463fa9c762 m4: checking if ssh_get_server_publickey() exists.
This commit adds some checks inside libssh m4 checking to verify if
ssh_get_server_publickey is available. This new function scope replaces
the old ssh_get_publickey() from libssh 0.7.5 and below. Assuming that
some distros are not showing the right version of libssh. This is a
simple way to check which function is available.

c0a8ea450d po: provide custom make rules for po file management
Historically we have relied on autopoint/gettextize to install a
standard po/Makefile.in.in. There is very limited scope for customizing
this and it also causes a bunch of extra stuff to be pulled into
configure.ac which potentially clashes with gnulib. Writing make rules
for po file management is no more difficult than any other rules libvirt
has, so stop using autopoint/gettextize.

1dac5fbbbb Remove the xend driver
xend was deprecated in Xen 4.2 and removed from the Xen sources
before the Xen 4.5 release. The last Xen release to contain xend
was Xen 4.4, which was retired upstream in March 2017.

Remove xend support from libvirt since it is unrealistic to use
modern libvirt with ancient Xen.

67966ad518 m4: enforce that all enum cases are listed in switch statements
As a general rule any time we switch() on something that is an enum, we
want to have a case for every enum constant. The -Wswitch warning will
report any switch where we've violated this rule, except if that switch
has a default case.

Unfortunately it is reasonable to want to list all enum constants *and*
also have a default case. To get a warning in that scenario requires
that we turn on -Wswitch-enum.

In a few cases where we explicitly don't want to list all enum cases, we
can discard the enum type checking by casting the value to a plain int.

9148293018 m4: disable gcc8 -Wcast-function-type warnings from -Wextra
The -Wextra flag bundle gained a new warning -Wcast-function-type.
This complains if you cast between two function prototypes where
the number of parameters or their data types are not compatible.
Unfortunately we need such "bad" function casts for our event
callbacks. It is possible to silence the warning by first casting
to the generic "void (*)(void)" function prototype, but that is
rather ugly to add throughout libvirt code.

a1f6030def build: passing the "-z defs" linker flag to prevent undefined symbols
Undefined symbols are a bad thing in general because they can get
resolved in unexpected ways at runtime if multiple sources provide the
same symbol name. For example both glibc and libtirpc may provide XDR
symbols and we want to ensure that we resolve to libtirpc if that's what
we originally built against.

The toolchain maintainers thus strongly recommend that all applications
use the '-z defs' linker flag to prevent undefined symbols. This is
shortly becoming part of the default linker flags for RPMs. As an added
benefit this aligns Linux builds with Windows builds, where the linker
has never permitted undefined symbols.

d8e8b63d30 libxl: Add a test suite for libxl_domain_config generator
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.

bd4255680d m4/virt-arg: Move LIBVIRT_ARG_* macros to their own file

aac34eca90 m4/virt-gnutls: properly backup CFLAGS and LIBS for AC_CHECK_* macros

However we also need to backup and modify CFLAGS and do if for
AC_CHECK_HEADERS as well.
