[Samba] recycle bin

[Franz Strebel]

1.  No need to pass anything to configure, it is now built
by default.

2.  Sample from my smb.conf

   vfs objects = recycle
   recycle:repository = ../recycle/%U
   recycle:keeptree = true
   recycle:versions = true
   recycle:touch = true
   recycle:exclude = *.tmp,*.temp,~$*,*.$$$,*.ldb

I'm running into problems with the exclude parameter though,
it seems to be ignored.  Will start a new thread for it.

Regards,
Franz
