This unfortunate move is necessary because the error/exception
handling of rmcd is done using the TCP/IP connection with the
client.

The following two log snippets show that after retrying a mount
several times and finally succeeding, there is still the error
"rmc_sendrep: RMC02 - send error : No such file or directory".
This commit adds more logs to try an determine what is happening.

Found and removed some left over manual page text that still
referred to the RMC/HOST configuration parameter.

There will be separate rmcd and acsd daemons, therefore
removing the need for an rmcd "super-daemon" that does both
SCSI and ACS.

Fixed.

The current rmcd daemon only does SCSI compatible actions.  The future
rmcd daemon will be able to do both SCSI compatible and ACS
compatible actions.  I have therefore added the SCSI qualifier to the
"old" rmcd message constants to differentiate them from the ACS
message constants.

Fixed in the trunk ready for the version 2.1.15.x release of CASTOR.

Fixed in the trunk ready for CASTOR 2.1.15.x release.

The Rmc class is currently empty.  It will eventually become a proxy class
for communicating with the rmcd daemon over the network.

Fixed h/rfcntl.h which missed multiple inclusion guards entirely.

I introduced a bug into sstrerror() when I added error checking code
around the call to Cglobals_get().  The hash of the offending commit is:

ff8021a2

Before my so say improvements, the return value of Cglobals_get() was
not checked.  I added a check that assumed an error had occured if the
return value was non-zero.  Unfortuntaley for me, the return values 0
and 1 both mean success.  A return value of -1 signifies a failure.

With this commit tapeserverd connects to the vdqm using Cgethostbyname().
It is planned to replace this use of Cgethostbyname() by getAddrInfo().
