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.

omap_mpu_state_s::env was renamed to cpu while changing its type.

tb_invalidate_phys_addr has to be called with the exact physical address of
the breakpoint we add/remove, not just the page's base address.
Otherwise we easily fail to flush the right TB.
This breakage was introduced by the commit f3705d5329 "memory: make
phys_page_find() return an unadjusted".
This appeared to work for some guest architectures because their
cpu_get_phys_page_debug implementation returns full translated physical
address, not just the base of the TARGET_PAGE_SIZE-sized page.

dump.c was recently added to the code. It unconditionally
includes sys/procfs which is not available with MinGW (w32, w64).
It looks like this file is not needed at all (tested on Linux),
so I removed it completely.
Some other include statements are also redundant because they are
already included in qemu-common, therefore they were removed, too.

<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 0e82f34d07
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.
