Subject: scripts/gdb: provide exception catching parser
If we attempt to read a value that is not available to GDB, an exception
is raised. Most of the time, this is a good thing; however on occasion we
will want to be able to determine if a symbol is available.
By catching the exception to simply return None, we can determine if we
tried to read an invalid value, without the exception taking our execution
context away from us
