[esnacc-dev] [PATCH] cxx-lib: do not use exceptions in performance critical operators

In asn-buf.cpp the operator<() and the operator==() methods 
suffer from a performance issue, they are running in a loop until 
an exception is not thrown. This is a very bad idea, and very 
inefficient way of error handling. I have done some performance 
tests with gproof. The performance has improved about 4 times better, 
the code runs faster after my fix. I removed the exception handling from 
operator<() and the operator==() and replaced them to a 
boolean function, that can signal if an exception would be thrown.
