[syslog-ng] Host/port from environment variables

[Scheidler, Balázs]

Hi,

you can use backticks to refer to environment variables. I think these were
introduced in 3.4.

tcp(port(`MY_PORT`))


It can also use values defined within the configuration files using the
@define pragma:

@define MY_PORT 12345

Or something like that.
