Make using mingw32 on windows fails when running grep "=y$$".
The command is expanded to grep "=y$ and the missing "
results in an error.

I don't expect a file config-devices.mak with =y somewhere in
the middle of a line (they are always at the end of the line),
so simplifying the regular expression to =y seems to be permitted.

This avoids problems with wrong expansion.

Make using mingw32 on windows does not preserve $@ in macros
when they are modified using this pattern:
target: macro += something

This behaviour results in an error when QEMU_CFLAGS containing
"-MMD -MP -MT $@" is modified for compilation of source files
which use SDL: $@ will expand to nothing, -MT no longer has
the correct argument (it will take the next one from the command
line) and the build will fail or run with a wrong command line.

The problem is fixed by using a new macro QEMU_DGFLAGS
which is not modified by a target rule.

A code review run by Steve Grubb complained about code in e1000.c:

In hw/e1000.c at line 89, vlan is declared to be 4 bytes.
At line 382 is an attempt to do a memmove over it with a size of 12.

This was fixed by splitting the memmove in two calls and
adding a comment to the declaration of vlan and data.

While trying to run -kernel with -bios pc-bios/pcbios.bin, I realized
that I was actually writing data to %es, but only set up %ds to a 32-bit
segment we want to write to.

So at the end of the day the data hasn't actually been copied. Oops.

So here's a fix to set ES instead of DS, which makes -kernel work with
BOCHS bios again (and actually makes the code do the correct thing)!

Commit 26a9e82a has the following flaws:

* It enabled DEBUG.

* It referenced two properties by the wrong name in
  usb_host_device_open(), which crashes with "qdev_prop_set: property
  "USB Host Device.bus" not found".

* It broke "-usbdevice host:auto:..." by calling parse_filter()
  incorrectly.

* It broke parsing of "-usbdevice host:BUS.ADDR" and "-usbdevice
  host:VID:PRID" with a trivial pasto.

* It broke wildcards in "-usbdevice host:auto:...".  Before, the four
  filter components were stored as int, and the wildcard was encoded
  as -1.  The faulty commit changed storage to uint32_t, and the
  wildcard encoding to 0.  But it failed to update parse_filter()
  accordingly.

While x86 only needs to sync cr0-4 to know all about its MMU state and enable
qemu to resolve virtual to physical addresses, we need to sync all of the
segment registers on PPC to know which mapping we're in.

So let's grab the segment register contents to be able to use the "x" monitor
command and also enable the gdbstub to resolve virtual addresses.

Currently qcow2 unnecessarily rounds up the length of the backing format string
to the next multiple of 8. At the same time, the array in BlockDriverState can
only hold 15 characters, so in effect backing formats with 9 characters or more
don't work (e.g. host_device).

Save the real string length and things start to work for all valid image format
