[PATCH] Display full file path in MI style disassembly listing

["Andrew Burgess" <aburgess at broadcom dot com>]

When producing an MI style disassembly listing we use the shorted symtab filename, rather than computing the fullname.  This can make it harder for an MI consumer to figure out which file to open.

The patch below tries to use the fullname when it can, and falls back to the shorter name if it can't figure out the full name.

Ok to apply?

Thanks,
Andrew
