Update 7.0.11:

    bump to 7.0.11

    Describe what XF86XK_Display does (or now is meant to do).

    Add dead_abovecomma and dead_abovereversedcomma

    Also added aliases dead_psili and dead_dasia.

    The UCS unifies Combining Psili and Combining Dasia with
    Combining Comma Above and Combining Reversed Comma Above.
    These two aliases mirror that unification.

    Comment on the new locations of the files referenced in keysymdef.h
    keysymdef.h has a comment from the monolithic days suggesting that
    the file be kept in sync with mappings inxc/lib/X11/KeyBind.c and
    the protocol specication in xc/doc/specs/XProtocol/X11.keysyms.

    This commit adds pointers to the new locations of those two files.

    Add *~ to .gitignore to skip patch/emacs droppings

    bcopy needs definition in Xfuncs.h for Xming

    Added some more files to .gitignore.

    Enable GCC's visibility attributes on GCC 4 or greater only.

    Add keysym definitions from Jim Gettys.
