husb: support for USB host device auto connect (Max Krasnyansky)
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.

husb: support for USB host device auto disconnect (Max Krasnyansky)
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.

Fix windows build
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.

Kludge to support linux-user on a PPC64
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)

Set focus to monitor to ask password if line is multiplexed (Laurent Vivier)
This patch allows to display the "Password:" prompt if we use encrypted
disk with "-nographic" option.
It also modifies management of "-nographic" to not override user's
choices for "-serial", "-parallel" and "-monitor".
When qemu has to ask a password with "-nographic" with a multiplexed
serial interface, it forces the focus to the monitor and restore
original focus after.

Avoids nasty warnings about flush_icache_range from gcc4 and inability
to compile [cpu-]exec.c with gcc3 and -O, also the function is much

This patch moves the pty char device imlementation away from the generic
filehandle code. It tries to detect as good as possible whenever there
is someone connected to the slave pty device and only send data down the
road in case someone is listening. Unfortunaly we have to poll via
timer once in a while to check the status because we have to use read()
on the master pty to figure the status (returns -EIO when unconnected).
Poll intervall for an idle guest is one second, when the guest sends
data to the virtual device linked to the pty we check more frequently.
The point for all of this is to avoid qemu blocking and not responding
any more. Writing to the master pty handle succeeds even when nobody is
connected to (and reading from) to the slave end of the pty. The kernel
just bufferes the writes. And as soon as the kernel buffer is full the
write() call blocks forever ...
That should teach one to not blindly trust documentation that will
(out of the blue) use decimal and binary representation for numbers in
the same chart for no apparent reason and without any prefixes, sigh..
