Here comes a new patch
- make sure ERESTARTSYS will always be propagated
- ReleaseBitmap: starting with Firmware 261e, also release when
- removes unused #define BMP_LOADINGS
- in many cases changed the return value from -1 to something more
  meaningful like ETIMEDOUT, EINVAL
- changed syslog message timeout waiting for COMMAND such that it 
  indicates what command did not complete
- reduce # of arguments for LoadBitmap and BlitBitmap
- av7110_osd_cmd: remove the out: label
