8e9b0d24fb ui: convert VNC websockets to use crypto APIs
Remove the direct use of gnutls for hash processing in the
websockets code, in favour of using the crypto APIs. This
allows the websockets code to be built unconditionally
removing countless conditional checks from the VNC code.

488981a4af block: convert quorum blockdrv to use crypto APIs
Get rid of direct use of gnutls APIs in quorum blockdrv in
favour of using the crypto APIs. This avoids the need to
do conditional compilation of the quorum driver. It can
simply report an error at file open file instead if the
required hash algorithm isn't supported by QEMU.

nettle, then we should use nettle as a cipher backend in

c54e1eb492 qga: added GuestPCIAddress information
PCIAddress inforfation is obtained via SetupApi, which provides the
information about address, bus, etc. We look throught entire device tree
in the system and try to find device object for given volume. For this PDO
SetupDiGetDeviceRegistryProperty is called, which reads PCI configuration
for a given devicei if it is possible.

This is the most convinient way for a userspace service. The lookup is
performed for every volume available. However, this information is
not mandatory for vss-provider.

In order to use SetupApi we need to notify linker about it. We do not need
to install additional libs, so we do not make separate configuration
option to use libsetupapi.su

SetupApi gives as the same information as kernel driver
with IRP_MN_QUERY_INTERFACE.

This header file provides w32 ioctl definitions for working with disk
devices. Older versions of mingw do not expose this in a useable way,
so add a configure check and report it via CONFIG_QGA_NTDDSCSI.

Subsequent patches will use this macro to stub out functionality that
relies on this in cases where it's not available.

ddbb0d0966 crypto: introduce new module for computing hash digests
Introduce a new crypto/ directory that will (eventually) contain
all the cryptographic related code. This initially defines a
wrapper for initializing gnutls and for computing hashes with
gnutls. The former ensures that gnutls is guaranteed to be
initialized exactly once in QEMU regardless of CLI args. The
block quorum code currently fails to initialize gnutls so it
only works by luck, if VNC server TLS is not requested. The
hash APIs avoids the need to litter the rest of the code with
preprocessor checks and simplifies callers by allocating the
correct amount of memory for the requested hash.

31ce0adb79 configure: Check for libfdt version 1.4.0
Some recent patches require a function from libfdt version 1.4.0,
so we should check for this version during the configure step
already. Unfortunately, there does not seem to be a proper #define

we check for the availability of the required function
fdt_get_property_by_offset() instead instead.

fd0e60530f configure: Add workaround for ccache and clang
Test if ccache is interfering with semantic analysis of macros,
disable its habit of trying to compile already pre-processed
versions of code if so. ccache attempts to save time by compiling
pre-processed versions of code, but this disturbs clang's static
analysis enough to produce false positives.

ccache allows us to disable this feature, opting instead to
compile the original version instead of its preprocessed version.
This makes ccache much slower for cache misses, but at least it
becomes usable with QEMU/clang.

This workaround only activates for users using ccache AND clang,
and only if their configuration is observed to be producing warnings.
You may need to clear your ccache for builds started without -Werror,
as those may continue to produce warnings from the cache.

Thanks to Peter Eisentraut for his writeup on the issue:

bbbf2e04e5 configure: silence glib unknown attribute __alloc_size__
The glib headers use GCC attributes.  Unfortunately the __GNUC__ and
__GNUC_MINOR__ version macros are also defined by clang, but clang
doesn't support the same attributes as GCC.

clang 3.5.0 does not support the __alloc_size__ attribute:

  c047507a9a

The following warning is produced:

  gstrfuncs.h:257:44: warning: unknown attribute '__alloc_size__' ignored [-Wunknown-attributes]
        G_GNUC_MALLOC G_GNUC_ALLOC_SIZE(2);

                #define G_GNUC_ALLOC_SIZE(x) __attribute__((__alloc_size__(x)))

This patch checks whether glib headers cause warnings and disables
-Wunknown-attributes if it is able to.

2847b46958 configure: Add support for tcmalloc
This adds "--enable-tcmalloc" and "--disable-tcmalloc" to allow linking
to libtcmalloc from gperftools.

tcmalloc is a malloc implementation that works well with threads and is
fast, so it is good for performance.

It is disabled by default, because the MALLOC_PERTURB_ flag we use in
tests doesn't work with tcmalloc. However we can enable tcmalloc
specific heap checker and profilers later.

An IOPS gain can be observed with virtio-blk-dataplane, other parts of
QEMU will directly benefit from it as well:

ae6e8ef11e Revert seccomp tests that allow it to be used on non-x86 architectures
Unfortunately it turns out that libseccomp 2.2 still does not work
correctly on non-x86 architectures; return to the previous configure
setup of insisting on libseccomp 2.1 or better and i386/x86_64 and
disabling seccomp support in all other situations.

This reverts the two commits:
 * "seccomp: libseccomp version varying according to arch"
   (commit 896848f0d3)
 * "seccomp: update libseccomp version and remove arch restriction"
   (commit 8e27fc2004)

6a460ed18a configure: disable Archipelago by default and warn about libxseg GPLv3 license
libxseg has changed license to GPLv3.  QEMU includes GPL "v2 only" code
which is not compatible with GPLv3.  This means the resulting binaries
may not be redistributable!

Disable Archipelago (libxseg) by default to prevent accidental license
violations.  Also warn if linking against libxseg is enabled to remind
the user.

Note that this commit does not constitute any advice about software
licensing.  If you have doubts you should consult a lawyer.

896848f0d3 seccomp: libseccomp version varying according to arch
Libseccomp dependency was mandating version 2.2.0 on all architectures
and this was causing configure and virt-test to break on non-updates
distros. This patch works-around it and give a more flexible way to
check the version, giving more time for other distros to update
libseccomp version.

6b383c08c4 block/dmg: support bzip2 block entry types
This patch adds support for bzip2-compressed block entries as introduced
with OS X 10.4 (source: https://en.wikipedia.org/wiki/Apple_Disk_Image).

It was tested against a 5.2G "OS X Yosemite" installation image which
stores the BLXX block in the XML property list (instead of resource
forks) and has over 5k chunks.

New configure entries are added (--enable-bzip2 / --disable-bzip2) to
control inclusion of bzip2 functionality (which requires linking against
libbz2). The help message suggests that this option is needed for DMG
files, but the tests are generic enough that other parts of QEMU can use
bzip2 if needed.

The identifiers are based on http://newosxbook.com/DMG.html.

The decompression routines are based on the zlib case, but as there is
no way to reset the decompression state (unlike zlib), memory is
allocated and deallocated for every decompression. This should not be
problematic as the decompression takes most of the time and as blocks
are typically about/over 1 MiB in size, only one allocation is done
every 2000 sectors.

3996e85c18 Xen: Use the ioreq-server API when available
The ioreq-server API added to Xen 4.5 offers better security than
the existing Xen/QEMU interface because the shared pages that are
used to pass emulation request/results back and forth are removed
from the guest's memory space before any requests are serviced.
This prevents the guest from mapping these pages (they are in a
well known location) and attempting to attack QEMU by synthesizing
its own request structures. Hence, this patch modifies configure
to detect whether the API is available, and adds the necessary
code to use the API if it is.
