77bb0ebe3f Add limits to format to discourage huge prints. 
This should make system crashing prints happen less often in repl.

174ff87946 Change printing of abstracts with tostring in pp

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.

6c7f376410 Try to remove potential overflow bugs. 
Also make integer to size_t casts explicit rather than relying on
int32_t * sizeof(x) = size_t. This is kind of a personal preference for
this problem.

022be217a2 Remove ==, not==, and order[<,<=,>,>=]. 
This unifies equality and comparison checking. Before, we had
separate functions and vm opcodes for comparing general values vs.
for comparing numbers, where the numberic functions were polymorphic and
had special cases for handling NaNs. By unfiying them, abstract types
can now better integrate with other number types and behave as keys.

For now, the old functions are aliased but will eventually be removed.

66d82c4513 Add mailbox capacity for back pressure. 
(thread/send thread msg &opt timeout) can now timeout. Also
changed thread/self to thread/current for better consistency with

second. I think its bad to make things block forerver by default.

49954c7a30 Remove top-level unquote for comptime macro 
True top level unquote currently requires basically double compilation
