fruit_pread doesn't check the offset and length parameters and instead
always writes 60 bytes, the size of the AFP_AfpInfo blob, to the the
passed buffer. If the passed in buffer is smaller, we overwrite
something somewhere.

Implement Apple's special copy_chunk ioctl that requests a copy of the
whole file along with all attached metadata.
These copy_chunk requests have a chunk count of 0 that we translate to a
copy_chunk_send VFS call overloading the parameters src_off = dest_off =
num = 0.

vfs_fruit adds a wildcard path "._*" to the vetolist in order to prevent
client access to ._ AppleDouble files created internally by vfs_fruit
for storing the Mac resource fork stream.
Unfortunately there are legitimite use cases where an OS X client may
want to use such filenames, extracting ZIP archives (where the archive
contains ._ files) being one of them.
A possible simple solution to this problem would be to not veto ._ files
in the first place, even though that exposes internally created ._ files
which the client shouldn't be able to access.

we need to map 0x01-0x1F to 0xF001-0xF01F as 0x01-0x1F are win32 illegal
characters.

Even if the MS KB article writes "invalid ntfs characters" they are actually
not illegal in ntfs, just in the win32 API.

Trying for fixup a broken AppleDouble file with a resourcefork entry
offset + length > filesystem resulted in a crashing memmove() in
ad_convert().
Add a specific safety check that stats the ._ file and limits the
resource fork length to the filesize.
While we're at it, now that we know the filesize in ad_unpack(), add
additional checks that verify this.

The Linux fallocate syscall offers a mode parameter which can take the
following flags:
FALLOC_FL_KEEP_SIZE
FALLOC_FL_PUNCH_HOLE (since 2.6.38)
FALLOC_FL_COLLAPSE_RANGE (since 3.15)
FALLOC_FL_ZERO_RANGE (since 3.14)
The flags are not exclusive, e.g. FALLOC_FL_PUNCH_HOLE must be specified
alongside FALLOC_FL_KEEP_SIZE.
Samba currently takes a vfs_fallocate_mode enum parameter for the VFS
fallocate hook, taking either an EXTEND_SIZE or KEEP_SIZE value. This
commit changes the fallocate hook such that it accepts a uint32_t flags
parameter, in preparation for PUNCH_HOLE and ZERO_RANGE support.

This module provides enhanced compatibility with Apple SMB clients and
interoperability with a Netatalk 3 AFP fileserver.
The module intercepts the OS X special streams "AFP_AfpInfo" and
"AFP_Resource" and handles them in a special way. All other named
streams are deferred to vfs_streams_xattr.
The OS X client maps all NTFS illegal characters to the Unicode
private range. This module optionally stores the charcters using their
native ASCII encoding.
Open modes are optionally checked against Netatalk AFP share modes.
The "AFP_AfpInfo" named stream is a binary blob containing OS X
extended metadata for files and directories. This module optionally
reads and stores this metadata in a way compatible with Netatalk 3
which stores the metadata in an EA "org.netatalk.metadata". Cf
source3/include/MacExtensions.h for a description of the binary blobs
content.
The "AFP_Resource" named stream may be arbitrarily large, thus it
can't be stored in an EA on most filesystem. ZFS on Solaris is an
exception to the rule, because it there EAs can be of any size and EAs
are first-class filesystem objects that can be used with normal file
syscalls like open(), read(), write(), fcntl() asf. This module stores
the AFP_Resource stream in an AppleDouble file, prepending "._" to the
filename. On Solaris and ZFS the stream is optionally stored in an EA
"org.netatalk.ResourceFork".
