Added more diagnostic output and debug functionality, e.g. regarding how many directory caches are currently being used. Long name directory scanning is a bit more paranoid when retrying a scan operation which might have been triggered by the server connection getting dropped. Added the new READONLY option (why stop at 47 options when you can have 48?) which makes the file system read-only by default and does not require you to use the "Lock" shell command to achieve the same effect. Note that the shell "Lock" command cannot be used to turn the read-only mode off again. Added support for the smb:// URI scheme, which means that instead of using "smbfs username=barney password=secret domain=workgroup //nas:445/share" you can now use "smbfs smb://workgroup;barney:secret@nas:445/share" instead. It is a bit shorter than the alternative and has an advantage in allowing you to reuse smb:// URLs which you know work well on other systems.
