Currently, the dpdk log is out to stdout/stderr and syslog.
We should support to output the log to another please, e.g. file or
glog.  

Why not use rte_openlog_stream() / rte_log_get_stream() ?

rte_openlog_stream seems it could set an external FILE* stream.
However, in the glog or C++ io stream, it's stream like std::cout.
I think it's hard to use a FILE* stream to unify them.

Also, FILE* is not a language-agnostic interface. Rust/D/etc consumers can't
use this API unless they obtain a FILE* from a compatible libc.
