In the latest snapshot, there are two problems about handling
file attributes.

fhandler_disk_file::open desn't check the magic number '#!' on NT.
  if (!real_path.exec_p && os_being_run != winNT)

When NTEA is enabled, this causes no problem by doing chmod +x.
But when NTEA is disabled by default, I can't execute shell
scripts having the same name as .exe files in another path.
I think it should always check the magic number or not check
only when NTEA is enabled.

stat() system call about a symlink always returns st_mode having
S_IFLINK bit. This bug is caused by the constructor of path_conv
class. Whenever the src path is a symlink, It set symlink_p to
true regardless of the follow_mode.
The following patch works fine.
