1) Fixed a memory leak and un-closed file discriptor.

Browse Source 
2) Added a static table for file discriptors and paths which is keeped until closing.
   The s3fs_xxxx function called by FUSE is able to use a file disctiptor which is already opened by s3fs_open function.
3) The mknod is changed that it always return error, because it does not work through a network.
4) The symbolic file attribute changed to S_IFLNK | S_IRWXU | S_IRWXG | S_IRWXO.
5) Fixed the truncate function to work.
6) The mkdir and clone_directory_object functions are simplified and are changed to use the common create_directory_object function for these.
   For fixed a bug that the directory's PID/UID/mode are changed when these are  renamed.
7) The get_object_name function is changed to check a object finely. 
8) The s3fs_check_service function is changed for "301" response code.
9) Added the noxmlns option for a case of the response without xmlns field. (for the storage compatible with S3)
10) Added the nocopyapi option for the storage compatible with S3 without copy API.

* Comments 
  No.9 and No.10 are for the storage compatible with AWS S3.
  Both option are unnecessary options for AWS S3.
  In future, for the s3fs's promotion and possibility I would like to add new function.

disable registing xml name space for response of ListBucketResult and ListVersionsResult etc. Default name space is looked up from "http://s3.amazonaws.com/doc/2006-03-01".

\fB\-o\fR nocopyapi - for other incomplete compatibility object storage.
For a distributed object storage which is compatibility S3 API without PUT(copy api).
If you set this option, s3fs do not use PUT with "x-amz-copy-source"(copy api). Because traffic is increased 2-3 times by this option, we do not recommend this.
.SH FUSE/MOUNT OPTIONS
.TP
Most of the generic mount options described in 'man mount' are supported (ro, rw, suid, nosuid, dev, nodev, exec, noexec, atime, noatime, sync async, dirsync). Filesystems are mounted with '-onodev,nosuid' by default, which can only be overridden by a privileged user.
