Added const qualifiers where necessary to netwrite(), most importantly this function does not modify the contents of the buffer passed to it

Modified smc/Imakefile so that the link stage of the smc command-line tool
explicitly names libcastorcommon.so as a dependency.  The build process already
works due to some implicit symbol resolutions as link time.  This modification
makes the link logic easier for the reader to by making it explict.

Fixed in the trunk.

My previous commit was great if all you wanted to do was build CASTOR from the trunk directory.  Unfortunatley my previous commit is a failure if you wish to build CASTOR from a sub-directory.  Reverse merging my last commit in order to repair my mistake.

Fixed in the trunk.

Added the following two serrno entries:

ETINVALIDTFSEQ  (1939) Invalid tape-file sequence-number
ETINVALIDTFSIZE (1940) Invalid tape-file file-size

Added the new serrno number "ETSESSIONERROR (1938) Tape session error".

Reverted commit r25014

castor.localhosts and castor.remhosts files.

so that it's there in all cases.
Dropped sysconfig for security as already not supported/obsoleted.

Cleanup some more defects and especially got rid of lot of useless code around network releated functions

several small fixes for defects identified by Coverity. Mainly around uncaught exceptions and secure coding

many fixes of little issues found by the cppcheck tool. In particular, a few memory leak were discovered.

Added new tape errors to serrno manual page.

In order to improve logging for tape-operations and to facilitate the current
testing surrounding this bug, the serrno code of ENOMEM has been replaced by
the more specific error ETNOLBLINFOMEM meaning "No memory available for label
information" within the setlabelinfo function.

Fix which requires testing.

  - svcClass was dropped from the MigrationRouting table as unused. Tools have been amended accordingly.
  - MigrationJob has now an originalCopyNb and originalVID in case of repack migrations that allow to identify repacks properly
  - a table MigratedSegment has been added holding information on other existing tape segments for the migrating files. This allows to avoid putting 2 copies on a file on the same tape
  - in general, migrations that can be triggered at recall time (extra copy and repacks) are populated in MigrationJob table from the beginning, in status MIGRATIONJOB_WAITONRECALL. This allows easy triggering of the migrations after the recall and to identify any problematic migration routing before we even recall.

The main gains are :
  - simpler DB schema : StreamToTapeCopy and SvcClass2TapePool have disappeared. TapeCopy is split in to the dedicated RecallJob and MigrationJob. Stream is replaced by MigrationMount that includes all data needed from the Tape table (so the Tape table only used by recall now).
  - simpler concepts : MigrationMounts match with mounts and do not survive them (as Stream did), MigrationRouting table explicitely gives the migration routing. NbDrives has moved to the TapePool
  - less components : migHunter is gone, replaced by the MigrationRouting table and by a DB job that starts the needed mounts
  - better error reporting : migration failures due to bad configuration are reported sunchronously to the user, on file close or even on file opening when possible. e.g. if the combination of svcClass and fileClass given by the the user is not present in the MigrationRouting table, the file opening will fail with message "File recreation canceled since the file cannot be routed to tape". This case used to loop forever in the migration part.

The version is MUCH lighter than the previous one and consists only in a small python script talking to the stager DB.
In particular the repack DB and repack daemon are gone.
The handling of repack at the stager level has also be greatly improved, using bulk APIs and a direct access to the nameserver DB via DB link. The will make the repacking of tapes with > 1M files possible.

Merged v2_1_11Version-TapeBulkProtocols branch into trunk.
