autofsv5 enhancement - map names in /proc/mounts

    The current entry which ends up in /proc/mounts for autofs entries 
looks like:

  automount /home autofs rw,fd=170,......

Other autofs implementations (Solaris, Irix, OSF1, ...) have the 
map-name which is being used as the first token.

The attached patch to daemon/indirect.c adds this (for indirect maps - I 
don't have any other kind...).

The result is lines like:

  auto.home /home autofs rw,fd=170,......


This does means that kernel mount entries (eg: those added under 
SElinux?) need to ignore the device name passed in, but they should be 
doing that for autofs file systems anyway.

NOTE: The ap->entry->first->argv[0] seems a contrived way to get a map 
name, but is all I could see looking through the code.
