    Allow using XV and RandR rotation simultaneously.
    
     As it doesn't seem feasible to rotate the video, I did some modifications
    at SMI_PutImage and SMI_ClipVideo to make PutImage work (incorrectly) with
    rotation enabled. The image is displayed unrotated.

    Some fixes in the EXA UTS/DTS code.
    
     In DTS:
      * It uses the screen Bpp inestead of the pixmap Bpp...
        this gives some problems when using pixmaps with different depth
        to the screen.
     In UTS:
      * aligned_pitch was computed from src_pitch inestead of the
        pixmap width.
      * When writing the target coordinates to the DE registers, it does
        y*0xFFFF inestead of y & 0xFFFF.
      * I renamed source_pitch to src_pixelpitch as it is very confusing
        to have src_pitch and source_pitch.
      * It isn't necessary to call WaitQueue before copying each scanline,
        but it seems it almost doesn't affect performance.

commit 209097ba5b44a0ce0da7f1ea52150dcace2b5244

    RandR rotation implemented.
    
    * I added the configuration file option "RandRRotation".
    * I replaced pSmi->ShadowPitch with pSmi->screenStride, it seems it
       makes more sense because the lower word of ShadowPitch may change
       independently.
    * I moved the SMI_DEDataFormat to smi_accel.c because it seems it is
      a piece of code repeated many times in the driver.
    * At some places, it is assumed the framebuffer is at FBOffset:
      when using a shadow framebuffer, FBOffset is the location of the
      on-screen framebuffer (0 should be used). This made e.g. EXA
      completly useless with ShadowFB enabled (it crashed).
    * In the FBManager initialization, I have replaced xf86InitFBManager
      with xf86InitFBManagerRegion to reserve some additional space as
      screen fb: it's unlikely to be the case, but a less efficient
      alignment in the rotated mode could make the rotated mode need more
      memory than the unrotated one.
      This is not a problem with EXA as the offscreen memory parameters
      can be easily modified when doing the rotation.
    * In SMI_RefreshArea it's assumed that some DE registers are already
      in some state, this is specially not true when using EXA.
    * SMI_ValidMode rejects a rotated mode with different dimensions
      than the panel. This seems to work now.

    Updates in SMI_EnterVT when remapping memory.
    
      Update the screen pixmap header with the new aperture address
    when remapping framebuffer memory in SMI_EnterVT.
      Update pSmi->EXADriverPtr->memoryBase too, in case EXA is
    being used.

    Memory detection moved before memory mapping in SMI_PreInit.
    
    Take into account the VideoRam configuration option.
