 This ticket is a result of the cppcheck warning:
 {{{
 src/lib/dhcpsrv/dhcp_parsers.cc:54: check_fail: Member variable
 'ParserContext::hooks_libraries_' is not initialized in the constructor.
 (warning,uninitMemberVar)
 src/lib/dhcpsrv/dhcp_parsers.cc:65: check_fail: Member variable
 'ParserContext::hooks_libraries_' is not assigned a value in
 'ParserContext::operator='. (warning,operatorEqVarError)
 }}}

 which occurred here:
 http://git.bind10.isc.org/~tester/builder/BIND10-cppcheck/20130817040001-FreeBSD8-amd64-GCC/logs/cppcheck.out

 When working on the resolution, it turned out that the copy constructor
 and assignment operator do not deal with the NULL pointers. It also
 occurred that there were no unit tests for the !ParserContext class. With
 this ticket the missing tests have been added.
