ffmpeg and ffplay use the loglevel as well as libpostproc, libswscale

show_foo() functions are declared as void show_foo(void), but called as
int show_foo(const char*, const char*).

Make it print a list of AVCodecDescriptors.

Add new -decoders and -encoders options that print lists of decoders and
encoders respectively.

Also document it and replace undocumented and inconsistent
