R/O attribute when using ACLs.
(fhandler_disk_file::mkdir): Ditto. Set
security descriptor on remote dirs after creating the dir, same as in
fhandler_base::open.
* fhandler_socket.cc (fhandler_socket::bind): Ditto for remote AF_LOCAL
socket files.
* path.cc (symlink_worker): Ditto. for remote symlinks.
* security.cc (alloc_sd): Take additional path_conv argument.
Accommodate throughout. Drop setting FILE_WRITE_EA/FILE_READ_EA
flags unconditionally (was only necessary for "ntea"). Don't set
FILE_READ_ATTRIBUTES and FILE_WRITE_ATTRIBUTES unconditionally on
Samba. Add comment to explain. Drop useless setting of
STANDARD_RIGHTS_WRITE, it's in FILE_GENERIC_WRITE anyway.
Remove FILE_READ_ATTRIBUTES bit from FILE_GENERIC_EXECUTE so as not
to enforce read permissions on Samba.
(set_security_attribute): Take additional path_conv argument.
* security.h (set_security_attribute): Change prototype accordingly.
