Added an std::exception::Backtrace class, providing a backtrace attached to all exception.
Fixed minor side effects (virtual destructors, catch orders) induced by the inheritance from std::exception.

C++ not be strict enough with the use of const.  I hope this commit fixes these
const problems.  There is still another SLC6 I need to tackle in order to get
TramCity to pass the SLC6 build.

until some work is pulled/rebased from the remote master.  Please also note
that more work still needs to be done before this can be used by somebody else.

the UUID should be passed in as a const.

Added a PackeOnly cmake mode to allow packaging in reduced environement (i.e. missing some build dependancies). This allows creation of tarball and srpms.

static (hidden) methods to the castor/log/Log.cpp file:

    castor_openlog()
    castor_closelog()
    castor_syslog()

These three methods are copies of the dlf_openlog(), dlf_closelog() and
dlf_syslog() functions defined in the file CASTOR/dlf/dlf_lib.c.  I have
renamed the associated static global variables using the "s_" naming convention.

Please note that this commit does not finish the implementation of the new
logging API (I here a groan from the back).  Again I'm looking for feedback
(again another groan from the back).

This commit provides an empty implementation.  It's goal it to agree upon the
API which is basically a cut down rip-off of the orginal DLF API.

Isn't DLF already dead? I here you cry, well in line with good CASTOR tradition
I reply both yes and no.  The server side of the Distributed Logging Facility,
effectionately known as the Denis Logging Facility, has been gone for a while.
However both the C and C++ APIs have remained, with the code implementing them
simply sending CASTOR logs to rsyslog.

I forgort to add it to the correct file in the debian directory.

build.

The tapegatewayd daemon no longer interprets python code and therefore does
not need to be linked with the python library.
