Merged branches/bridge_bug_80217 into the trunk.

I have replaced C++ comments in C code with C code comments.

I have moved/changed variable declarations to not bream the ISO C90 rule
against mixed declarations and code.

Added switch in configuration file to decide whether or not the testsuite should be run.

Fixed ownership of converters. They are now completely owned by their conversion service and a reset of the conversion service will drop any converter it holds. On the way, dependency between services was implemented, where a service can register itself to any other one(s) and a reset call on one of these will trigger a reset of the registered service

Avoided the use of timeout gets on queues for efficiency reasons. Also cleaned up the termination code

Better implementation of ThreadPoolServer. The previous implementation was not allowing to have more clients connected than threads in the pool

Fixed output of listtransfers -p when there are 0 transfers. It was previously displaying '-' instead of 0 as if the information was not available.

sr #120838: Support for IBM TS1140 tape drive capacities

Added 4 new densities (1600G/GC, 4000G/GC) to add support for the IBM TS1140 family.
Created entries similar to the ones of the latest added density (5000G/GC).

and removed the unused index on gcWeight.

Added many hints for the subrequest table so that indexes are used properly. This was triggered by a case where ORACLE decided to do a full index scan rather than an index lookup because the number of items in the subrequest table was close to 0. This can seem ok, but led to a scan of many (empty) blocks, as the subrequest table had been big in the past and blocks are not reclaimed. As a consequence, the performance was degraded.

Improved efficiency of transferToSchedule PL/SQL function by adding an extra index on SubRequest table

Fixed deletion of DB related services when their associated conversion service is dropped and vice versa. Now the conversion service owns services using it, i.e. it will delete them when it is destrcuted.

Build both the stk and nostk tape server software in the same build process. This saves having to build the CASTOR software stack twice reducing build times by up to 50% (approx 5 minutes)
