Jeremy Allison 0519088c53 s3: smbd: Change the function signature of srvstr_push() from returning a length to returning an NTSTATUS with a length param.
srvstr_push_fn() now returns an NTSTATUS reporting any
string conversion failure.

We need to get serious about returning character set conversion errors
inside smbd.

Bug 10775 - smbd crashes when accessing garbage filenames
