2011-06-13disable interrupts when switching from undef handler to debuggerTat-Chee Wan (USM)
NxOS has nested interrupts support. Prevent accidental retriggering of UNDEF handler while processing an existing breakpoint by disabling interrupts until the breakpoint has been restored and the debugger is really ready to handle debug messages.

2011-04-01refactored message ack or nak routines to always send a reply to any gdb messageTat-Chee Wan (USM)
For GDB commands such as Continue or Step, no reply is expected. However, the GDB server needs to receive a reply to avoid hanging the read() command on the Host side. Consequently these 2 commands now send an Ack (no message) to keep the GDB server happy.
