read_hex_bytes() is going to be used in lib/util/rfc1738.c.
parse_guid_string() is shifted for two reasons: Firstly, it is called
very often in some operations, sometimes constituting a few percent of
the CPU load, and it makes several calls to read_hex_bytes(). We want
the compiler to be able to inline those calls if it thinks that is
wise. Secondly, there are other places that could do with fast GUID
parsing.

Encrypt the samba secret attributes on disk. This is intended to
mitigate the inadvertent disclosure of the sam.ldb file, and to mitigate
memory read attacks.
Currently the key file is stored in the same directory as sam.ldb but
this could be changed at a later date to use an HSM or similar mechanism
to protect the key.
Data is encrypted with AES 128 GCM. The encryption uses gnutls where
available and if it supports AES 128 GCM AEAD modes, otherwise nettle is
used.

The "system" xattr namespace is reserved for the kernel. Any attempt to
use xattrs in that namesspace will fail with EOPNOTSUPP, regardless of
priveleges. In autobuild we're using the xattr_tdb VFS module, so it
works there.
Using the "security" namespace instead makes this module generally
usable with Linux filesystem xattrs as storage backend.
Additionally prefix the xattr name with "_ndr". This is in preperation
of later commits that add a ACL blob marshalling format based on XDR. To
avoid xattr name collision, both format will use distinct xattr names by
default.

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.

- Update IDL comments to include Microsoft reference doc
- Add support for sending v10 GetNCChanges request (needed for the
GET_TGT flag, which is in the new 'more_flags' field)
- Update to also set the GET_TGT flag in the same place we were setting
GET_ANC (I split this logic out into a separate function).
- The state struct now needs to hold a 'more_flags' field as well (this
flag is different to the GET_ANC replica flag)
Note that using the GET_TGT when replicating from a Windows DC could be
highly inefficient. Because Samba keeps the GET_TGT flag set throughout
the replication cycle, it will basically receive a repeated object from
Windows for every single linked attribute that it receives.
I believe Windows behaviour only expects the client to set the GET_TGT
flag when it actually needs to (i.e. when it receives a target object it
doesn't know about), rather than throughout the replication cycle.
However, this approach won't work with Samba-to-Samba replication,
because when the server receives the GET_TGT flag it restarts the
replication cycle from scratch. So if we only set the GET_TGT flag when
the client encountered an unknown target then Samba-to-Samba could
potentially get into an endless replication loop.
