1) Lifetime for the stats cache
Added the new option "stat_cache_expire".
This option which is specified by seconds means the lifetime for each stats cache entry.
If this option is not specified, the stats cache is kept in s3fs process until the stats cache grown to maximum size. (default)
If this option is specified, the stats cache entry is out from the memory when the entry expires time.
2) Enable file permission
s3fs before 1.62 did not consider the file access permission.
s3fs after this version can consider it.
For access permission, the s3fs_getattr() function was divided into sub function which can check the file access permission.
It is like access() function.
And the function calling the s3fs_getattr() calls this new sub function instead of s3fs_getattr().
Last the s3fs_opendir() function which is called by FUSE was added for checking directory access permission when listing the files in directory.
3) UID/GUID
When a file or a directory was created, the s3fs could not set the UID/GID as the user who executed a command.
(Almost the UID/GID are root, because the s3fs run by root.)
After this version, the s3fs set correct UID/GID as the user who executes the commond.
4) About the mtime
If the object does not have "x-amz-meta-mtime" meta, the s3fs uses the "Last-Modified" header instead of it.
But the s3fs had a bug in this code, and this version fixed this bug.
When user modified the file, the s3fs did not update the mtime of the file.
This version fixed this bug.
In the get_local_fd() function, the local file's mtime was changed only when s3fs run with "use_cache" option.
This version always updates the mtime whether the local cache file is used or not.
And s3fs_flush ( ) function set the mtime of local cache file from S3 object mtime, but it was wrong .
This version is that the s3fs_flush ( ) changes the mtime of S3 object from the local cache file or the tmpfile .
The s3fs cuts some requests, because the s3fs can always check mtime whether the s3fs uses or does not use the local cache file.
5) A case of no "x-amz-meta-mode"
If the object did not have "x-amz-meta-mtime" mete, the s3fs recognized the file as not regular file.
After this version, the s3fs recognizes the file as regular file.
6) "." and ".." directory
The s3fs_readdir() did not return "X" and "XX" directory name.
After this version, the s3fs is changed that it returns "X" and "XX".
Example, the result of "ls" lists "X" and "XX" directory.
7) Fixed a bug
The insert_object() had a bug, and it is fixed.

complete s3fs_readdir() refactor
- multi interface now batches HTTP requests
- proper HTTP KeepAlive sessions are back! (CURLOPT_FORBID_REUSE is no longer required)
- use xpath to quickly grab xml nodes
- lots of cleanup
- fixes some strange stat cache behavior
- huge readdir performance benefits (8-14x in my case) on large directories

- s3fs_flush() now checks to see whether the file on the remote end is the same as the local copy.
- md5sum() now requires a file descriptor instead of a path.

Functional changes are limited to the multipart upload process. Each uploaded part is now verified against a local md5sum.

- handle the curle_couldnt_resolve_host error better
- add the curl forbid reuse option

Beginning of s3fs "utility" mode - initially -u option
just reports in progress multipart uploads for the
bucket. Eventually this mode could be used for
other S3 tasks not accessible through typical
file system operations
For multipart upload, use safer mkstemp() instead
of tmpnam() for temporary file
Increased the curl connect and readwrite timeouts
to 10 and 30 seconds respectively.
Autodetect when a big file is being uploaded,
increase the readwrite timeout to 120 seconds. This
was found through experimentation. When uploading
a big file, it is suspected that time is needed
for S3 to assemble the file before it is available
for access. It was found that when a large file
was uploaded via rsync, the final mtime and
chmod modifications were timing out, even though
the upload itself was successful.
Multipart upload is ready for use. A couple of
error checks are still needed in the function and
some cleanup. Need some feedback on how it
is working though.

Check issue #142 for details
Code is operational, but not quite ready for
prime time -- needs some clean up

refactoring easier and the code easier to understand (for me anyway)
Opened up the VERIFY macro so that memory cleanup can be done
before returning from a function.
Make the file descriptor function calls a bit more robust,
check the return codes.

Rather than erroring out, it is treated like the
CURLE_OPERATION_TIMEOUT in that it doesn't exit the
timeout loop while the retry count is > 0. I
also added a short duration sleep to not retry
immediately.

failed. Most common reasons are the "time too skewed" or
credentials failure.
This could be extended to the curl routine that is used
during normal operation. However, the check_service routine
is a good first pass.

If the issue is seen, emit an informational message
and give the user an option to over-ride checking of
