that is carried out when the method checks that the child has successfully
detached from the parent by making sure the return value of getppid() is 1.

I have removed the sanity check because it is time dependent.  If the child
calls getppid() before the parent has enough time to exit then the child
gets the process ID of its true parent as opposed to the process ID of the
init process.

castor/server/Daemon.cpp and castor/tape/tapeserver/daemon/tapeserverd.cpp.

of the following class:

    castor::server::Daemon

Subclasses now have a more explicit API for parsing the command-line.  They
can delegate the task to the above Daemon class or they can implement there own
parsing logic.  In the latter case the subclass must call the following
Daemon method:

    castor::server::Daemon::setCommandLineParsed(bool foreground);

This method makes it clear what the Daemon class needs to know from a parse of
the command-line.  If a client subclass calls the getForeground() method of the
Daemon class before callng setCommandLineParsed() then a CommandLineNotParsed
exception shall be raised.

objects representing standard in and standard error.

By being able to provide dummy output stream objects, this modification allows
C++ daemon objects to be instantiated in unit tests without the worry of them
writing to the real standard in and standard error streams.

    castor::server::Daemon

SLC5 so I unfortunatley have to lean on TeamCity for this.

tape bridge and vdqm daemons will eventaully inherit from one of these new
classes.  This commit is a step towards this goal.  Please note that this
commit modifies the castor::rh::Server and castor::server::BaseDaemon classes
in not so desirable ways.  The castor::rh::Server has been modified so that it
does not use the MetricCollector class.  The castor::server::BaseDaemon class
has been modified so that it does not use either the UDPListenerThreadPool or
the MetricCollector class.  I will put back this code in another commit.

CASTOR framework via the class castor::server:BaseServer.

Constructive feedback, and better still modifications, are warmly welcomed.

LoggerImplementation.  This then allowed me to rename the writeMsg()
suit of functions to logMsg() which is much more clear.

as a parameter.  The functions that create the CASTOR daemon objects all
create a castor::log::LogImplementation object and pass it to the constructor
of their corresponding CASTOR daemon object.  When unit testting, one now has
the posibility to develop a dummy Log object that implements the interface
with dummy or mock routines so that the unit tests can run without having to
write to syslog or rsyslog which is a bit heavy for unit tests.  The
castor::log::LogImplementation basically contains the logging code centered
around syslog that was developed by Sebastien and Dennis.

Please note that I now have to add one or more log functions to the base
class of the CASTOR daemon objects, namely castor::server::BaseServer.

+ some small improvements. Highlights:
- BaseThreadPool exposes internal metrics, which
  are collected by DynamicThreadPools and SignalThreadPools
- Internal monitoring can be enabled by command line
  for any daemon

a daemon may lead to bogus insertions in the list of thread pools,
which then provoke segmentation faults once the threads are started.

Updated to support removal of message service related code. Now all calls to clog() have been replaced with calls to dlf_writep()

so it is useless to free it only on the calling thread and it has the
bad side effect of leaving dangling pointers (see the DbCnvSvc destructor).

  castor::server::BaseServer::dlfInit(castor::dlf::Message messages[])

by adding:

  throw (castor::exception::Exception)

The implementation of this method calls the following method without
a try and catch clause around it:

  castor::dlf::dlf_init(const char* facilityName, Message messages[])

This method can throw a castor::exception::Exception.

Added initialization of the m_runAsStagerSuperuser boolean attribute to false. Prior to this all daemons were running accidentally under stage:st. As a consequence the jobManager was no longer able to submit jobs into LSF

UDPListenerThreadPool dedicated to dispatch UDP notifications.

Fixed 'uninitialized bytes' warning in the sendNotification method. Also added reset of the Cgetopt interface before parsing command line options. This allows daemons to process command line options without the need to override the parseCommandLine method i.e. a daemon can process its application specific options and the BaseServer can deal with the defaults
