fuse: interrupt handling framework
- add sub-framework to send timed responses to kernel
- add interrupt handler queue
- implement INTERRUPT
fuse_interrupt looks up handlers for interrupted messages
in the queue. If found, it invokes the handler function.
Else responds with EAGAIN with a delay.
See spec at
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/filesystems/fuse.txt?h=v4.17#n148
and explanation in comments.
