Event-driven programs want to wait until the xs_fileno triggers for
reading, and then repeatedly call xs_check_watch.
Also xs_read_watch exposes a useless "num" out parameter, which should
always (if things aren't going hideously wrong) be at least 2 and
which the caller shouldn't be interested in. So xs_check_watch
doesn't have one of those.

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.

Otherwise make can search the path relative to certain standard paths
such as /usr/include (e.g., the line '-include $(XEN_ROOT)/.config' in
Config.mk suffers from this).

Linker command lines are order-sensitive.
Move linker options -Lfoo -lfoo from LDFLAGS to LDLIBS and place this new
variable after the objects to link. This resolves build errors in xenpagin
and blktap with recent toolchains.

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.

This is done separately from moving the other utilities into the

This removes threading from libxenstore.a (but not libxenstore.so)
since pthreads is incompatible with static linking and none of the
command line clients require threads anyway.
It is now possible to build these utilities statically with a uclibc
toolchain which is useful for small userspace utility domains.

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.

This utility permits developers and administrators to
manually change the permissions on arbitrary locations in XenStore
from the command line. This is often helpful if you're trying to debug an
application that relies on XenStore and is encountering difficulties
with permissions.

long ago accidents of implementation in historical Unixes. And there
are various tools which "expect" it (... and this is why they get

Added two flags, -R and -L, to disable the recovery code and the remove of
/local at start-up. This makes it much easier to analyse corrupted tdb files.
Added some missing talloc_free calls in the previous integrity checking code.
