This patch allows to use a "real" SCSI tape with qemu using
"-drive /dev/sgX,if=scsi".

It allows to decode correctly transfer length when the type of the
device is a tape.

Some issues remain when the application reading the tape tries to go
beyond the end of the stream (but they must be corrected at the SCSI
controller level).

This patch refactors the AIO layer to allow multiple AIO implementations.  It's
only possible because of the recent signalfd() patch.  

Right now, the AIO infrastructure is pretty specific to the block raw backend.
For other block devices to implement AIO, the qemu_aio_wait function must
support registration.  This patch introduces a new function,
qemu_aio_set_fd_handler, which can be used to register a file descriptor to be
called back.  qemu_aio_wait() now polls a set of file descriptors registered
with this function until one becomes readable or writable.

This patch should allow the implementation of alternative AIO backends (via a
thread pool or linux-aio) and AIO backends in non-traditional block devices
(like NBD).

Raise UDC (Unexpected Disconnect) when a large enough number of
instructions has been executed by the SCRIPTS processor. This "solution"
is much simpler than temporarily interrupting execution.

This remedies the situation with Windows which downloads SCRIPTS code
that busy loops on guest main memory. Their drivers _do_ handle UDC 
appropriately (at least XP and 2003).

It would be nicer to actually detect infinite loops, but until then,
this bandaid seems acceptable.

Since the situation seems to be rare enough, raise the number 
of instructions to 10000 (previously 1000).

Three people other than myself had success with this patch.
