This fixes UINT64_C not defined in SLC5.

For instance, we can now ensure client.reportEndOfSession(WithError) is the last function called and check we have the right number of report

ReportEndofSession(WithErrors)::goingToEnd returns now true as it should and RecallReportPacker.M-terminate has been removed by goingToEnd+break if true

Moved all files related to Client to client/, changed the namespace and fixed the files consequently (header,usings,...)

Modified the FakeClient consequently and the CMake files too

Relaxed constrain on frequency for flusing report and added logging&report to client in case of mismatch between the report's type for the end of session and the presence of an error
Now we call reportEndOfSessionWithErrors if there is an actual error or a mismatch (that implies a bug in the code). Flushing is done as soon as the number of reports is >= frequency (instead of >)

Add logging and report to client in case of mismatch between the report's type for the end of session and the presence of an error
Now we call reportEndOfSessionWithErrors if there is an actual error or a mismatch (that implies a bug in the code)

Removed the exception launcher which was not used anywhere and duplicates the one of castor::exception::Errnum.

TapeReadFileTask, TapeReadTask, TapeSingleThreadInterface,
TapeReadSingleThread, TapeWriteTask, TaskInjector

Fixed tapeserver-mm which makes use of some of the moved classes.

We currently only cover the Recalls, and we still need to start the threads.

intended for protyping.
Retyped DiskWriteThreadPool's members to fixed length types.

Recalled files are now logged and the list of reports is cleaned-up after reporting the statuses to the client

MigrationReportPackerTest.cpp and RecallTaskInjectorTest.cpp had both their FakeClient class (which was a waste of time). They now use the merged class which is FakeClient.hpp

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

log, client interface and m_listReports are now inherited from the base class

Also changed FakeClient classes into the tests files  to add an empty implementation of reportRecallResults

Eric found that the underlying C function getaddrinfo() is thread
safe because of RFC 3493.
