qemu_find_file: check name as a straight path even if it has no '/'
Make qemu_find_file() check for the passed in name as a straight
pathname even if it doesn't have any path separator character in it.
This means that "-bios foo", "-dtb foo" etc will find a file 'foo'
in the current directory.
This removes an inconsistency with -kernel and -initrd, which both
accept plain filenames as meaning files in the current directory.
It's also less confusing for the user than an undocumented restriction
that "this option accepts a filename, except for the special case
where the filename you pass happens not to have a '/' in it, in
which case we'll ignore it."

slirp: Ensure smbd and shared directory exist when enable smb
Users may pass the following parameters to qemu:
$ qemu-kvm -net nic -net user,smb= ...
$ qemu-kvm -net nic -net user,smb ...
$ qemu-kvm -net nic -net user,smb=bad_directory ...

failed to start. Users will confuse since samba server
failed silently without any indication of what it did wrong.

if users have permission to access this directory when QEMU's

real sg or scsi-generic via iscsi would work anyway.
Forcing sg also makes qemu skip trying to read from the device to guess
the image format by reading from the device (find_image_format()).
SMC devices do not implement READ6/10/12/16 so it is not possible to
read from them (SSC have different CDBs).
With this patch I can successfully manage a SMC device wiht iscsi in
passthrough mode.
Note, you can currently not boot a qemu guest from a scsi device.
Note,
This only works when the host is linux, since the emulation relies on
definitions of SG_IO from the scsi-generic implementation in the
linux kernel.
It should be fairly easy to re-implement some structures similar enough
for non-linux hosts to do the same style of passthrough via a fake
scsi generic layer and libiscsi if need be.

Exit loop if we have been there too long
Checking each 64 pages is a random magic number as good as any other.
We don't want to test too many times, but on the other hand,
qemu_get_clock_ns() is not so expensive either. We want to be sure
that we spent less than 50ms (half of buffered_file timer), if we
spent more than 100ms, all the accounting got wrong.

Only TCG needs TLB handling
Refactor the code that is only needed for tcg to an static function.
Call that only when tcg is enabled. We can't refactor to a dummy
function in the kvm case, as qemu can be compiled at the same time
with tcg and kvm.

Add spent time for migration
We add time spent for migration to the output of "info migrate"
command. 'total_time' means time since the start fo migration if
migration is 'active', and total time of migration if migration is
completed. As we are also interested in transferred ram when
migration completes, adding all ram statistics
