a87015598c Make janet_equals and janet_compare non recursive
This makes these operatios use constant stack space rather
than linear stackspace given the size of the inputs. This is important
to prevent certain parser input from causing a stack overflow - in
general, we try to avoid unbounded recursion.

72beeeeaaa Move funcenv verification to runtime.
Lazy verification makes it easier to not leave funcenvs
in an invalid state, as well as be more precise with the validation.
We needed to verify the FuncEnvs actually pointed to a stack frame if
they were of the "on-stack" variant. There was some minor checking
before, but it was not enough to prevent func envs from pointing to
memory that was off of the fiber stack, overlapping stack frames, etc.

fac47e8ecb When marshalling a closure, try to detach funcenvs
If possible, this will reduce the need to marshal fibers

to hang around forever.

f4d7fd97f6 Working TCP echo server and client.
Required a few changes to APIs, namely janet_root_fiber()
to get topmost fiber that is active in the current scheduler.
This is distinct from janet_current_fiber(), which gets the bottom
most fiber in the fiber stack - it might have a parent, and so cannot
be reliably resumed.
This is the kind of situation that makes symmetric coroutines more
attractive.

7c92c64730 Remove mutable operators on inttypes.
Mutations break hash table invariants, are a rather
silly performance optimization for a language like Janet.

46f57f5c38 Make file/close idempotent.
It is easier to use constructs like defer
with complex control flow if it is safe to close
a file twice.

2dd852da54 Use ATEND macros to add fields to abstract types.
This means we can add new properties to abstract types without
breaking old code. We can also make simple abstract types without
needing to add many NULL fields to the type.

f4ad627b54 Fix regression in while loops inside each macros.
There was a specialization for `(while (not= nil _) ...)` that
was incorrect when the while loop regresses to a thunk.

This will allow the creation of infinte

51678c1aba Extend power of the each form
This changes the implementation of the `next` function which
is now used to implement each. This let's us iterate over
more types, not just tables and structs.

23c7c3bf1c Allow disabling keyed hash function (prf) in conf
In some cases, one might want to disable what is currently
SipHash for speed / better security mechansims. For example, using
red black trees for caches rather than hash tables.

ea02b2fde9 Use siphash for string hashing.
The hash key still needs to randomly initialized
for the security advantage, but this patch is a
step closer to avoiding hash based DOS.

Further work may including exposing the raw hash
function for use by abstract types who also choose to
implement hash.

bc2bac8cd3 Fix memory issue in allocating decode buffer.
Since the decode table is currently a single table
per thread, we just make it a thread local to avoid
issues.

2df8660f8b Avoid buffer overrun
On very long binding names > 256 characters, a buffer overrun would be
trigger in janet_cfuns. Not a huge issue, since this is not really code
that would ever be user facing, but we can fix this.

3d40c95e80 Add ability to Janet signal from C functions.
While C functions are not re-entrant, signaling from a C function
can be used to implement async returns. When resuming a fiber that
signalled from within a C function, the fiber is started after the
instruction that emitted the signal. The resume argument is used
as the return result from the c function.
