306783d6f5 lib: modules: Change XXX_init interface from XXX_init(void) to XXX_init(TALLOC_CTX *)
Not currently used - no logic changes inside.

This will make it possible to pass down a long-lived talloc
context from the loading function for modules to use instead
of having them internally all use talloc_autofree_context()
which is a hidden global.

Updated all known module interface numbers, and added a
WHATSNEW.

41c4666a72 s3/vfs: remove unused SMB_VFS_DISK_FREE() small_query parameter
The small_query parameter for SMB_VFS_DISK_FREE() was, prior to the
previous commit, used to obtain 16-bit wide free-space information for
the deprecated dskattr SMB_COM_QUERY_INFORMATION_DISK command.

With the dskattr handler now performing the 16-bit collapse directly,
the small_query parameter can be removed from the entire code path.

32e9d7fa22 vfs_snapper: encode and decode Snapper DBus strings
Snapper uses a special character encoding for strings used in DBus
requests and responses. This change ensures that Samba packs and unpacks
strings in the corresponding format, using the previously added
encode/decode helper functions.

3d48fc9673 vfs_snapper: add DBus string encoding and decoding helpers
Snapper uses the following mechanism for encoding and decoding strings

Characters above 127 (0x7F - ASCII DEL) must be encoded hexadecimal as
"\x??". As a consequence "\" must be encoded as "\\".

This change adds string encoding and decoding helpers to vfs_snapper.

377a1c860e vfs: add previous file version support for vfs_snapper
Windows attempts to access previous file versions by first issuing an
FSCTL_SRV_ENUMERATE_SNAPSHOTS request, and then using the corresponding
snapshot timestamps in subsequent path based requests.

This change sees vfs_snapper provide snapshot enumeration data via the
get_shadow_copy_data VFS hook. Path based operations are also
intercepted, with @GMT-$time components converted to snapper .snapshot/#
paths.
