Ticket #93 fix:
Exceptin handling re-written in assembly.

pillai
/branches/arm/kernel/arch/arm32/src/
Change the exception handling logic:
Exception handler switches from exception mode to kernel mode(supervisor mode) before proceeding to
the exc_dispatch() C function. This assures that exception handling is re-entrant and
kernel would not get confused with different processor modes inside the kernel.
Also fixes a kernel panic during nested interrupts.
