docs: filesystems: convert hfsplus.txt to ReST
Just trivial changes:
- Add a SPDX header;
- Add it to filesystems/index.rst.
While here, adjust document title, just to make it use the same
style of the other docs.

+======================================
+Macintosh HFSPlus Filesystem for Linux
+======================================
+
+HFSPlus is a filesystem first introduced in MacOS 8.1.
+HFSPlus has several extensions to HFS, including 32-bit allocation
+blocks, 255-character unicode filenames, and file sizes of 2^63 bytes.
+
+
+Mount options
+=============
+
+When mounting an HFSPlus filesystem, the following options are accepted:
+
+ creator=cccc, type=cccc
+ Specifies the creator/type values as shown by the MacOS finder
+ used for creating new files. Default values: '????'.
+
+ uid=n, gid=n
+ Specifies the user/group that owns all files on the filesystem
+ that have uninitialized permissions structures.
+ Default: user/group id of the mounting process.
+
+ umask=n
+ Specifies the umask (in octal) used for files and directories
+ that have uninitialized permissions structures.
+ Default: umask of the mounting process.
+
+ session=n
+ Select the CDROM session to mount as HFSPlus filesystem. Defaults to
+ leaving that decision to the CDROM driver. This option will fail
+ with anything but a CDROM as underlying devices.
+
+ part=n
+ Select partition number n from the devices. This option only makes
+ sense for CDROMs because they can't be partitioned under Linux.
+ For disk devices the generic partition parsing code does this
+ for us. Defaults to not parsing the partition table at all.
+
+ decompose
+ Decompose file name characters.
+
+ nodecompose
+ Do not decompose file name characters.
+
+ force
+ Used to force write access to volumes that are marked as journalled
+ or locked. Use at your own risk.
+
+ nls=cccc
+ Encoding to use when presenting file names.
