Pretty straightforward changes. This commit tries to avoid making any non-trivial fixes.

Probably fix TLB shootdown "diagonal" livelock.
...
Diagonal as in
Thread A Thread B
Send to B Send to A
Wait for B Wait for A.
I haven't reproduced this bug, but this should fix it, since the wait
steps now checks the local percpu block for pending TLB shootdowns onto
itself.

Forbid strong fdtbl refs after setting context's.
...
This fixes a possible file table leak if a filetable contains an fd
referring (strongly) to the filetable itself. Now, it will automatically
be downgraded to a weak reference after it becomes a context's active
file table.
TODO: maybe support consuming a context's filetable to get a strong
reference back, provided it's exclusively owned.
