 * @name:	attribute name to find (optional, i.e. NULL means don't care)
 * @name_len:	attribute name length (only needed if @name present)
 * @ic:		IGNORE_CASE or CASE_SENSITIVE (ignored if @name not present)
 * @val:	attribute value to find (optional, resident attributes only)
 * @val_len:	attribute value length
 * @ctx:	search context with mft record and attribute to search from
 *
 * You shouldn't need to call this function directly. Use lookup_attr() instead.
 *
 * ntfs_attr_find() takes a search context @ctx as parameter and searches the
 * mft record specified by @ctx->mrec, beginning at @ctx->attr, for an
 * attribute of @type, optionally @name and @val. If found, ntfs_attr_find()
 * returns 0 and @ctx->attr will point to the found attribute.
 *
 * If not found, ntfs_attr_find() returns -1, with errno set to ENOENT and
 * @ctx->attr will point to the attribute before which the attribute being
 * searched for would need to be inserted if such an action were to be desired.
 *
 * On actual error, ntfs_attr_find() returns -1 with errno set to the error
 * code but not to ENOENT.  In this case @ctx->attr is undefined and in
 * particular do not rely on it not changing.
 *
 * If @ctx->is_first is TRUE, the search begins with @ctx->attr itself. If it
 * is FALSE, the search begins after @ctx->attr.
 *
 * If @type is AT_UNUSED, return the first found attribute, i.e. one can
 * enumerate all attributes by setting @type to AT_UNUSED and then calling
 * ntfs_attr_find() repeatedly until it returns -1 with errno set to ENOENT to
 * indicate that there are no more entries. During the enumeration, each
 * successful call of ntfs_attr_find() will return the next attribute in the
 * mft record @ctx->mrec.
 *
 * If @type is AT_END, seek to the end and return -1 with errno set to ENOENT.
 * AT_END is not a valid attribute, its length is zero for example, thus it is
 * safer to return error instead of success in this case. This also allows us
 * to interoperate cleanly with ntfs_external_attr_find().
 *
 * If @name is AT_UNNAMED search for an unnamed attribute. If @name is present
 * but not AT_UNNAMED search for a named attribute matching @name. Otherwise,
 * match both named and unnamed attributes.
 *
 * If @ic is IGNORE_CASE, the @name comparison is not case sensitive and
 * @ctx->ntfs_ino must be set to the ntfs inode to which the mft record
 * @ctx->mrec belongs. This is so we can get at the ntfs volume and hence at
 * the upcase table. If @ic is CASE_SENSITIVE, the comparison is case
 * sensitive. When @name is present, @name_len is the @name length in Unicode
 * characters.
 *
 * If @name is not present (NULL), we assume that the unnamed attribute is
 * being searched for.
 *
 * Finally, the resident attribute value @val is looked for, if present.
 * If @val is not present (NULL), @val_len is ignored.
 *
 * ntfs_attr_find() only searches the specified mft record and it ignores the
 * presence of an attribute list attribute (unless it is the one being searched
 * for, obviously). If you need to take attribute lists into consideration, use
 * ntfs_attr_lookup() instead (see below). This also means that you cannot use
 * ntfs_attr_find() to search for extent records of non-resident attributes, as
 * extents with lowest_vcn != 0 are usually described by the attribute list
 * attribute only. - Note that it is possible that the first extent is only in
 * the attribute list while the last extent is in the base mft record, so don't
 * rely on being able to find the first extent in the base mft record.
 *
 * Warning: Never use @val when looking for attribute types which can be
 *	    non-resident as this most likely will result in a crash!

 *
 * If @name is AT_UNNAMED search for an unnamed attribute. If @name is present

 * this is the correct place to insert it into, and if there is not enough
