Also change comparing stream size from (<=0 && < 16384) to (<=0 && >16384)

This and earlier change to add access to prefix should fix usage of eg
http://media.meteo.it/vsat.asx playlist-file.

(cherry picked from commit b3d9ea87aa40d43f081b8fcecd7d0126e6865196)

LibVLC is not calling gpg_error functions anywhere. Linking gpg-error
causes problems with *correctly* built libgcrypt (e.g. incorrect
package dependencies).

This reverts commit f865a816.

They are used nowhere in the code, and just clutter the build system

This allow to have channelnames on saved xspf-playlist from dvb-scanning.

It is not described in the msdn documentation, but planar 420
seems to be supported by a lot of video cards.
