Repairs broken config parsing for FSAL_PROXY.

This commit repairs the broken config parsing for FSAL_PROXY.
The syntax for the proxy specific arguments is as follow:
PROXY
{
	# FSINFO arguments (cansettime, link_support, ...
	(..)
        Remote_Server
        {
                Srv_Addr = server.remote.net ;
                Retry_SleepTime = 10;
                Use_Privileged_Client_Port = true;
		(...)
        }
}

Lustre/PNFS: refurbishes the :Lustre/pNFS configuration

This commit changes the way pNFS configuration is managed.
The pNFS configuration is no more a dedicated LUSTRE_PNFS block.
The configuration goes into a sub-block of FSAL dedicated configuration
block "LUSTRE"

The syntax becomes:
LUSTRE
{
	# fsalfsinfo related items
	xattr_access_rights = 0700;
	(...)

	PNFS
	{
            DATASERVER
            {
                    DS_Addr = ganesha_ds2.mynetwork.myhome ;
                    DS_Port = 2049 ;
                    DS_Id = 1 ;
            }
            DATASERVER
            {
                    DS_Addr = ganesha_ds2.mynetwork.myhome ;
                    DS_Port = 2049 ;
                    DS_Id = 2 ;
	    }
	  #more Dataservers if wantred
	  (...)
	}
}

Export specific configuration remain the same:
    EXPORT
    {
      (...)
      FSAL {
        name = "LUSTRE";
        PNFS
         {
            Stripe_Unit = 1048576;
            pnfs_enabled = true;
            DATASERVER
            {
                    DS_Id = 2 ;
            }
            DATASERVER
            {
                    DS_Id = 1 ;
            }
         }
      }
     (...)

IMPORTANT REMINDER:
On each pNFS data server, a "pNFS aware" ganesha server should run.
pNFS can be enabled for some exports and disabled for others.
Different exports can use different sets of DSs.

FSAL_LUSTRE: fixes CID24050 (unchecked return code)

Comments useless code. This code will be uncommented as code will be added in the config's commit functions.

FSAL_PROXY and FSAL_LUSTRE have block with *_commit functions, to be called during parsing to check configuration item.
Those functions are currently empty are are basically placeholders.
Setting a variable withut using it triggers a compilation error in Maintainer mode, so I commented this.
This piece of code will be uncommented as "flesh" will come in this part of the code.

Exports configuration: adds "All Anonymous" as an synonym for "All Squash"

The Squash=All statement replaces the old "ALL_ANONYMOUS" from older configuration file.
Adding Squash=All_Anonymous makes the change more intuitive to sysadms.

Explicitly ignore result of display_printf

When constructing a log message, we can ignore the result of display_printf
since we want to print the message even if it should happen to be truncated.

Attempt to only add one client to export per entry (fixes BZ 1074481)

The client list was adding two entries for each possible address because
getaddrinfo shows an entry for both UDP and TCP. A simple check is to keep
track of the last address added, and not add it again. This should eliminate
all the duplicates (especially if JUST an ip address is given in which case
the addrinfo will ONLY return those two entries).

Also for showmount -e report the Wildcard and IPv6 addresses not as
unknown.
