Log Message:
-----------
Guile exception handling is written from scratch. We were just able to handle
exceptions raised at procedure execution, from now we'll be able to catch any
exception will be raised by Guile -- except it's raised from scm_init_guile(),
which is fortunately handled by PG_TRY().
Also, this will fix some redundant backtrace information display. Previously,
stack frame that is to be used to display backtrace information is not clear.
>From now, we're marking the stack `throw' called via pre-unwind exception
handlers.
