qemu-iotests: fill streaming test image with data
The TestStreamStop test case is racy; if the job completes before we can
cancel it, it fails. If we remove the sleep the job will be canceled
before it has even started, and the test succeeds but it is also not
testing anything interesting.
But if the image is left sparse, then the job has really nothing to do.
For qcow2 it will read one L2-table, for raw it will issue a bunch of
ioctls. This also falls under "not testing anything interesting", and
this may be happening right now (depending on the filesystem) since the
file protocol got an is_allocated method.
Filling the test image with data ensures that the test covers the
intended case. It also slows down the test, which will be particularly
important after the next patch.

kvm: i8254: Fix conversion of in-kernel to userspace state
Due to a offset between the clock used to generate the in-kernel
count_load_time (CLOCK_MONOTONIC) and the clock used for processing this
in userspace (vm_clock), reading back the output of PIT channel 2 via
port 0x61 was broken. One use cases that suffered from it was the CPU
frequency calibration of SeaBIOS, which also affected IDE/AHCI timeouts.
This fixes it by calibrating the offset between both clocks on
kvm_pit_get and adjusting the kernel value before saving it in the
userspace state. As the calibration only works while the vm_clock is
running, we cache the in-kernel state across stopped phases.

do not include <libutil.h> needlessly or if it doesn't exist
<libutil.h> and <util.h> on *BSD (some have one, some another)
were #included just for openpty() declaration. The only file
where this function is actually used is qemu-char.c.
In vl.c and net/tap-bsd.c, none of functions declared in libutil.h
(login logout logwtmp timdomain openpty forkpty uu_lock realhostname
fparseln and a few others depending on version) are used.
Initially the code which is currently in qemu-char.c was in vl.c,
it has been removed into separate file in commit
0e82f34d077dc2542
Fri Oct 31 18:44:40 2008, but the #includes were left in vl.c.
So with vl.c, we just remove includes - libutil.h, util.h and
pty.h (which declares only openpty() and forkpty()) from there.
The code in net/tap-bsd.c, which come from net/tap.c, had this

net: split all the tap code out into net/tap.c
Note this commit not only moved stuff out of net.c to net/tap.c,
but also rewrote large portions of the tap code, and added these
completely unnecessary #includes -- as usual, I question why such
a misleading commit messages are allowed.
Again, no functions defined in libutil.h or util.h on *BSD are
used by neither net/tap.c nor net/tap-bsd.c. Removing them.
And finally, the only real user for these #includes, qemu-char.c,
which actually uses openpty(). There, the #ifdef logic is wrong.
A GLIBC-based system has <pty.h>, even if it is a variant of *BSD.
So __GLIBC__ should be checked first, and instead of trying to
include <libutil.h> or <util.h>, we include <pty.h>. If it is not
GLIBC-based, we check for variations between <*util.h> as before.
This patch fixes build of qemu 1.1 on Debian/kFreebsd (well, one
of the two problems): it is a distribution with a FreeBSD kernel,
so it #defines at least __FreeBSD_kernel__, but since it is based
on GLIBC, it has <pty.h>, but current version does not have neither
<util.h> nor <libutil.h>, which the code tries to include 3 times
but uses only once.
