of log to avoid truncation.

Added access to the undelying log object in LogContext to allow implementation
of logBacktrace (which logs without any extra context).

Moved the replacement of spaces with underscore inside the conditional
part of cleanString.

file description with structures from messages.

Simplified the interface of  HeaderChecker::checkHeaderNumericalField.

Fixed some header checkers where hex format was used instead of decimal.

Added healer functions to manipulate the blockIds.

The new functionnality allows reading of tape blocks into the MemBlock. The size
of the tape blocks is managed here.

Only affects the debuf version with file and line numbers.

The upcoming modofication will change the tape file interface, switching from the ad-hoc Fileinfo structure
to just using the structure from the network messages directly. We will not update those little used test programs.

This will impact the unit tests and make them more talking, showing
the logs as they come. We might want to make this behavior optional
in the long run (to limit the logs in the automatic builds).

Fixed comment: the default serrno for castor::exception::Exception(std::string) is SEINTERNAL, not  0.

RecallMemoryManager is the memory manager dedicated to the recall. All recall-related files are now using RecallMemoryManager

Thus, threads' begins and ends are logged with the threadID

Some ambigous namespaces no well supported by g++ 4.1

And removed functions that were previously removed from DiskWriteTaskInterface

Conditions were misaligned inside WorkerThread::run and a MutexLock was missing at the begining of the finish function

files,blocks and waitCompletion have been dropped out

Changed consequently the types to use the interface instead of the derived type : RecallReportPacker

DiskReadThreadPool::WorkerThread::run has been changed consequently

 thus if m_failled is set at true, then the block is not usable

That way, the LogContext is no longer shared between different threads
