bakpakin 6f1695ecd4 Add utitities for interrupting the event loop.
janet_loop1_interrupt makes the event loop compatible
with safe interruptions for custom scheduling. Does this by exposing
custom events on the event loop. A custom event schedules a function pointer
to run in a way that can interrupt
epoll_wait/poll/GetQueuedCompletionStatus.

bakpakin 160dd830a0 Add janet_interpreter_interrupt for custom scheduling.
This would allow an embedder to suspend the current Janet fiber
via an external event like a signal, other thread, or really anything.
This is a useful primitive for custom schedulers that would call
janet_interpreter_interupt periodically (say, in an interval with SIG_ALRM),
do some work, and then use janet_continue on the janet_root_fiber, or
for embedding into other soft-realtime applications like a game. To say,
only allow about 5ms per frame of interpreter time.

Calvin Rose 1ef6db16ed Add janet_vm_save and janet_vm_load.
This lets a user multiplex multiple Janet VMs on a single
thread or process if they are willing to implement context switching
themselves.
