* a-elchha.adb, a-except-2005.adb, a-except.adb, a-exexda.adb,

Exception_Information is used to produce useful debugging
information for the programmer. However, it was also used to
implement the stream attributes for type Exception_Occurrence. The
latter requires a stable and portable interface, which meant
that we couldn't include a symbolic traceback. A separate set of
routines was used to provide symbolic tracebacks under program
control (i.e. not automatically). The goal of this ticket is
to provide such automatic tracebacks, so the change here is to
split the two functionalities: Exception_Information gives the
maximally useful information for debugging (i.e. it now includes
a symbolic traceback when a decorator is set, and it can be
improved freely in the future without disturbing streaming).
Untailored_Exception_Information always uses hexadecimal addresses
in the traceback, has a stable and portable output, and is now
used for streaming.
