- update to 2.1.4
    - enabling mixed linking to compile only non-system libs statically
    - lots of packaging updates to be able to build on RHEL4,5, Fedora9+ and be
        parallel-installable with rsyslog and/or sysklogd on those platforms
    - removing BR for flex & byacc to try to prevent files from being
        regenerated
    - fixing build error with cfg-lex.l and flex 2.5.4
    - Fixed a possible DoS condition triggered by a destination port
        unreachable ICMP packet received from a UDP destination. syslog-ng
        started eating all available memory and CPU until it crashed if this
        happened.
    - Fixed the rate at which files regular were read using the file() source.
    - Report connection breaks as a write error instead of reporting POLLERR as
        the write error path reports more sensible information in the logs.
