Docs on xkbdata vs. xkeyboard-config for modular release

[Alan Coopersmith]

We should include in the modular release documentation some info about
the two sets of XKB data files available and what the differences are.

Unfortunately, I don't know all the details, so I'll suggest some initial
text and hope others can help correct it and flesh it out:

    There are two sources of keyboard configuration data available for the
    X.Org X11R7.0 modular release: xkbdata & xkeyboard-config.

    xkbdata is provided by X.Org and consists of a modular release of the
    keyboard data files from the X11R6.9 monolithic tree.   It is mostly
    compatible with previous releases from X.Org and XFree86 and should
    require little change to most configurations.   However, there is
    currently no maintainer for xkbdata and it is not expected to be
    maintained after the X11R7.0 release.

    xkeyboard-config is provided by the XKeyboardConfig project on
    freedesktop.org <http://www.freedesktop.org/wiki/Software/XKeyboardConfig>.
    It was originally based on the same configuration data files as xkbdata,
    but has undergone extensive work and restructuring, and is actively
    enhanced and maintained.   It contains support for more languages and
    more internet/multimedia extended keyboards, but may require changes
    to the config files of more users as full backwards compatibility has
    not been maintained.

    At this time it is likely that xkbdata will be replaced by
    xkeyboard-config in a future releae of the Xorg modular tree, and
    a number of distros/packagers have already decided to use
    xkeyboard-config in their X11R7.0-based releases of Xorg packages.
