gdb: add setting to disable reading source code files
In some situations it is possible that a user might not want GDB to try and access source code files, for example, the source code might be stored on a slow to access network file system. It is almost certainly possible that using some combination of 'set directories' and/or 'set substitute-path' a user can trick GDB into being unable to find the source files, but this feels like a rather crude way to solve the problem. In this commit a new option is add that stops GDB from opening and reading the source files. A user can run with source code reading disabled if this is required, then re-enable later if they decide that they now want to view the source code.
