The hex() function results in different output on 32bit systems. It adds
a L for long for some numbers. Thus we have a different header file.
This patch makes sure we have a consistent file generation on different

Nobody uses the function nfs4acl_test.
It took a while to figure out how to get this to build. The "uuid" line in the
idl file triggers pidl to generate the function table entry, which in turn then
triggers tables.pl to register this interface
./bin/default/source4/librpc/gen_ndr/tables.c. We could for example do the same
with xattr_parse_DOSATTRIB. Nobody uses this.

Since the glusterfs vfs module does not operate on a
locally mounted path, but on a "virtual" path starting
at the volume root, some assumptions of the code about
the vfs connect path fail. One example is the shadow_copy2
module which tries to detect the mount point from the
connectpath. In order to circumvent this problem, this
patch forces the "shadow:mountpoint" option to "/", which
skips the mount-point-detection code.
This patch will only have an effect if both the glusterfs
and the shadow_copy2 module are listed in vfs objects
in the right order, i.e. first shadow_copy2, and then
glusterfs.

replmd_build_la_val() is creating a new link attribute. In this case,
the RMD_ORIGINATING_USN and RMD_LOCAL_USN are always going to be the
same thing, so we don't need to pass them in as 2 separate parameters.
This isn't required for any bug fix, but is just a general code
tidy-up.

replmd_build_la_val() and replmd_set_la_val() are pretty much identical.
Keep the replmd_build_la_val() API (as it makes it clearer we're
creating a new linked attribute), but replace the code with a call to
replmd_set_la_val().

current value of dwVersion is less than 0xFFFFFFFF, then increment it

replmd_build_la_val() is used to populate a new link attribute value
from scratch. The version parameter is always passed in as the initial
value (zero), and deleted is always passed in as false.
For cases (like replication) where we want to set version/deleted to
something other than the defaults, we can use replmd_set_la_val()
instead.
This patch changes these 2 parameters to variables instead.

Link conflict handling is a corner-case. The logic in
replmd_process_linked_attribute() is already reasonably busy/complex.
Split out the handling of link conflicts into a separate function so
that it doesn't detract from the core replmd_process_linked_attribute()
logic too much.
This refactor should not alter functionality.
