copy_chunk copies n bytes from a source file at a specific offset to a
destination file at a given offset. This interface will be used in
handling smb2 FSCTL_SRV_COPYCHUNK ioctl requests.
Use a pread/pwrite loop in vfs_default, so that requests referring to
the same src and dest file are possible.
Provide send and receive hooks for copy chunk VFS interface, allowing
asynchronous behaviour.
Check whether the request source offset + length exceeds the current
size. Return STATUS_INVALID_VIEW_SIZE under such a condition, matching
Windows server behaviour.

The definitions for default client timeout values have been moved to client.h. When initializing a client struct we use this value instead of the old hardcoded value. The timeout value remains 20 seconds.

POSIX ACLs backend.
Change can_delete_directory() to can_delete_directory_fsp(), as
we only ever call this from an open directory file handle.
This allows us to use OpenDir_fsp() instead of OpenDir().
OpenDir() re-checks the ACL on the directory, which may
refuse DIR_LIST permissions. OpenDir_fsp() does not. As
this is a file-server internal check to see if the directory
actually contains any files before setting delete on close,
we can ignore the ACL here (Windows does).

NT4 is long dead, and we should not change which ACL we return based
on what we think the client is. The reason we should not do this, is
that if we are using vfs_acl_xattr then the hash will break if we do.
Additionally, it would require that the python VFS interface set the
global remote_arch to fake up being a modern client.
This instead seems cleaner and removes untested code (the tests are
updated to then handle the results of the modern codepath).
The supporting 'acl compatability' parameter is also removed.

This interface actually needs to match the get_nt_acl interface in
that the system ACL implmenetation may not be posix ACLs, and the blob
is not meant to be enforced to be of a particular system ACL
structure.

This makes it clear which context the returned SD is allocated on, as
a number of callers do not want it on talloc_tos().
As the ACL transformation allocates and then no longer needs a great
deal of memory, a talloc_stackframe() call is used to contain the
memory that is not returned further up the stack.
Andrew Bartlett

This changes from allocation on NULL to allocation on the supplied
memory context.
Currently that supplied context is talloc_tos() at the the final consumer of
the ACL.

Avoid overriding default ccache for ads operations.
Nowadays various samba components may need to use GSSAPI and a default cred
cache to perform their tasks.
This code was completely overriding the whole process default ccache name, thus
altering the current credentials and sometimes hijacking them (or getting
preemptively hijaked).
By using gss_krb5_import_cred we can instead use a private ccache (necessary
sometimes to use a different set of credentials fromt he default
cifs/fqdn@realm one, for example when contacting foreign DCs using trust
credentials) that does not affect the rest of the process.
For the kerberos versions which don't have gss_krb5_import_cred
we fallback to temp override of KRB5CCNAME and gss_acquire_cred.

This will allow us to hash this, rather than the NT ACL it maps to.
This will in turn allow us to know if the NT ACL is valid even if we
have to change the mapping code.

This is in order to be able to turn durable handles off and on on a per share
basis.
Note: This is only used in combination with:
kernel share modes = no
kernel oplocks = no
posix locking = no
Which means CIFS/SMB2 only access.

PDB modules store domain sid and guid in secrets.tdb to cooperate
with other parts of smbd. If PDB module is built outside Samba
source code it has to be linked against internal libsecrets.
Wrap required secrets_* calls to avoid direct linking. libpdb
is linked against libsecrets by itself and this is enough.

Not used right now but I need this in the VFS to implement open for
backup/restore later and don't want to break the ABI once 4.0.0

secrets_tdb_sync
secrets_tdb_sync will be a new ldb module designed to sync secrets.ldb
entries with the secrets.tdb file.
While not ideal to keep two copies of this data, this routine will
assist in allowing the samba-tool domain join code to operate
correctly in most cases where winbindd and smbd are used.

We no longer do struct smb_acl_t manipuations via the VFS layer,
which is now reduced to handling the get/set functions.
The only backend that implemented these functions (aside from audit)
was the vfs_default module calling the sys_acl code. The various ACL
implementation modules either worked on the fully initilaised
smb_acl_t object or on NT ACLs.
This not only makes the operation of the posix ACL code more efficient
(as allocation and free is not put via the VFS), it makes it easier to
test and removes the fantasy that a module could safely redefine this
structure or the behaviour here.
The smb_acls.idl now defines the structure, and it is now allocated
with talloc.
These operations were originally added to the VFS in commit
3bb219161a270f12c27c3bc7e1220829c6e9f284.

This will allow us to marshall this into and from an NDR blob on disk, which will
allow us to fake up ACL support during make test, and to test the NT ACL emulation
using python bindings via the VFS.

The acl element is changed to be a talloc child, and is no longer one element
longer than requested by virtue of the acl[1] base pointer.
This also avoids one of the few remaining cases of over-allocation of a structure.
