4019,improve interprocess exception what() string,Marty Olevitch <marty@…>,Ion Gaztañaga,"Dear Ion,

I am planning to use your message_queues in new project and like it.
However, I find the exception messages not very useful.

One problem may be that in interprocess/exception.hpp, the
constructor
    interprocess_exception(error_code_t ec = other_error )
always sets the m_str value (which is returned by the what() member
function) to the same phrase
    boost::interprocess_exception::library_error

Better would be something that is appropriate for each type
of error, for example:
    message_queue receive: buffer_size (1) < max_msg_size (100)

There are only a few places where exceptions are thrown in
message_queue.hpp. Would it be possible to have for each of them more
useful error messages for the what() strings?
