These include files don't exist for MinGW and are not needed for Linux
(and hopefully for other hosts as well), so remove them.

Commit 0b516ef0dfad9a7b34c675c98e8ec92ab4d38466 added version.o to all
executables, but broke out-of-tree builds: for those builds the pattern
rule %.o: %.rc from rules.mak does not match, so version.o was no longer
built.
Adding explicit build rules fixes this.

descriptor table
virtqueue_get_avail_bytes: when found a indirect desc, we need loop over it.
/* loop over the indirect descriptor table */
indirect = 1;
max = vring_desc_len(desc_pa, i) / sizeof(VRingDesc);
num_bufs = i = 0;
desc_pa = vring_desc_addr(desc_pa, i);
But, It init i to 0, then use i to update desc_pa. so we will always get:
desc_pa = vring_desc_addr(desc_pa, 0);
the last two line should swap.

All callers always use the same values (get_system_memory(),
get_system_io()), so the parameters are pointless.
If one day we decide to eliminate get_system_memory() and
get_system_io(), we will be able to do that more easily by adding the
values to struct QEMUMachineInitArgs.

Making the older compat functions call the newer compat functions at the
beginning allows the older functions undo what's done by newer compat
functions. e.g.: pc_compat_1_4() will be able to call pc_compat_1_5()
and then set has_pvpanic=false.

The pc_init_pci_1_2()/pc_init_pci_1_0() split was made on commit
6fd028f64f662c801fd5a54d0e3a1d2baeee93ea, in preparation for commit
9953f8822cc316eec9962f0a2858c3439a80adec. The latter was reverted, so there's
no reason to keep two separate functions that do exactly the same, anymore.

ROM files that are put in FW CFG are copied to guest ram, by BIOS, but
they are not backed by RAM so they don't get migrated.
Each time we change two bytes in such a ROM this breaks cross-version
migration: since we can migrate after BIOS has read the first byte but
before it has read the second one, getting an inconsistent state.
Future-proof this by creating, for each such ROM,
an MR serving as the backing store.
This MR is never mapped into guest memory, but it's registered
as RAM so it's migrated with the guest.
Naturally, this only helps for -M 1.7 and up, older machine types
will still have the cross-version migration bug.
Luckily the race window for the problem to trigger is very small,
which is also likely why we didn't notice the cross-version
migration bug in testing yet.

Migration code assumes that each MR is a multiple of TARGET_PAGE_SIZE:
MR size is divided by TARGET_PAGE_SIZE, so if it isn't migration
never completes.
But this isn't really required for regions set up with
memory_region_init_ram, since that calls qemu_ram_alloc
which aligns size up using TARGET_PAGE_ALIGN.
Align MR size up to full target page sizes, this way
migration completes even if we create a RAM MR
which is not a full target page size.

Indeed, remove it entirely and remove the is_tcg_gen_code check
from GETPC_EXT.
Fixes https://bugs.launchpad.net/qemu/+bug/1218098 wherein a call
to a "normal" helper function performed a sequence of tail calls
all the way into the memory helper functions, leading to a stack
frame in which the memory helper function appeared to be called
directly from tcg.

Avoid a loop in the tlb_fill path; the fill will either succeed or
generate an exception.
Inline the slow_ld/st function; it was a complete copy of the main
helper except for the actual cross-page unaligned code, and the
compiler was inlining it anyway.
Add unlikely markers optimizing for the most common case of simple
tlb miss.
Make sure the compiler can optimize away the unaligned paths for a
1 byte access.

Notify all timerlists derived from vm_clock in icount warp
calculations.
When calculating timer delay based on vm_clock deadline, use
all timerlists.
For compatibility, maintain an apparent bug where when using
icount, if no vm_clock timer was set, qemu_clock_deadline
would return INT32_MAX and always set an icount clock expiry
about 2 seconds ahead.
NB: thread safety - when different timerlists sit on different
threads, this will need some locking.

On qemu_mod_timer_ns, ensure qemu_notify or aio_notify is called to
end the appropriate poll(), irrespective of use_icount value.
On qemu_clock_enable, ensure qemu_notify or aio_notify is called for
all QEMUTimerLists attached to the QEMUClock.

Convert mainloop to use timeout from default timerlist group
(i.e. the current 3 static timers)
main-loop.c produces a (possibly spurious) warning about
multiple iterations. Adapt the way this works for a signed
timeout and make the warning a bit safer.

Convert aio_poll to use deadline based on AioContext's timers.
aio_poll has been changed to return accurately whether progress
has occurred. Prior to this commit, aio_poll always returned
true if g_poll was entered, whether or not any progress was
made. This required a change to tests/test-aio.c where an
assert was backwards.
