Delete time-traveling multiple personality disorder from the server.

Gaetan notes:

    There were a couple of drivers containing an unknown version of the
    modes/parser code. This was done in server 1.2 time frame because it
    was released without mode code. It was barely or not maintained
    afterwards. There are currently no video drivers with a copy of the
    modes code.

Most of these ifdefs were introduced in commit
a8d760f5

, where Aaron wrote,

    This change uses XORG_VERSION_CURRENT < 7.0 to mean "server newer
    than 1.2" since XORG_VERSION current went backwards at some point.

Alan explains that:

    In Xorg 1.3, when we first released an Xorg server release decoupled
    from the katamari release schedule.  (1.0 through 1.2 were released
    as part of X11R7.0 through 7.2, while 1.3 came out between X11R7.2 &
    7.3.)
