[PULL] use LRMI for real-mode calls

[Tiago Vignatti]

Keith,

All int10 module went to libx86, which in turn is accessed by a shiny new
lrmi. It became very easy to create real mode contexts now; for instance all X
server code has ~60 lines only. And the cool thing is that the API for drivers
keeps the same: 

    git://people.freedesktop.org/~vignatti/xserver lrmi-for-children
    git://people.freedesktop.org/~vignatti/libx86


and posttool converted to such interface:

     git://people.freedesktop.org/~vignatti/posttool lrmi-for-children


In the library there's some code that I intentionally let away either because
I'm pretty sure it's broken (and I don't have the hardware to test actually)
or because I think it's not needed anymore. We can eventually add though. They
are:

- support generic memory functions: we might need this specialised functions
  to handle access to different types of memory, but for now LRMI doesn't have
  such interface and even doesn't implement a portable way for access "not
  popular" memories.
- non-PC initialization mode (seems to be broken anyway) and int42 
  handling (used only for non-PC)
- int1A handling
- cpu regs emulation capability from x86emu
- video memory mapping and bios reading functions are not portable (we
  probably should move all implementation xf86MapVidMem and xf86ReadBIOS to
  libpciaccess)

I guess also stub functions should be implemented inside libx86 for BSD-like
systems.

Unfortunately no commits here got a review tag. Even so, I'm keeping this work
openly for months already and I'd like to work on it to integrate now. So
please, tell me your thoughts.
