f9ab91511d peg: add support for "true" and "false" primitives to always/never match 
The use cases involve user-expandable grammars.
For example, consider the IRC nickname specification.
> They SHOULD NOT contain any dot character ('.', 0x2E).
> Servers MAY have additional implementation-specific nickname restrictions.

To implement this, we can do something along these lines:
```janet
(def nickname @{:main '(some :allowed)
                :allowed (! (+ :forbidden/dot :forbidden/user))
	        # for lax mode, (put nickname :forbidden/dot false)
	        :forbidden/dot "."
		# to add your own requirements
		# (put nickname :forbidden/user 'something)
		:forbidden/user false})
```

Additionally, it's common in parsing theory to allow matches of the
empty string (epsilon). `true` essentially allows for this.

Note that this does not strictly add new functionality, you could
emulate this previously using `0` and `(! 0)` respectively, but this
should be faster and more intuitive.
The speed improvement primarily comes from `(! 0)` which is now a single
step.

57c954783d Fix resumption values when closing a channel. 
When suspended in `ev/give` or `ev/take`, closing the channel should
cause the result of `ev/give` or `ev/take` to be `nil`.

When suspended in `ev/select`, closing the channel should cause the
result of `ev/select` to be `[:close ch]`.

The results were flipped before.

4b3c813f5a Revert to old behavior of janet_fiber returning NULL. 
When there is a bad arity function passed in to the fiber
constructor, return NULL so the runtime can choose what to do.
This is not the prettiest API but does work, and gives better error
messages for instance in the compiler.

e97299fc65 Fix #1174 - bad debug info causing stack traversal to segfault. 
Coming from commit 77189b6e66, relating
to changes in source mapping debug info, this caused a segfault when
traversing a stack frame where the birth_pc was incredibly large due
to wrap around. This fix prevents the wrap around and does saturating
subtraction to 0.
