[PATCH] Re: fruit_rename() prepend ._ again if fruit:ressource=file

Hello list,

Test master (4.7.0pre1-GIT-bcfa12c) also has this symptom,
refer to attach gdb log,
1st rename() and 2nd rename() are came from fruit_rename(),
which call SMB_VFS_NEXT_RENAME() twice.

Attached patch could address this issue,
this patch checks if the source appledouble basname matched
the destination basename; if they are matched,
would goto done and avoid 2nd rename().
Please help review and any suggestions are appreciated,
thank you.

For example,
a text file called "newfile.txt",
and win8.1 windows explorer renamed it to "._newfile.txt".
In fruit_rename(),
1. The 1st SMB_VFS_NEXT_RENAME() do rename:
   ./newfile.txt -> ./_.newfile.txt
2. Then this patch check and found that the source appbledouble
   basename (._newfile.txt) matched the destination basename
   (._newfile.txt), would goto done.
   Hence the 2nd SMB_VFS_NEXT_RENAME() is not called.

Here is the smb.conf
[global]
fruit:nfs_aces = no
fruit:veto_appledouble = no
vfs objects =  shadow_copy2 catia fruit streams_depot aio_pthread
