Tomoki Sekiyama b39297aedf qemu-ga: Add Windows VSS provider and requester as DLL
Adds VSS provider and requester as a qga-vss.dll, which is loaded by
Windows VSS service as well as by qemu-ga.

"provider.cpp" implements a basic stub of a software VSS provider.
Currently, this module only relays a frozen event from VSS service to the
agent, and thaw event from the agent to VSS service, to block VSS process
to keep the system frozen while snapshots are taken at the host.

To register the provider to the guest system as COM+ application, the type
library (.tlb) for qga-vss.dll is required. To build it from COM IDL (.idl),
VisualC++, MIDL and stdole2.tlb in Windows SDK are required. This patch also
adds pre-compiled .tlb file in the repository in order to enable
cross-compile qemu-ga.exe for Windows with VSS support.

"requester.cpp" provides the VSS requester to kick the VSS snapshot process.
Qemu-ga.exe works without the DLL, although fsfreeze features are disabled.

These functions are only supported in Windows 2003 or later. In older
systems, fsfreeze features are disabled.

In several versions of Windows which don't support attribute
VSS_VOLSNAP_ATTR_NO_AUTORECOVERY, DoSnapshotSet fails with error
VSS_E_OBJECT_NOT_FOUND. In this patch, we just ignore this error.
To solve this fundamentally, we need a framework to handle mount writable
snapshot on guests, which is required by VSS auto-recovery feature
(cleanup phase after a snapshot is taken).

Stefan Weil 0b516ef0df w32: Add missing version.o to all executables (fix regression)
QEMU executables for w32, w64 had included meta information built from
version.rc. These rules were changed several times some months ago.

The latest version added version.o to the tools, but not to the system
emulations.

This patch adds the meta information to all system emulations again.

Eduardo Habkost 8e8aba5054 target-i386: Add "feature-words" property to X86CPU
This property will be useful for libvirt, as libvirt already has logic
based on low-level feature bits (not feature names), so it will be
really easy to convert the current libvirt logic to something using the
"feature-words" property.

The property will have two main use cases:
 - Checking host capabilities, by checking the features of the "host"
   CPU model
 - Checking which features are enabled on each CPU model

Example output:

  $ ./QMP/qmp --path=/tmp/m \
    qom-get --path=/machine/icc-bridge/icc/child[0] \

Paolo Bonzini bdee56f546 tpm: reorganize headers and split hardware part
The TPM subsystem does not have a full front-end/back-end separation.
The sole available backend, tpm_passthrough, depends on the data
structures of the sole available frontend, tpm_tis.

However, we can at least try to split the user interface (tpm.c) from the
implementation (hw/tpm).  The patches makes tpm.c not include tpm_int.h,
which is shared between tpm_tis.c and tpm_passthrough.c; instead it
moves more stuff to tpm_backend.h.

Peter Maydell 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.

Stefan Berger d1a0cf738d Support for TPM command line options
This patch adds support for TPM command line options.
The command line options supported here are

./qemu-... -tpmdev passthrough,path=<path to TPM device>,id=<id>
           -device tpm-tis,tpmdev=<id>,id=<other id>

and

./qemu-... -tpmdev help

where the latter works similar to -soundhw help and shows a list of
available TPM backends (for example 'passthrough').

Using the type parameter, the backend is chosen, i.e., 'passthrough' for the
passthrough driver. The interpretation of the other parameters along
with determining whether enough parameters were provided is pushed into
the backend driver, which needs to implement the interface function
'create' and return a TPMDriverOpts structure if the VM can be started or
'NULL' if not enough or bad parameters were provided.

Monitor support for 'info tpm' has been added. It for example prints the
following:

(qemu) info tpm
TPM devices:
 tpm0: model=tpm-tis
  \ tpm0: type=passthrough,path=/dev/tpm0,cancel-path=/sys/devices/pnp0/00:09/cancel

For now, make this clearer by moving the qapi-*.o definitions out

should not include anymore qapi-types.o and qapi-visit.o.

Paolo Bonzini 3bc2f570ec build: replace weak symbols with a static library
Weak symbols were a nice idea, but they turned out not to be a good one.
Toolchain support is just too sparse, in particular llvm-gcc is totally
broken.

This patch uses a surprisingly low-tech approach: a static library.
Symbols in a static library are always overridden by symbols in an
object file.  Furthermore, if you place each function in a separate
source file, object files for unused functions will not be taken in.
This means that each function can use all the dependencies that it needs
(especially QAPI stuff such as error_setg).

Thus, all stubs are placed in separate object files and put together in
a static library.  The library then is linked to all programs.

Paolo Bonzini d354c7eccf aio: add generic thread-pool facility
Add a generic thread-pool.  The code is roughly based on posix-aio-compat.c,
with some changes, especially the following:

- use QemuSemaphore instead of QemuCond;

- separate the state of the thread from the return code of the worker
function.  The return code is totally opaque for the thread pool;

- do not busy wait when doing cancellation.

A more generic threadpool (but still specific to I/O so that in the future
it can use special scheduling classes or PI mutexes) can have many uses:
it allows more flexibility in raw-posix.c and can more easily be extended
to Win32, and it will also be used to do an msync of the persistent bitmap.
