For test images manually generated to contain only up prediction,
timing results:
8380x3032 255x185
before: 138635 1992
after: 139232 1996
Actually jumping to the proper version depending on the alignment:
8380x3032: 138767
A 0.5% speed improvement for gigantic images is not worth the code
duplication.
Fixes ticket #4148

This is needed to avoid banding artifacts when gammaing the picture.
Currently, if done with a video filter, the process is done on uints
instead of full float.

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.

Try to detect "$cc -static" without "pkg-config --static".
Also, when a library detection using pkg-config fails,
make it explicit this was pkg-config.
The require variant dies if the package is not present.
The check variant does not import the flags to the used list.
The new variant imports the flags if the package is present
but does not die if it is not.
The new call graph is: require -> use -> check.
Use use_pkg_config for libx264 and libsmbclient: more readable
and three external call less per library.

This allows to load metadata entries longer than 1024 bytes.
Displaying them is still limited to 1024 characters, but applications
can load them fully now.
