1) Changes codes for performance and request's costs
s3fs gets object's attributes by using HEAD request.
Directory objects is following 4 type:
a) name type is "dir", with meta information
b) name type is "dir", without meta information(but has files in itself)
c) name type is "dir/", with(out) meta information
d) name type is "dir_$folder$", with(out) meta information
The codes is changed to order checking directory object.
So that, s3fs decreases requests for checking objects.
Before version has a bug, that is s3fs can not be recognizable type-b)
definitely when s3fs check the object directly.(but s3fs can, when s3fs
check the object by listing)
This change fixes this bug.
2) Adds "multireq_max" option
Added "multireq_max" option is maximum number of parallel request
for listing objects.
This changes is possible to solve CURLE_COULDNT_CONNECT.
If this option can not solve it, this option will be useful for tuning
performance by each.

1) Fixed a bug(forgot removing temporary files)
When s3fs gets a error from fwrite in multipart uploading function,
s3fs does not remove a temporary file.
2) Fixed a bug(wrong prototype of function)
The prototype of function for CURLSHOPT_UNLOCKFUNC
is wrong.
3) Changed codes
- In my_curl_easy_perform function, the codes for debugging messages
is changed, because it is for not working codes when "-d" option is
not specified.
- Changes struct head_data's member variables, and some codes for this
changes.
- Moving calling function to main for curl_global_init and curl_share_init
functions, because these function must call in main thread.
4) Fixed a bug(use uninitialized memory)
In get_lastmodified function, this function does not initialize value
(struct tm).
5) Fixed a bug(access freed variable)
In readdir_multi_head function, access a variable which is already freed.

1) Patch adding support for SSE( Issue 226 )
Supports SSE(Server-Side Encryption) and adds "use_sse" option.
* Specifications
When "use_sse" option is specified as "1", s3fs adds "x-amz-server-side-encryption"
header as "AES256".
But it only does when objects upload(writing object).
When you do chmod/chown/chgrp/touch/mv commands, s3fs does not
add this header and inherit SSE mode from oroginal object.
* Notice
"use_sse" option can not specify with "use_rrs" because we get signature
error from S3.

1) s3fs should cache DNS lookups?(Issue 304)
Changes that s3fs always uses own dns cache, and adds "nodnscache" option.
If "nodnscache" is specified, s3fs does not use dns cache as before.
s3fs keeps DNS cache for 60 senconds by libcurl's default.

1) Fixes a bug which object owner/group is set wrong id.
When do chown(chgrp) command without group(owner), s3fs set wrong id(-1)
for group(owner) id.
Fixes this bug.
2) The permission of mount point when allow_other option is specified.
When allow_other option is specified, s3fs forces the mount point directory
permission to set executable permission(mode | 0111).
3) Fixes a bug about permission
For example, when the directory permission is 0557, other user(who is not owner
and same group) gets a permission error when making file or directory in that dir.
Fixes this bug.
4) Compile error: blkcnt_t(Issue 340)
Fixes a bug: Compile error: blkcnt_t(Issue 340)

1) Adds enable_content_md5 option
When s3fs uploads large object(over 20MB), s3fs checks always ETag(MD5) in each multipart's response.
But for small objects, s3fs does not check MD5.
This new option enables for checking MD5 of uploading object.
If "enable_content_md5" option is specified, s3fs puts the object with "Content-MD5" header.
The checking MD5 value is not default, because it increases some of user's cpu usage.
(The default value may be replaced in the future.)

1) s3sync'ed files not supported(Issue 31)
Supports HTTP headers which made by s3sync.
Supported new HTTP headers are x-amz-meta-owner,
x-amz-meta-permissions and x-amz-meta-group.
s3fs read and understand these headers, but s3fs
gives priority to s3fs's headers over these headers.
2) Cleanups codes
Cleanups some codes about issue 31.

1) Man file has wrong permissions for passwd file(Issue 291)
Fixes man page for wrong permissions of passwd file.
2) Fixes a bug and Strictly checks passwd file permission.
* Fixes a bug about checking passwd file permission.
A bug is that s3fs continues to run after s3fs finds invalid passwd
file permission.
* Checks passwd file strictly.
Before this revision, s3fs allows executable permission for a
passwd file and allows group writable permission for a passwd
file(which is not "/etc/passwd-s3fs").
New s3fs checks permission strictly, that is /etc/passwd-s3fs is
allowed owner readable/writable and group readable, and the
passwd file(which is not "/etc/passwd-s3fs") is allowed only owner
readable/writable.
3) Adds disable_noobj_cache option for no-existing object.
s3fs v1.68 always has to check whether file(or sub directory) exists
under object(path) when s3fs does some command, since s3fs has
recognized a directory which does not exist and has files or sub
directories under itself.
It increases ListBucket request and makes performance bad.
For performance if the disable_noobj_cache option is specified, s3fs
memorizes in stat cache that the object(file or directory) does not exist.

1) Feature Request: Compatability with other S3FS clients(Issue: 27)
Rechanges source code.
2) For other S3 clients
Supports the directory which is no objects.
If there is a object which has "/" charactor(ex. "<bucket>/dir/file"), the directory("dir") object is no object.
Exsample, you can upload the object which name is "s3://bucket/dir/file" by the s3cmd.
Then the "dir" is not object in bucket("dir").
This s3fs codes understands this case.

1) Feature Request: Compatability with other S3FS clients(Issue: 27)
Supported the directory object which made by s3fox. Its name has "_$folder$" suffixes.
On s3fs, that directory object is listed normal directory name without "_$folder$".
You need careful when you change object attributes(rename, chmod, chown, touch), because the s3fs remakes the directory object after that object(which has "_$folder$" suffix)
After changing the object attributes, the object name does not have "_$folder$" suffix.
It means the object is remade by s3fs.
2) Other
Fixes bugs which are found when this issue is fixed.

The return value in get_username() function is wrong value(NULL) when there is not user id in passwd file.

==========================
List of Changes
==========================
1) Fixes bugs
Fixes Issue 321: "no write permission for non-root user".
(http://code.google.com/p/s3fs/issues/detail?id=321)
Fixes a bug which s3fs does not set uid/gid headers when making symlink.
2) Cleanup code.
Adds a common function which converts the Last-Modified header to utime.
Deletes the useless cord and arranged it.
3) xmlns
Changes that s3fs can decide using the xmlns url automatically.
Then the noxmlns option is not needed anymore, but it is left.
4) Changes cache for performance
Changes stat cache, it accumulates stat information and some headers.
By adding some headers into cache, s3fs does not need to call curl_get_headers function.
After changing, one cache entry increases in about 500 bytes from about 144 byte.
Adds one condition to get out of the cache, that condition is by looking object's ETag.
It works good for noticing changes about obojects.

No changes for logic, only changes layout of functions and valiables between a file to a file.
Adds s3fs_util.cpp/s3fs_util.h/common.h
