8286b33c52 Add event-chan argument to ev/go. 
The event-chan is the final piece of the puzzle for fibers, and
will be pushed to when a fiber yields to the event loop.

475775cc9d Add a "new_channel" for root fibers. 
When new fibers are scheduled on the event loop, this new_channel
receives the newly created fibers. This lets a fiber track which fibers
have been added and let's a user implement a supervisor.

Fix formatting.

4e7ad3c7ce Add initial implementation for supervisor channels. 
Supervisor channels are a simple concept to more efficiently
enable dynamic, structure concurrency. When a top-level fiber
completes (or errors), it will push itself to it's supervisor
channel if it has one (instead of printing a stacktrace). This
let's another fiber poll a channel and "supervise" a set of fibers.

adc41e31f4 Address #547 - don't drop references. 
Keep a separate stack for tagged references. May cause pegs to
use more memory but makes the backref and backmatch features much more
powerful.

Also disables the second stack if backref and backmatch are not used in the peg.

0a1c93b869 Add ev api for making threaded calls. 
Easy way to make arbitrary functions in C async.

cbdea8f331 Make os/execute cooperate with ev module. 
os/execute, os/proc-wait do not block (currently posix only).
This uses the self-pipe trick to turn signals into a pollable entity.

776ce586bc Add line and column combinators to peg. 
These capture the line and column number of the current position
in the matched text. This is useful for error reporting as well
as indentation checking.

This works by lazily creating an index on first use that stores all
newline character indices in order. We can then do a binary search on
this to get both line number and column number in log(n) time.
This is good enough for most use cases and doesn't slow down the common case at all
- these will not be commonly used patterns in a hot loop so it is not worth to try and
optimize this at all. Constant time look up should be possible but at
the cost of complicating code and slowing down all matching to check for
new lines.

d6391f2d70 Get windows IOCP working for accept. 
This also changes the api of servers slightly -
in light of having support for ev tasks, it is probably better
to remove the "simple" server code and replace it with some Janet
or remove it all together. While convenient, it has issues with error
handling and rigidity.

d3147b661b Add :pipe to os/spawn for piping to subprocess. 
Similar to Python's subprocess.PIPE, this creates and manages pipes
automatically for the caller.

24b8b0e382 Fix NaNboxing bug that cause flaky builds. 
The macro janet_checktype(x, JANET_NUMBER) was incorrect when
x was NaN. This caused the initial unmarshalling dictionary to be missing
entries in certain cases.

fb26c9b2c4 Add ev/select and ev/rselect initial implementation. 
Getting closer to a CSP implmententation. Probably
useful to move scheduling fields outside of fibers
and into an external table.

ba08e487cb Disable PRF by default. 
Since it is not any better by default without initializing the key, we
disable it by default. It can be turned on with JANET_PRF in
janetconf.h.
