Moved, renamed, and deleted files

The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

- * PURPOSE
- *  Super block routines for the OSTA-UDF(tm) filesystem.

- * DESCRIPTION
- *  OSTA-UDF(tm) = Optical Storage Technology Association
- *  Universal Disk Format.
- *
- *  This code is based on version 2.00 of the UDF specification,
- *  and revision 3 of the ECMA 167 standard [equivalent to ISO 13346].

- * HISTORY
- *
- *  09/24/98 dgb  changed to allow compiling outside of kernel, and
- *                added some debugging.
- *  10/01/98 dgb  updated to allow (some) possibility of compiling w/2.0.34
- *  10/16/98      attempting some multi-session support
- *  10/17/98      added freespace count for "df"
- *  11/11/98 gr   added novrs option
- *  11/26/98 dgb  added fileset,anchor mount options
- *  12/06/98 blf  really hosed things royally. vat/sparing support. sequenced
- *                vol descs. rewrote option handling based on isofs
- *  12/20/98      find the free space bitmap (if it exists)

- * udf_parse_options
- *
- * PURPOSE
- *	Parse mount options.
- *
- * DESCRIPTION
- *	The following mount options are supported:
- *
- *	gid=		Set the default group.
- *	umask=		Set the default umask.
- *	mode=		Set the default file permissions.
- *	dmode=		Set the default directory permissions.
- *	uid=		Set the default user.
- *	bs=		Set the block size.
- *	unhide		Show otherwise hidden files.
- *	undelete	Show deleted files in lists.
- *	adinicb		Embed data in the inode (default)
- *	noadinicb	Don't embed data in the inode
- *	shortad		Use short ad's
- *	longad		Use long ad's (default)
- *	nostrict	Unset strict conformance
- *	iocharset=	Set the NLS character set
- *
- *	The remaining are for debugging and disaster recovery:
- *
- *	novrs		Skip volume sequence recognition
- *
- *	The following expect a offset from 0.
- *
- *	session=	Set the CDROM session (default= last session)
- *	anchor=		Override standard anchor location. (default= 256)
- *	volume=		Override the VolumeDesc location. (unused)
- *	partition=	Override the PartitionDesc location. (unused)
- *	lastblock=	Set the last block of the filesystem/
- *
- *	The following expect a offset from the partition root.
- *
- *	fileset=	Override the fileset block location. (unused)
- *	rootdir=	Override the root directory location. (unused)
- *		WARNING: overriding the rootdir to a non-directory may
- *		yield highly unpredictable results.
- *
- * PRE-CONDITIONS
- *	options		Pointer to mount options string.
- *	uopts		Pointer to mount options variable.
- *
- * POST-CONDITIONS
- *	<return>	1	Mount options parsed okay.
- *	<return>	0	Error parsing mount options.
- *
- * HISTORY
- *	July 1, 1997 - Andrew E. Mileski
- *	Written, tested, and released.
