A bit better documentation of the USB device API, namely
return codes.
Rewrite of usb_generic_handle_packet() to make it more
reable and easier to follow.

QEMU can now automatically grab host USB devices that match the filter.
For now I just extended 'host:X.Y' and 'host:VID:PID' syntax to handle
wildcards. So for example if you do something like
   usb_add host:5.*
QEMU will automatically grab any non-hub device with host address 5.*.

Same with the 'host:PID:*', we grab any device that matches PID.

Filtering itself is very generic so we can probably add more elaborate
syntax like 'host:BUS.ADDR:VID:PID'. So that we can do 'host:5.*:6000:*'.

Anyway, it's implemented using a periodic timer that scans host devices
and grabs those that match the filter. Timer is started when the first
filter is added.

We now keep the list of all host devices that we grabbed to make sure that
we do not grab the same device twice.

btw It's currently possible to grab the same host device more than once.
ie You can just do "usb_add host:1.1" more than once, which of course does
not work. So this patch fixes that issue too.

Along with auto disconnect patch that I send a minute ago the setup is very
seamless now. You can just allocate some usb ports to the VMs and plug/unplug
devices at any time.

I got really annoyed by the fact that you have to manually do
usb_del in the monitor when host device is unplugged and decided
to fix it :)

Basically we now automatically remove guest USB device
when the actual host device is disconnected.

At first I've extended set_fd_handlerX() stuff to support checking
for exceptions on fds. But unfortunately usbfs code does not wake up
user-space process when device is removed, which means we need a
timer to periodically check if device is still there. So I removed
fd exception stuff and implemented it with the timer.

Right now, the Windows build is broken because of NBD.  Using a mingw32 cross
compiler is also badly broken.

This patch fixes the Windows build by stubbing out NBD support until someone
fixes it for Windows.  It also santizing the mingw32 cross compiler support
by replacing the --enable-mingw32 option with a compiler check to determine
if we're on windows or not.

Also remove the weird SDL pseudo-detection for mingw32 using a cross compiler.
The hardcoded sdl-config name is seemly arbitrary.  If you cross compiler SDL
correctly and modify your PATH variable appropriately, it will Just Work when
cross compiling.

The audio driver detection is also broken for cross compiling so you have to
specify the audio drivers explicitly for now.

[ Taking latest isapc changes into account. ]

Ensure that PIC-delivered IRQs are properly de-asserted in case the APIC
is in EXTINT or FIXED mode (with level-triggering selected) on LINT0.
Fixes EFI-BIOS boot issues.

This patch also cleans up a bit the interface between PIC and APIC,
making apic_local_deliver private again.

[ Taking latest isapc changes into account. ]

In case the PIC IRQ gets de-asserted on an isapc machine, we also have
to reset CPU_INTERRUPT_HARD. This is what older qemu (before the
routing-through-APIC changes) used to do as well.

Some headers (e.g. signal.h) include asm/elf.h and the chaos of macro
redefinitions ensues, this kludge avoids it.

Alternative way to fight that would be to change all ELF_XXX and some
other definitions to QEMU_ELF_XXX or something to that effect.

This patch concludes the quest for enabling linux-user on PPC64,
however, since qemu_mallocz uses mmap and, at least on this system,
mmap tends to return values that do not fit into 32bit, emulation for
32bit targets does not work without some hacks wich are to disgusting
to commit (and as `man mmap' tells us MAP_32BIT is only implemented on
X86_64)

p in this case is uint32_t *

e1/e2 are unsigned ints initialized from arithmetics performed on
unsigned longs

The mistake was, probably, never noticed due to the absence of any
big endian linux-user host. The types e1/e2 and p begs the quesiton
why this function takes longs at all.
