565465fcae slirp: Put forked exec into separate process group
Recent smb daemons tend to terminate themselves via a process group
SIGTERM. If the daemon is still in qemu's group by that time, qemu will
die as well. Avoid this by always pushing fork_exec processes into a
group of their own, not just (unused) type 2 execs.

c54ed5bcdd slirp: Canonicalize restrict syntax
All other boolean arguments accept on|off - except for slirp's restrict.
Fix that while still accepting the formerly allowed yes|y|no|n, but
reject everything else. This avoids accidentally allowing external
connections because syntax errors were so far interpreted as
'restrict=no'.

12b513d837 slirp: Fix restricted mode
This aligns the code to what the documentation claims: Allow everything
but requests that would have to be routed outside of the virtual LAN.

So we need to drop the unneeded IP-level filter, allow TFTP requests,
and add the missing protocol-level filter to ICMP.

9052ea6bf4 Generalize -machine command line option
-machine somehow suggests that it selects the machine, but it doesn't.
Fix that before this command is set in stone.

Actually, -machine should supersede -M and allow to introduce arbitrary
per-machine options to the command line. That will change the internal
realization again, but we will be able to keep the user interface
stable.

69354a8334 USB: add usb network redirection support
This patch adds support for a usb-redir device, which takes a chardev
as a communication channel to an actual usbdevice using the usbredir protocol.

Compiling the usb-redir device requires usbredir-0.3 to be installed for
the usbredir protocol parser, usbredir-0.3 also contains a server for
redirecting usb traffic from an actual usb device. You can get the 0.3
release of usbredir here:
http://people.fedoraproject.org/~jwrdegoede/usbredir-0.3.tar.bz2
(getting a more formal site for it is a WIP)

Example usage:
1) Start usbredirserver for a usb device:
sudo usbredirserver 045e:0772
2) Start qemu with usb2 support + a chardev talking to usbredirserver +
   a usb-redir device using this chardev:
qemu ... \
  -readconfig docs/ich9-ehci-uhci.cfg \
  -chardev socket,id=usbredirchardev,host=localhost,port=4000 \
  -device usb-redir,chardev=usbredirchardev,id=usbredirdev

d1afc48b7c SPARC64: implement addtional MMU faults related to nonfaulting load
This patch implements MMU faults caused by TTE.NFO and TTE.E:
- access other than nonfaulting load to a page marked NFO should
  raise data_access_exception
- nonfaulting load to a page marked with E bit should raise
  data_access_exception

To distinguish nonfaulting loads, this patch extends (abuses?) the rw
argument of get_physical_address_data().  rw is set to 4 on nonfaulting
loads.

agent:

guest-sync

guest-shutdown
guest-file-open
guest-file-read
guest-file-write
guest-file-seek
guest-file-flush
guest-file-close
guest-fsfreeze-freeze
guest-fsfreeze-thaw
guest-fsfreeze-status

The input/output specification for these commands are documented in the
schema.

Example usage:

  host:

         -chardev socket,path=/tmp/vs0.sock,server,nowait,id=qga0 \
         -device virtserialport,chardev=qga0,name=org.qemu.quest_agent.0

Is equivalent to:

e18df14185 Add hard build dependency on glib
GLib is an extremely common library that has a portable thread implementation
along with tons of other goodies.

GLib and GObject have a fantastic amount of infrastructure we can leverage in
QEMU including an object oriented programming infrastructure.

Short term, it has a very nice thread pool implementation that we could leverage
in something like virtio-9p.  It also has a test harness implementation that
this series will use.

This will cause a build error when files including error.h

because the only file including it is json-parser.h and it does
include qemu-common.h, but let's get it fixed.

5c0263204d Introduce compiler.h header file
This moves compiler related macros from qemu-common.h to compiler.h.

The reason for this change is that there are simple header files that
depend only on the compiler macros, so including qemu-common.h is overkill.

Besides, qemu-common.h is bloated and will benefit from some splitting.

Please, also note that the QEMU_BUILD_BUG_ON() macro is being fixed to
not use double underscores as a prefix and the license text was added
by Vassili Karpov (malc), who is one of the authors of the new file.
