There are two different syscall names for the same goal.
On systems with sizeof(long) == 64 it calls newfstatat.
On systems with sizeof(long) == 32 it calls fstatat64.

rdra and tdra are already kept converted in the pcnet state structure.
Avoid converting derivatives a second time. The same case with the local
variable xmit_cxda: it already contains a converted cxda address. This
issue only causes troubles when using the pcnet in 16-bit legacy mode.

The sys_inotify* calls are defined if the target supports them and the
host supports the necessary syscalls. But the syscalls are handled if
the target supports them. This situation leads to compilation failures
when the host doesn't support the necessary syscalls, as the linker will
complain about undefined functions.
Fix this state of affairs by making the handling conditions the same as
the call definition conditions.

The vga screen dump function updates last_width and last_height,
but does not change the DisplaySurface that these variables describe.
A consequent vga_draw_graphic() will therefore fail to resize the
surface and crash.
Fix by invalidating the display state after a screen dump, forcing
vga_draw_graphic() to reallocate the DisplaySurface.

In vnc.c in pixel_format_message, the code tries to clear the
QEMU_ALLOCATED_FLAG from the client display surface, however
it uses the wrong operator and ends up enabling all other
flags. Most notably this enables the big endian flag and
causes some chaos.

Make all AIO requests vectored and defer linearization until the actual
I/O thread. This prepares for using native preadv/pwritev.
Also enables asynchronous direct I/O by handling that case in the I/O thread.
Qcow and qcow2 propably want to be adopted to directly deal with multi-segment
requests, but that can be implemented later.

The beginning of the register allocation order list on the TCG x86_64
target matches the list of clobbered registers. This means that when an
helper is called, there is almost always clobbered registers that have
to be spilled.
The same way register %rsi and %rdi are at the top of the register
allocation order list, while they can't be used for load/store
operations. This means the data and/or address registers are very often
%rsi and %rdi, and their values have to be spilled, and then moved back
to another register.
This patches changes to the allocation order to avoid those effects.
It results in a 8% gain speed in qemu-x86_64 to compress a bzip2 file,
and a 6% gain in qemu-system-mips64 to compile a small application.
