Fix compiler warnings
Starting with commit
df7a86ed735eafefbd046c8cad7134652fe3f600,
mingw32 builds result in a compiler warning for dns_addr:
CC slirp/slirp.o
/home/stefan/src/qemu/savannah/qemu/slirp/slirp.c:50: warning: missing braces around initializer
/home/stefan/src/qemu/savannah/qemu/slirp/slirp.c:50: warning: (near initialization for ‘dns_addr.S_un’)
Removing the assignment fixes the warning without the need of special code
for mingw32 (and also saves some bytes in the resulting binary).
To fix another potential compiler warning, the missing 'static'
attribute was added.
The same changes were applied to dns_addr_time.

slirp: Read host DNS config on demand
Currently the qemu user-mode networking stack reads the host DNS
configuration (/etc/resolv.conf or the Windows equivalent) only once
when qemu starts. This causes name lookups in the guest to fail if the
host is moved to a different network from which the original DNS servers
are unreachable, a common occurrence when the host is a laptop.
This patch changes the slirp code to read the host DNS configuration on
demand, caching the results for at most 1 second to avoid unnecessary
overhead if name lookups occur in rapid succession. On non-Windows
hosts, /etc/resolv.conf is re-read only if the file has been replaced or
if its size or mtime has changed.

slirp: Remove our_addr code
Three problems with our_addr:
- It's determined only once when qemu starts, but the address can change
(just like the DNS configuration can).
- It's supposed to be the IP address of a host network interface, but
there's no guarantee that gethostbyname(gethostname()) actually does
that: the host might be a laptop that has only a loopback interface up,
or the hostname might be localhost.localdomain, etc.
- It's useless at best: get_dns_addr() calls it, there's no reason to
send DNS requests to a different IP address if you're running a DNS
server on the host and resolv.conf points to 127.0.0.1.
These problems are easily solved by removing the code.

add qemu_error() + friends
This patch adds some functions for error reporting to address the
problem that error messages should be routed to different destinations
depending on the context of the caller, i.e. monitor command errors
should go to the monitor, command line errors to stderr.
qemu_error() is a printf-like function to report errors.
qemu_errors_to_file() and qemu_errors_to_mon() switch the destination
for the error message to the specified file or monitor. When setting a
new destination the old one will be kept. One can switch back using
qemu_errors_to_previous(). i.e. it works like a stack.
main() calls qemu_errors_to_file(stderr), so errors go to stderr by
default. monitor callbacks are wrapped into qemu_errors_to_mon() +
qemu_errors_to_previous(), so any errors triggered by monitor commands
will go to the monitor.
Each thread has its own error message destination. qemu-kvm probably
should add a qemu_errors_to_file(stderr) call to the i/o-thread
initialization code.

We have already one case in-tree where this is needed:
Try -device virtio-blk-pci (without drive= specified) and watch qemu

fix stack buffer overflows in eepro100.c tx
Hello,
the real world issue is that the hardware allows sends up to 2600 bytes,
and for some reason FreeBSD sometimes sends frames larger than the
ethernet frame size (102+1460 is the maximum I have seen so far),
overflowing the on-stack tx buffer of the driver.
Independent of that, the code should avoid allowing the guest to
overwrite the stack.
This is a minimal patch to fix the issue (you could leave out the size
change of the buf array as well, networking still seems to work either
way). Obviously there are better ways to handle it, but a proper fix IMO
would involve first getting rid of the code duplication and given the
number of patches pending for that code I see no point in working on that now.

virtio-blk: handle NULL returns from bdrv_aio_{read, write}
The bdrv_aio_{read,write} routines can return a NULL pointer when the
I/O submission fails. Currently we ignore this and will wait forever
for an I/O completion and leading to a hang of the guest.
I can easily reproduce this using the native Linux AIO patch, but it's
also possible using normal pthreads-based AIO.

raw-posix: add Linux native AIO support
Now that do have a nicer interface to work against we can add Linux native
AIO support. It's an extremly thing layer just setting up an iocb for
the io_submit system call in the submission path, and registering an
eventfd with the qemu poll handler to do complete the iocbs directly
from there.
This started out based on Anthony's earlier AIO patch, but after
estimated 42,000 rewrites and just as many build system changes
there's not much left of it.
To enable native kernel aio use the aio=native sub-command on the
drive command line. I have also added an option to qemu-io to
test the aio support without needing a guest.

raw-posix: refactor AIO support
Currently the raw-posix.c code contains a lot of knowledge about the
asynchronous I/O scheme that is mostly implemented in posix-aio-compat.c.
All this code does not really belong here and is getting a bit in the
way of implementing native AIO on Linux.
So instead move all the guts of the AIO implementation into
posix-aio-compat.c (which might need a better name, btw).
There's now a very small interface between the AIO providers and raw-posix.c:
- an init routine is called from raw_open_common to return an AIO context
for this drive. An AIO implementation may either re-use one context
for all drives, or use a different one for each as the Linux native
AIO support will do.
- an submit routine is called from the aio_reav/writev methods to submit
an AIO request
There are no indirect calls involved in this interface as we need to
decide which one to call manually. We will only call the Linux AIO native
init function if we were requested to by vl.c, and we will only call
the native submit function if we are asked to and the request is properly
aligned. That's also the reason why the alignment check actually does
the inverse move and now goes into raw-posix.c.
The old posix-aio-compat.h headers is removed now that most of it's
content is private to posix-aio-compat.c, and instead we add a new
block/raw-posix-aio.h headers is created containing only the tiny interface
between raw-posix.c and the AIO implementation.

qcow2: Metadata preallocation
This introduces a qemu-img create option for qcow2 which allows the metadata to
be preallocated, i.e. clusters are reserved in the refcount table and L1/L2
tables, but no data is written to them. Metadata is quite small, so this
happens in almost no time.
Especially with qcow2 on virtio this helps to gain a bit of performance during
the initial writes. However, as soon as create a snapshot, we're back to the
normal slow speed, obviously. So this isn't the real fix, but kind of a cheat
while we're still having trouble with qcow2 on virtio.
Note that the option is disabled by default and needs to be specified
explicitly using qemu-img create -f qcow2 -o preallocation=metadata.
