In order to be able to support reading the list of a node's children in
multiple chunks (needed for list sizes > 4096 bytes) without having to
allocate a temporary buffer we need some kind of generation counter for
each node. This will help to recognize a node has changed between
reading two chunks.
As removing a node and reintroducing it must result in different
generation counts each generation value has to be globally unique. This
can be ensured only by using a global 64 bit counter.
For handling of transactions there is already such a counter available,
it just has to be expanded to 64 bits and must be stored in each
modified node.

The layout of the tdb record of xenstored is defined at multiple
places: read_node(), write_node() and in xs_tdb_dump.c
Use a common structure instead.

xs_perm_to_string takes a size_t which isn't defined by anything
pulled in directly by this header.
Given the other headers xenstore_lib.h pulls in this looks to be an
oversight rather than a deliberate policy.

The only remaining mentions of these addresses are in COPYING files which I
haven't touched.
Some of the changed files are imports from elsewhere, however
filtering them out is tricky, I think it is tolerable to have these
files be modified here and then perhaps reverted on the next sync,
since it's only 1-2 lines and obvious what is going on.

Added to the xs_open() comments in xenstore.h. The text has been
taken almost verbatim from a xen-devel email by Ian Campbell,
and confirmed as accurate by Ian Jackson.

Also moves xc_dom.h to include as it is used often by other xen tools.
Use the new include subdirectories to build Xen tools, qemu-xen and
stubdoms.
Add the old libxc include path to the programs that need it to build,
on a case by case basis and commeting that they shouldn't require
internal libxc headers to build.
[ And: update QEMU_TRADITIONAL_REVISION to corresponding qemu patch
