Make the output valid INI serialization.

Do not use decimals if not needed.

This is easier to parse with automated tools.

Fixes "memleak" on closing avprobe to make valgrind happy.

This is useful for writing unit tests.

Calling the init function will become mandatory at some later
point. By calling it, more heavy network init (such as SSL/TLS
library init) can be done once at startup, instead of implicitly
when used (which could lead to it being done a number of times).

This way it can be applied to cmdutils too -- e.g. showing the banner
and printing startup messages.

This is the first step to removing the globals plague from avtools.

Allows cmdutils to call each tool's own cleanup function.

Replace it with newly introduced libavutil API.

Adds support for decoder-private options and makes setting other options
simpler.

Make ff* tools only accept opt_* functions taking two arguments.

The distinction between functions with one and two arguments is quite
pointless. Simplify parse_options() code.

Replace "codec (id=%d)" with "codec with id %d", slightly more
readable.

sample_aspect_ratio is known.

Avoid to show bogus values, which may confuse both the human and the
machine reader.
