[PATCH] udev - man page update

Here is a small change to the udev man page:

  - clarify the use of the NAME{all_partitions} syntax
    and add a example to udev.rules.example
  - mention the empty NAME field to ignore the device
  - prepare a SYMLINK field for the addition of Andrey's
    "multiple symlinks" documentation :)
