[PATCH] Remove hw/xfree86/os-support/misc/{Delay.c,BUSmemcpy.c}

[Matt Turner]

Hi,

The attached patches kill off unused code in hw/xfree86/os-support/misc/.

The first patch removes Delay.c. Delay.c provides a single function,
xf86UDelay. It is unused inside the xserver, and I cannot find any
modules on my system that use it. Plus, does the xserver /really/ need
to provide a wrapper for usleep for you?

The second patch removes BUSmemcpy.c. BUSmemcpy.c provides
xf86BusToMem and xf86MemToBus, which are are memcpy wrappers written
to avoid glibc's memcpy on Alpha. glibc'c memcpy on Alpha has improved
much since this was written, so it's no longer needed. Neither
function is used inside the xserver, and no module on my machine uses
either as well.

Sorry for the attachments. I'll learn to use git properly before
sending in the future.

Thanks,

Matt Turner
