char * can alias anything, and Winsock relies on that. Unfortunately,
the compiler still issues warnings. This works around that.

Fix support for 32-bits platforms.
Regression from 46ea30cd.

This is not guaranteed.

Originally, POSIX made it unsigned. This was relaxed in newer releases,
but unsigned makes more sense anyway since it expressses a size.

This also improves error reporting to the OS for actions that can fail.

This reimplements navigation with chapters and sets the player button state correctly in detached vout windows

Fixes #8912.

This retains the existing meanings of 0 and 1 for backward
compatibility with existing vlcrc files. 2 is added for fullscreen-only
inhibit (refs #8912).
