After b4f7793ce2, qemuxml2xmltest has apparently become big enough
to trigger a compilation error when using --enable-test-coverage on
aarch64:
CC qemuxml2xmltest.o
qemuxml2xmltest.c: In function 'mymain':
qemuxml2xmltest.c:1216:1: error: const/copy propagation disabled: 4361 basic blocks and 99285 registers [-Werror=disabled-optimization]

qemuxml2xmltest.c:1216:1: error: const/copy propagation disabled: 4361 basic blocks and 99285 registers [-Werror=disabled-optimization]
However, as the GCC documentation states, this warning is not really
caused by issues in our code, so it makes sense to disable it.

3 out of 4 uses of gl_WARN_ADD() were incorrectly adding "" around
the argument, which in turn resulted in the argument being used
unquoted (configure had gl_positive=""-fstack-protector-all"",
rather than the intended gl_positive="-fstack-protector-all").

When building libvirt with clang we get bogus warnings about
'double' being promoted to 'long double' when calling isnan().

Detect this broken isnan() / compiler combination and disable
the -Wdouble-promotion flag.

The libxl library allows a libxl_domain_config object to be serialized
from/to a JSON string. Use this to allow testing of the XML to
libxl_domain_config conversion process. Test XML is converted to
libxl_domain_config, which is then serialized to json. A json template
corresponding to the test XML is converted to a libxl_domain_config
object using libxl_domain_config_from_json(), and then serialized
back to json using libxl_domain_config_to_json(). The two json
docs are then compared.
Using libxl to convert the json template to a libxl_domain_config
object and then back to json provides a simple way to account for
any changes or additions to the json representation across Xen
releases.

The HTML pages are currently validated against an XHTML 1.0 DTD.
This makes it impossible to take advantage of features that are
introduced in HTML 5, because they'll fail validation.
There is intentionally no DTD defined for HTML 5, so there's no
alternative to XHTML 1.0 DTD that we could switch to. The only
options are to stick with XHTML 1.0 forever, or drop the DTD
validation, and we pick the latter.

GCC 7.1 introduces a new -Wformat-truncation warning
flag that reports if it thinks the maximum possible
size of the formatted output will exceed the provided
fixed buffer. This is enabled automatically by the
-Wformat warning flag. There are quite a few places
hit by this in libvirt which need rewriting. This is
non-trivial work in some places, so temporarily
disable the new warning until those fixes can be
implemented.

defined that's needed by the readline headers to use proper rl_message

This commit fixes an acl missing variable. The virt-acl.m4 inside the
macro directory does not contain the variable 'with_acl'. So, it is
being set as an empty string "with_acl=''". This is causing a missing
option during the configuration, even if you have acl libs installed.

If building libvirt against Ubuntu precise, the librbd.h is lacking
many functions that libvirt expects. We have no version check, so
we were enabling RBD even though it cannot compile. This configure
check uses existance of 'rbd_get_features' as an identifier for the
min required version.

Introduce STRICT_FRAME_LIMIT_CFLAGS that will be used for
production code and RELAXED_FRAME_LIMIT_CFLAGS for tests.
Raising the limit for tests allows building them with clang
with optimizations disabled.
The 'fs' backend m4 code was copied, but one of the condition were not
changed which resulted into:
configure: Gluster: yes
configure: ZFS: yes
configure: Virtuozzo storage: check
Make the code turn on the virtuozzo driver automatically if the tools
are found.
Added general definitions for vstorage pool backend including
the build options to add --with-storage-vstorage checking.
In order to use vstorage as a backend for a storage pool
vstorage tools (vstorage and vstorage-mount) need to be installed.

LIBVIRT_ARG_WITH_ALT is more generic than LIBVIRT_ARG_WITH, which
is tailored at switching features on and off.
Rename the macros according to their intended purpose, and add
some documentation to help developers pick between the two.

However we also need to backup and modify CFLAGS and do if for

Sigh, autoconf has AC_CHECK_FUNC and AC_CHECK_FUNCS and both check
whether some function exists or not. However in addition to the obvious
difference that the later is able to check multiple functions it also
defines HAVE_FUNCTION_NAME for each function.
Commit 680d2f49da moved the code to separate file, but also blindly
changed the macro to AC_CHECK_FUNC without confronting the
documentation.
