put parser, lexer, and evaluator in namespace; interpreter now owns evaluator
* oct-parse.in.yy, parse.h: Move parser classes to octave namespace.
* lex.ll, lex.h: Move lexer classes to octave namespace.
* pt-eval.h, pt-eval.cc: Move evaluator class to octave namespace.
Don't define global current evaluator pointer here.
* debug.cc, error.cc, input.cc, input.h, ls-mat-ascii.cc, pt-jit.cc,
sighandlers.cc, utils.cc, variables.cc, ov-usr-fcn.cc, pt-assign.cc,
pt-exp.h, pt-id.cc: Update for namespaces.
* interpreter.cc, interpreter.h (current_evaluator): New global var.
(interpreter::m_evaluator): New data member.
(interpreter::~interpreter): Delete evaluator.
