Introduce an autoconf macro to check for the include path of certain
headers that can be different between OSes.
Use such macro to find the correct path for the endian.h header, and
modify the users of endian.h to use the output of such check.

There is no reason why libxenstore is not placed in the tools/libs
directory.
The common files between libxenstore and xenstored are kept in the
tools/xenstore directory to be easily accessible by xenstore-stubdom
which needs the xenstored files to be built.

libxenstore3.0 in Xen 4.8 had this function. We don't really want to
bump the ABI version (soname) just for this, since we don't think
there are actual callers anywhere. But tools complain about the
symbol going away.
So, provide a function xs_restrict which conforms to the original
semantics, although it always fails.

These definitions were not properly protected from unwanted operator
precedence interactions.
Existing use sites in-tree all use & or |, so this does not change any
actual behaviour in-tree.
The same seems likely to be true in external callers.

In preparation to support other than pure debug functionality via the
Xenstore XS_DEBUG wire command rename it to XS_CONTROL and make
XS_DEBUG an alias of it.
Add an alias xs_control_command for the associated xs_debug_command,
too.

XS_RESTRICT and the xenstore library function xs_restrict() have never
been usable in all configurations and there are no known users.
This functionality was thought to limit access rights of device models
to xenstore in order to avoid affecting other domains in case of a
security breech. Unfortunately XS_RESTRICT won't help as current
qemu is requiring access to dom0 only accessible xenstore paths to
work correctly. So this command is useless and should be removed.
In order to avoid problems in the future remove all support for
XS_RESTRICT from xenstore.

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.

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

Some of the changed files are imports from elsewhere, however
filtering them out is tricky, I think it is tolerable to have these

since it's only 1-2 lines and obvious what is going on.

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.
