99123e139d configure: add --version flag
Standard autoconf scripts include a --version flag so people can easily
query things.  Add this to qemu's configure so it too can integrate with
build systems that have standard autotool helpers.

Comment for "return consistent self-powered state":

the Configuration Descriptor bmAttributes claims we are self powered,
but we were returning not self powered to USB_REQ_GET_STATUS control message.

In practice, this message is not sent by a linux 2.6.35.10-74.fc14.x86_64
guest (not tested on other guests), unless you issue lsusb -v as root (for
example).

39ac845510 Implement hcall based RTAS for pSeries machines
On pSeries machines, operating systems can instantiate "RTAS" (Run-Time
Abstraction Services), a runtime component of the firmware which implements
a number of low-level, infrequently used operations.  On logical partitions
under a hypervisor, many of the RTAS functions require hypervisor
privilege.  For simplicity, therefore, hypervisor systems typically
implement the in-partition RTAS as just a tiny wrapper around a hypercall
which actually implements the various RTAS functions.

This patch implements such a hypercall based RTAS for our emulated pSeries
machine.  A tiny in-partition "firmware" calls a new hypercall, which
looks up available RTAS services in a table.

cc4e8741cc rbd: don't link with -lcrypto
rbd support tries to both link with -lrados and -lcrypto. While the
first one is of course necessary, the second is not necessary (only
librados ifself needs to link with libcrypto).

This fixes a licensing issue: qemu as a whole is GPL v2, and thus can't
be linked with OpenSSL without an exception in the license, which seems
difficult to get given the number of persons involved.

71deff2749 target-i386: set target_phys_bits to 64
qemu i386 used to support more than 4GB of RAM through PAE, but it has
been disabled for an unknown reason. Reenable it.

Note that simply running qemu x86_64 and emulating a 32-bit CPU is not
a solution to this problem as it is about 15% slower (it needs to
emulate 64 bit registers even if half of them are not used). On the
other hand, I haven't seen any measurable impact by switching
target_phys_bits to 64.

de758970b6 kvm: Fix race between timer signals and vcpu entry under !IOTHREAD
Found by Stefan Hajnoczi: There is a race in kvm_cpu_exec between
checking for exit_request on vcpu entry and timer signals arriving
before KVM starts to catch them. Plug it by blocking both timer related
signals also on !CONFIG_IOTHREAD and process those via signalfd.

As this fix depends on real signalfd support (otherwise the timer
signals only kick the compat helper thread, and the main thread hangs),
we need to detect the invalid constellation and abort configure.

b3d08c029d Add a DTrace tracing backend targetted for SystemTAP compatability
This introduces a new tracing backend that targets the SystemTAP
implementation of DTrace userspace tracing. The core functionality
should be applicable and standard across any DTrace implementation
on Solaris, OS-X, *BSD, but the Makefile rules will likely need
some small additional changes to cope with OS specific build
requirements.

This backend builds a little differently from the other tracing
backends. Specifically there is no 'trace.c' file, because the
'dtrace' command line tool generates a '.o' file directly from
the dtrace probe definition file. The probe definition is usually
named with a '.d' extension but QEMU uses '.d' files for its
external makefile dependancy tracking, so this uses '.dtrace' as
the extension for the probe definition file.

The 'tracetool' program gains the ability to generate a trace.h
file for DTrace, and also to generate the trace.d file containing
the dtrace probe definition.

Example usage of a dtrace probe in systemtap looks like:

  probe process("qemu").mark("qemu_malloc") {
    printf("Malloc %d %p\n", $arg1, $arg2);
  }

* .gitignore: Ignore trace-dtrace.*
* Makefile: Extra rules for generating DTrace files
* Makefile.obj: Don't build trace.o for DTrace, use
  trace-dtrace.o generated by 'dtrace' instead
* tracetool: Support for generating DTrace data files
