psy-rd should be default on when subme >= 6 (x264 library mentions
this), and I'm not sure how much this options is used in 'normal use'

default qp=-1, so it can be detected even if theres bitrate

change default crf=23 as x264 has

if user defines qcomp<=0.1 then define ABR-mode, otherwise CRF-mode.
And override it to QP-mode if user has defined qp-value.

I thought of using a completely separate setting. But that would break
backward compatibility. I think it is best to let --file-caching
increase caching for all files. I guess that is how TheDJ intended it.

getaddrinfo() may list IPv4 before IPv6 depending on system
configuration.

 It will allows to control the moment at which the meta are updated
to fix the delay introduced by timeshift and buffering.
 It will also simplify the way meta data are read by demuxers.

No functionnal changes.
