scsi-generic: correct error management
this patch allows to fully use a tape device connected to qemu through
the scsi-generic interface.
Previous patch introduced tape SCSI commands management, this one
improve error case management:
- the SCSI controller command completion must be called with the status
value, not the sense value. In the case of scsi-generic, the SCSI status
is given by the field status of sg_io_hdr_t (the value is left shifted
by one regarding status codes defined in /usr/include/scsi/scsi.h)
- when a read is aborted due to a mark/EOF/EOD/EOM, the len reported to
controller can be 0. LSI controller emulation doesn't know how to manage
this. A workaround found is to call the completion routine with
SCSI_REASON_DONE just after calling it with SCSI_REASON_DATA with len=0.
This patch also manages correctly the block size of the tape device.
This patch has been tested with a real tape device "HP C5683A", linux
guest (debian etch) and tools like "mt", "tar" and "btape".
Windows guest is not better supported than before...

are missing still. This patch enables the use of a recent CPU definition
on 32 bit platforms.
It also fixes two issues that went along the line:
- invalid xlevel in core2duo spec
While looking though the CPUIDs again, I found that xlevel is actually 8.
- non-PSE36 support
The CoreDuo CPUID does not expose the PSE36 capability, but CPUID
0x80000008 is tied to 36 bits. This broke Windows XP installation for
me, so I just set it to 32 bits width when PSE36 is not available. The
original CPU also exposes 32 bit width in CPUID 0x80000008.

Expand cache= option and use write-through caching by default
This patch changes the cache= option to accept none, writeback, or writethough

cache=none has the same behavior as cache=off previously. The later syntax is
still supported by now deprecated. I also cleaned up the O_DIRECT

Introduce a buffered file wrapper for QEMUFile
This patch introduces a buffered QEMUFile wrapper. This allows QEMUFile's to be
rate limited. It also makes it easier to implement a QEMUFile that is
asynchronous since the current QEMUFile API requires that all reads and writes
be synchronous.
The only real non-obvious part of the API is the "frozen" concept. If the
backend returns EAGAIN, the QEMUFile is said to be "frozen". This means no
additional output will be sent to the backend until the file is unfrozen.
qemu_file_put_notify can be used to unfreeze a frozen file.
A synchronous interface is also provided to wait for an unfreeze event. This is
used during the final part of live migration when the VM is no longer running.
