This is the version from Debian Wheezy which is what both Ian Jackson and
myself run on our workstations. As committers it is useful to minimise
regeneration noise.
This is purely a run of autogen.sh. I have not tried to build the result.

If this option is given don't bother building qemu-xen ourselves. Likely to be
handy for distros who have an existing qemu package which they want to reuse.

Now that we have upstream qemu people may want to avoid building this extra
code.
There is a little bit of trickery in stubdom/configure.ac to ensure that the
ioemu stubdom is only built if qemu-traditional is enabled.
libxl will return an error if a caller tries to build a domain using
qemu-xen-traditional when this support was disabled at build time. Since
qemu-xen-traditional has been historically tightly bound to the Xen releases I
don't see any value in supporting "3rd party" provision of
qemu-xen-traditional.
We also do not want/need this on ARM therefore default is on for x86 and off
otherwise.

We have defaulted to using the system libaio for a while now and I din't think
there are any relevant distros which don't have it that running Xen 4.4 would
be reasonable on.
Also it has caused confusion because it is not ever wanted on ARM, but the
build system doesn't express that (could be fixed, but deleting is the right
thing to do anyway).

arm64 only has the eventfd2 system call and using the libc wrapper when
available hides this from us. eventfd() has been in libc since glibc 2.8.
This code is already Linux specific.

getconf is not cross-compile friendly since it reports the features of the host
and not the target. There doesn't appear to be a $triplet-getconf.
AC_SYS_LARGEFILE arranges for #defines to appear in config.h however Xen's
build system expects these to be part of C{PP}FLAGS. Since I'm not confident
that everything in Xen includes config.h I instead arrange for the result of
running AC_SYS_LARGERFILE to end up in CFLAGS.

CentOS 5.x forked e2fs ext4 support into a different package called
e4fs, and so headers and library names changed from ext2fs to ext4fs.
Check if ext4fs/ext2fs.h and -lext4fs work, and use that instead of
ext2fs to build libfsimage. This patch assumes that if the ext4fs
library is present it should always be used instead of ext2fs.
This patch includes a rework of the ext2fs check, a new ext4fs check
and a minor modification in libfsimage to use the correct library.

Which was introduced in 7b0dc7f3ddfe. This is because the NUMA
placement heuristic does not need FP arith anymore.
As usual when changing configure.ac, remember to rerun autoconf
after applying this change.

As well as explicitly add -lm to libxl's Makefile.
This is because next patch uses floating point arithmetic, and
it is better to state it clearly that we need libmath (just in
case we find a libc that wants that to be explicitly enforced).
Notice that autoconf should be rerun after applying this change.

We may need to #include <libutil.h>, and/or link with -lutil, to use
openpty, login_tty, and the like. Provide INCLUDE_LIBUTIL_H
(preprocessor constant, not always defined) and PTYFUNCS_LIBS
(makefile variable).
We link libxl against PTYFUNCS_LIBS (which comes from autoconf) rather
than UTIL_LIBS, and #include <libutil.h> where appropriate.

Changes since v7:
* Actually include the call to AX_CHECK_PTYFUNCS in this patch,
not the previous one, and regenerate configure accordingly.
Changes since v6:
* Put failure macro call in correct place so it might actually happen.
* Try both with -lutil and without.
* Patch now contains update for config.h.in.

Remove a lot of unnecessary tests. Specifically, we no longer test
for standard POSIX facilities which we expect to be provided
everywhere and which we don't in any case have any alternative for.
Switch to generating config.h.in with autoheader.

Check for a curses compatible library (curses or ncurses basically).
One of those is needed to compile Xen tools (gtraceview and xentop).
Modify Makefiles/sources to use configure output (fetch CURSES_LIBS
from tools/Tools.mk and header to include from tools/config.h)

Added autotools magic to replace custom check scripts. The previous
checks have been ported to autoconf, and some additional ones have
been added (plus the suggestions from running autoscan). Two files are
created as a result from executing configure script, config/Tools.mk
and config.h.
conf/Tools.mk is included by tools/Rules.mk, and contains most of the
options previously defined in .config, that can now be set passing
parameters or defining environment variables when executing configure
script.
config.h is only used by libxl/xl to detect yajl_version.h.
[ tools/config.sub and config.guess copied from
autotools-dev 20100122.1 from Debian squeeze i386,
which is GPLv2.
tools/configure generated using the included ./autogen.sh
which ran autoconf 2.67-2 from Debian squeeze i386. autoconf
is GPLv3+ but has a special exception for the autoconf output;
this exception applies to us and exempts us from complying
with GPLv3+ for configure, which is good as Xen is GPL2 only.
