Merge libavcore into libavutil

It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody...

cmdutils: fix codec-specific options from preset

in opt_names/values. This change causes the strings to be dup'd then
freed in uninit_opts.
