event log at config time instead of open/close for each entry. 
If logging via syslog, do the openlog() at config time instead.
We still lock the log file prior to writing to it but unlock
immediately after.

25542216fe Fix support for reloading the config in sudo_logsrvd. 
We need to re-initialize the TLS server context.
Also fix a memory leak of the TLS parameters on reload.

aaf5d0dc6e Read logsrvd.conf in two steps: first read, then apply if OK. 
This fixes a problem where when logsrvd.conf was reloaded while
running (due to SIGHUP) and there was an error we could end up with
a partial config.
