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...

i386/SVM: return amount of ASIDs
With SVM the TLB supports tagging to distinguish TLB entries from
different virtual CPUs. This tag is called an ASID. The amount of ASIDs is
given in EBX of the SVM-CPUID-leaf. Currently we return 0, which might
break hypervisors. Let's better return something >0 here, say 0x10.
Since we're flushing the complete TLB on every VM entry and exit we're not
making use of the ASID information anyways.

target-i386: Add Core Duo Definition
This patch adds a CPU definition for the Core Duo CPU. I tried to
resemble the original as closely as possible and document what features
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.

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.

Increase write buffer size in pflash emulation (Thomas Petazzoni).
The current flash emulation code advertises a write buffer size of 16
bytes (1 << 4, according to offset 0x2A of the CFI table). This is
very small compared to normal write buffer sizes, and makes the
process of writing to the flash very slow (at least from U-Boot).
This patch increases this size to 2048 bytes. Except the modification
of the CFI table, the only other required modification is to use
"value" instead of "cmd" to set pfl->counter, because cmd is truncated
to the 8 lower bits of value, while the number of bytes for a write
can now be greater than 255 bytes.
