[patch] Make 'info func' interruptible.

[ppluzhnikov@google.com (Paul Pluzhnikov)]

Greetings,

This is rather on the obvious side.

For a large (300MB) debug binary, doing 'info func' (without regex)
puts GDB into 10 minute uniterruptible 100% CPU spin.

While improving the 10 minute wait will hopefully be a subject of
another patch, attached patch makes the wait interruptible.

Thanks,
