If there is a single colon for a given target and the target
is redefined in another place (e.g. in included file) then
make executes only new target and displays following warning:
Makefile:35: warning: overriding commands for target `clean'
tools/libfsimage/common/../../../tools/libfsimage/Rules.mk:25:
warning: ignoring old commands for target `clean'
To cope with that issue define all required targets as double-colon
rules. Additionally, remove some redundant stuff.

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.

Currently shared libraries are automatically installed into /usr/lib
or /usr/lib64, depending on the supplied --prefix value and
$(XEN_TARGET_ARCH). Some systems, like recent Debian and Ubuntu releases,
do not use /usr/lib64, but instead /usr/lib/x86_64-linux-gnu.
With this change, packagers can supply the desired location for shared
libraries on the ./configure command line. Packagers need to note that
the default behaviour on 64-bit Linux systems will be to install shared
libraries in /usr/lib, not /usr/lib64, unless a --libdir value is provided
to ./configure.
Additionally, the libfsimage plugins are now loaded explicitly from
$LIBDIR/fs, removing platform-based decision trees in code.

tools/libfsimage/Rules.mk relies on having certain variables set already; if
they're not set, the definitions dont' work right. The result was a bunch
of empty files and pygrub failing with an uninformative error message.
It's likely that this didn't cause anyone problems becasue changing the
Makefiles didn't cause a re-build; building from a fresh repo results in
completely empty filesystem plugin binaries.

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.

Create two new variables called APPEND_ and PREPEND_ to add compile
flags at the beginning or at the end of the search path.
Added a new semantic for user defined compile flags, here is the list
of possible options:
PREPEND_LIB: add libraries to the search path before xen
(before xen installation folders).
PREPEND_INCLUDES: add headers to the search path before xen
(before xen installation folders).
APPEND_LIB: add libraries to the search path at the end
(after all xen installation folders have been added).
APPEND_INCLUDES: add libraries to the search path at the end
(after all xen installation folders have been added).
EXTRA_INCLUDES and EXTRA_LIB can still be used, and they will have the
same effect as PREPEND_INCLUDES and PREPEND_LIB.

If you use -MMD -MF then the correct .o filename is written to the
.*.d file as the compiler driver arranges everything. This was done
in 19010:275abe1c5d24 for the hypervisor.
In this patch we do the same elsewhere in the xen-unstable tree,
particularly tools/. Specifically:
* Change tools/Rules.mk to add -MMD -MF ... to CFLAGS and set DEPS.
* Remove -Wp,-MD... from every other Makefile
* Remove setting of DEPS from every other Makefile
* Ensure that every Makefile says -include $(DEPS)
* Ensure that every Makefile's clean target removes $(DEPS)
Some Makefiles were already halfway there, but often for a different
variable name eg PROG_DEP. The variable name is now standardised in
Rules.mk as DEPS.
I have done a test build with this change, on Debian etch.

Preference seems to be to update library versions only when the ABI
changes. Only libxenctrl/libxenguest have their version number changed
to 3.2.0, as a reminder that they change on pretty much every major
release.
libfsimage/libxenstore/libblktap have not changed substantially
recently, hence the ABI has not changed, and version number stays the
same as in Xen 3.1 (and before).

* Arrange for the sonames of libxenstore, libxc, libfsimage and
libblktap to be set from a single place in Config.mk.
* Bumps the soname major version number to 3.2 in preparation for
3.2 rc1 after which we do not expect to have ABI changes.
I have not done anything about libaio and libflask. The former is
imported from elsewhere and if we're lucky will have sane versioning
upstream.
libflask has a very small interface and I'm hoping that the XSM
authors have been keeping some ABI discipline.
