    Validate the protocol xml during scanning · f66e2d53

    Embed the wayland.dtd protocol data into the scanner binary so we can validate
    external protocol files without requiring makefile changes. Hat-tip to Pekka
    Paalanen for the embedding trick.
    The embedding trick doesn't work well if the to-be-embedded file is in a
    different location than the source file, so copy/link it during configure and
    then build it in from the local directory.
    
    The current expat parser is not a validating parser, moving scanner.c to
    another parser has the risk of breaking compatibility. This patch adds libxml2
    as extra (optional) dependency, but that also requires parsing the input
    twice.
    
    If the protocol fails validation a warning is printed but no error is returned
    otherwise.
