2d16c8e988 configure: Detect uuid on MacOSX (fixes compile failure)
Commit 7791dba3ec broke compilation on MacOSX, because it introduced
a new include of util.h. On MacOSX this includes pwd.h which in turn
includes the system uuid/uuid.h, which causes a compile failure if
QEMU was configured without CONFIG_UUID due to a conflict between
the system header and our fallback versions:
  block/vdi.c:124:20: error: static declaration of 'uuid_generate'
  follows non-static declaration
  static inline void uuid_generate(uuid_t out)
                     ^
  /usr/include/uuid/uuid.h:63:6: note: previous declaration is here
  void uuid_generate(uuid_t out);
       ^

Fix this breakage by improving configure's check for uuid to work on
MacOSX (where there is no need to link in a separate libuuid).

Note that if the user explicitly runs configure with '--disable-uuid'
on MacOSX then QEMU will fail to compile.

3556c233d9 qom: allow turning cast debugging off
Cast debugging can have a substantial cost (20% or more).  Instead of adding
special-cased "fast casts" in the hot paths, we can just disable it in
releases.  The tracing facilities we just added make it easier to analyze
those problems that cast debugging would reveal.

8e515b125d configure: Check that "libtool" is not the MacOSX one
The "libtool" binary on MacOSX is not GNU libtool, and doesn't support
anything like the same set of command line options. Test whether we
have accidentally picked this up (by looking for whether it handles
the GNU --version switch), and discard it if so. The fallback machinery
for the "we don't have a libtool" case will work fine. This fixes a
failure in "make install" on MacOSX.

781e9545db trace: Add ftrace tracing backend
This patch adds a ftrace tracing backend which sends trace event to
ftrace marker file. You can effectively compare qemu trace data and
kernel(especially, kvm.ko when using KVM) trace data.
The ftrace backend is restricted to Linux only.

To try out the ftrace backend:

 $ ./configure --trace-backend=ftrace
 $ make

if you use KVM, enable kvm events in ftrace:

 # sudo echo 1 > /sys/kernel/debug/tracing/events/kvm/enable

After running qemu by root user, you can get the trace:

 # cat /sys/kernel/debug/tracing/trace

libssh2 >= 1.2.8 is required to enable this block device (because
that version introduced the libssh2_session_handshake call).

Change the test to use pkg-config exclusively.  If the user requests

following error is displayed:

  $ ./configure --enable-libssh2

  ERROR: libssh2 >= 1.2.8 required for --enable-libssh2

5e9be92d77 vhost-scsi: new device supporting the tcm_vhost Linux kernel module
The WWPN specified in configfs is passed to "-device vhost-scsi-pci".
The tgpt field of the SET_ENDPOINT ioctl is obsolete now, so it is not
available from the QEMU command-line.  Instead, I hardcode it to zero.

Changes in Patch-v2:
   - Add vhost_scsi_get_features() in order to determine feature bits
     supports by host kernel (mst + nab)
   - Re-enable usage of DEFINE_VIRTIO_COMMON_FEATURES, and allow
     EVENT_IDX to be disabled by host in vhost_scsi_get_features()
   - Drop unused hotplug bit in DEFINE_VHOST_SCSI_PROPERTIES

Changes in Patch-v1:
   - Set event_idx=off by default (nab, thanks asias)
   - Disable hotplug feature bit for v3.9 tcm_vhost kernel code, need to
     re-enable in v3.10 (nab)
   - Update to latest qemu.git/master HEAD

Changes in WIP-V3:
   - Drop ioeventfd vhost_scsi_properties (asias, thanks stefanha)
   - Add CONFIG_VHOST_SCSI (asias, thanks stefanha)
   - Add hotplug feature bit

Changes in WIP-V2:
   - Add backend guest masking support (nab)
   - Bump ABI_VERSION to 1 (nab)
   - Set up set_guest_notifiers (asias)
   - Set up vs->dev.vq_index (asias)
   - Drop vs->vs.vdev.{set,clear}_vhost_endpoint (asias)
   - Drop VIRTIO_CONFIG_S_DRIVER check in vhost_scsi_set_status (asias)

Howto:
   Use the latest seabios, at least commit b44a7be17b
   git clone git://git.seabios.org/seabios.git
   make
   cp out/bios.bin /usr/share/qemu/bios.bin

a540f158db configure/Make: Build libfdt from submodule DTC
Configure to use the DTC submodule to build libfdt when no system libfdt
is found. Prompt to install the DTC submodule if --enable-fdt is set but
no DTC can be found.

DTC has no out-of-tree build capability, so the configure will symlink
the Makefile and scripts directory in the out of tree build directory
and pass in all the needed DTC arguments to make out of tree build happen.
Ideally we fix the DTC make to support out of tree, but did it this way to
avoid commits to DTC.

2b2325ff64 use libusb for usb-host
Reimplement usb-host on top of libusb.
Reasons to do this:

 (1) Largely rewritten from scratch, nice opportunity to kill historical
     cruft.
 (2) Offload usbfs handling to libusb.
 (3) Have a single portable code base instead of bsd + linux variants.
 (4) Bring usb-host support to any platform supported by libusbx.

For now this goes side-by-side to the existing code.  That is only to
simplify regression testing though, at the end of the day I want remove
the old code and support libusb exclusively.  Merge early in 1.5 cycle,
remove the old code after 1.5 release or something like this.

Thanks to qdev the old and new code can coexist nicely on linux.  Just
use "-device usb-host-linux" to use the old linux driver instead of the
libusb one (which takes over the "usb-host" name).

The bsd driver isn't qdev'ified so it isn't that easy for bsd.
I didn't bother making it runtime switchable, so you have to rebuild
qemu with --disable-libusb to get back the old code.

0a12ec87a5 block: Add support for Secure Shell (ssh) block device.
qemu-system-x86_64 -drive file=ssh://hostname/some/image

QEMU will ssh into 'hostname' and open '/some/image' which is made
available as a standard block device.

You can specify a username (ssh://user@host/...) and/or a port number
(ssh://host:port/...).  You can also use an alternate syntax using
properties (file.user, file.host, file.port, file.path).

Current limitations:

- Authentication must be done without passwords or passphrases, using
  ssh-agent.  Other authentication methods are not supported.

- Uses a single connection, instead of concurrent AIO with multiple
  SSH connections.

This is implemented using libssh2 on the client side.  The server just
requires a regular ssh daemon with sftp-server support.  Most ssh
daemons on Unix/Linux systems will work out of the box.

c30d1aea14 cpu-exec: Allow "-d exec" in non-debug builds (drop CONFIG_DEBUG_EXEC)
The CONFIG_DEBUG_EXEC define compiles out a single qemu_log_mask()
call, which is a pretty trivial cost even for something in the main
cpu_exec() loop.  Having this be conditionally defined means that
'-d exec' on a non-debug build will silently do nothing.  Drop the
define and the configure machinery that sets it, in favour of just
always allowing this log option to be enabled at runtime.  As a
concession to the mainloopiness, we use qemu_loglevel_mask()+qemu_log()
rather than qemu_log_mask() to avoid the function call overhead.

Note that DEBUG_DISAS is always defined, so removing the
'|| defined(CONFIG_DEBUG_EXEC)' from those conditionals makes
no behavioural change for that logging.

7c2acc7062 configure: Don't fall back to gthread coroutine backend
The gthread coroutine backend is broken and does not produce a working
QEMU; it is only useful for some very limited debugging situations.
Clean up the backend selection logic in configure so that it now runs
"if on windows use windows; else prefer ucontext; else sigaltstack".

To do this we refactor the configure code to separate out "test
whether we have a working ucontext", "pick a default if user didn't
specify" and "validate that user didn't specify something invalid",
rather than having all three of these run together. We also simplify
the Makefile logic so it just links in the backend the configure
script selects.

76ad07a493 configure: Provide and use convenience error reporting function
Provide a convenience function for reporting an error and exiting,
and update various places in the configure script to use it.
This allows us to be a little more consistent about how format
our error messages and makes the calling code shorter.

5e3a0f418c w32: Fix build with older gcc (unresolved symbol)
The cross i586-mingw32msvc-gcc 4.4.4 from Debian Squeeze does not support
__sync_val_compare_and_swap by default.

Using -march=i686 fixes that and should also result in better code.

b1e5fff4af configure: rename OpenGL feature to GLX
As the probe now actually checks for the availability of GLX, rename it
accordingly. The only user of this feature is the milkymist-tmu2 model.
