On Win32 the setvbuf function requires the last parameter to be size between 2 and INT_MAX bytes, so the calls always failed. Since the whole point of the calls is to set line-buffered mode for the file handle and that's not supported on Win32 anyway, conditionally remove them.

While fixing migration with -S, commit
89befdd1a6 broke the rest of us. Poor
glommer, with a poor family, spare him his life from this monstruosity.
Since the unconditional vm_start, not autostart was the villain, I'm putting
back autostart. Let me know if you prefer other solutions, it doesn't really matter,
doesn't really matter to me.
Any way the wind blows...

Calling gettimeofday() to compute a time interval can cause problems if
the system clock jumps forwards or backwards; replace updtime() with
qemu_get_clock(rt_clock), which calls clock_gettime(CLOCK_MONOTONIC) if
it is available.
Also remove some useless macros.

The UDP emulation code for talk has been commented out since the

user-mode networking can vouch that the special magic (a) is necessary
and (b) works, let's get rid of the code.

We currently use host endian long types to store information
in the dirty bitmap.
This works reasonably well on Little Endian targets, because the
u32 after the first contains the next 32 bits. On Big Endian this
breaks completely though, forcing us to be inventive here.
So Ben suggested to always use Little Endian, which looks reasonable.
We only have dirty bitmap implemented in Little Endian targets so far
and since PowerPC would be the first Big Endian platform, we can just
as well switch to Little Endian always with little effort without
breaking existing targets.
This is the userspace part of the patch. It shouldn't change anything
for existing targets, but help PowerPC.
It replaces my older patch called "Use 64bit pointer for dirty log".

Dirty logs currently get written with native "long" size. On little endian
it doesn't matter if we use uint64_t instead though, because we'd still end
up using the right bytes.
On big endian, this does become a bigger problem, so we need to ensure that
kernel and userspace talk the same language, which means getting rid of "long"
and using a defined size instead.
So I decided to use 64 bit types at all times. This doesn't break existing
targets but will in conjunction with a patch I'll send to the KVM ML make
dirty logs work with 32 bit userspace on 64 kernel with big endian.

This patch addresses the problems found by Andriy Gapon:
- The code was incorrectly overwriting the high order 32
bits of the timer and hpet config registers. This didn't show up
in testing because linux and windows use hpet in legacy mode,
where the high order 32 bits (advertising available interrupts)
of the timer config register are ignored, and the high order 32
bits of the hpet config register are reserved and unused.
- The mask for level-triggered interrupts was off by a bit. (hpet
doesn't currently support level-triggered interrupts).
In addition, I removed some unused #defines, and corrected the ioapic
interrupt values advertised. I'd set this up early in hpet development
and never went back to correct it, and no bugs resulted since linux and
windows use hpet in legacy mode where available interrupts are ignored.

This stores device parameters in a better way than unparsed strings.
New types:
QemuOpt - one key-value pair.
QemuOpts - group of key-value pairs, belonging to one
device, i.e. one drive.
QemuOptsList - list of some kind of devices, i.e. all drives.
Functions are provided to work with these types. The plan is that some
day we will pass around QemuOpts pointers instead of strings filled with
"key1=value1,key2=value2".
Check out the next patch to see all this in action ;)
