  Added files:

    sys/i386/linux       linux_support.s 
  Log:
  Move futex support code from <arch>/support.s into linux compat directory.
  Implement all futex atomic operations in assembler to not depend on the
  fuword() that does not allow to distinguish between -1 and failure return.
  Correctly return 0 from atomic operations on success.
