[syslog-ng] [PATCH] basicfuncs: Implement a $(now) template function.

[Gergely Nagy]

This implements a new basic template function: $(now), which will
return the current time (seconds since the epoch) as of calling the
template function.

For the rare case that the time of template expansion is needed, or
cached_gmtime() granularity is not enough.
