FFABS(INT_MIN) is not safe. Alternative of using FFNABS is not as
readable.

Some of the defaults may be harmful (like buffer size).
It is good user is aware of that.

This prevents the situation when user set option to 0 and ffserver
threats it as not set value, so applies the default.

Options are already set to its defaults by AVOption API.
The only difference is for qmin, new default is 2, ffserver set to 3.
It is dead code because if condition is not meet unless user set option to 0.
Meeting condition would mean that ffserver overwrites explicity set option.

Moving line_num into FFServerConfig as parser state,
saves many passes of it aside of FFServerConfig pointer.

ffserver_save_avoption() and ffserver_opt_preset() have
redundant arguments. They can be obtained basing on media type.
This simplifies uses and reduce chance for a mistake.

So far AVCodecContext was created without codec specified.
This causes internal data to not be initialized to defaults.

This commit postpone context creation until all information is gathered.
