is given by the field status of sg_io_hdr_t (the value is left shifted

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

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.

Fix some issues with QEMUFile

This patch allows QEMUFile's read and write operations to return
negative error codes.  This is necessary to detect things like closed
streams during live migration.

It also removes unused code for QEMUFileFD write path.  Finally, it
makes sure to avoid attempting to flush an output buffer if the file
is only being used for input.  This was spotted by Uri Lublin.

SH4: Fix swap.b

The SH4 manual documents the swap.b instruction as follows:

        SWAP.B Rm,Rn
                Rm → swap lower 2 bytes → Rn

Current QEMU code, in addition to the above, also clears the high
16 bits. The immediate breakage I saw is that htonl function applied
to  netmask of 255.255.255.0 gives 0, which breaks all networking.
