333ae7c4f8 Make amalgamtion the default when building. 
This way we can support fewer build configurations. Also, remove
all undefined behavior due to use of memcpy with NULL pointers. GCC
was exploiting this to remove NULL checks in some builds.

28d41039b8 Add mod function to core. 
The `mod` function is a pair function with `%`, or te remainder
function and is distinct from it. This is taken from common lisp.

4fe005e3c3 Add righthand operator overloading. 
This is like python. Now, we just need to readd fuzzy
comparisons to have what python needs. Overloading
math functions would be neat, too.

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

It is easier to use constructs like defer

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.

51678c1aba Extend power of the each form 
This changes the implementation of the `next` function which

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.

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.

Try to clarify documentation and teach users the correct
way to read the 'in' so it is less likely to be confused
with python's usage of the keyword.

a3fb2d6e0a Add an optional finalizer to scratch resources. 
A finalizer can be attached to scratch allocations efficiently at any point in
it's lifecycle via janet_sfinalizer. Care was taken to keep allocations aligned
with  platform alignment requirements.

A big drawbacks to this approach is the waste of up to 16 bytes per scratch
allocation in the case the scratch memory does not require a finalizer.

aee1687215 Add RNG functionality to the math/ module. 
The new RNG wraps up state for random number generation, so
one can have many rngs and even marshal and unmarshal them.
Adds math/rng, math/rng-uniform, and math/rng-int.

Also introduce `in` and change semantics for
indexing out of range. This commit enforces stricter
invariants on keys when indexing via a function call
on the data structure, or the new `in` function.

The `get` function is now more lax about keys, and will
not throw an error when a bad key is used for a data structure, instead
returning the default value.

45c2819068 Improve flychecking. 
Flychecking will now work correctly with arity checking, and
will better handle imports. Well structured modules should interact
cleanly with the flychecker in a mostly safe manner, but maliciously
crafted modules can execute arbitrary code. As such, the flychecker is
not a good way to validate completely untrusted modules.

We also extend run-context with an :evaluator option to replace
:compile-only. This is more flexible and allows users to create their
own flychecker like functionality.

8dd8af742a Add eprintf and make printf a C function. 
This allows some more optimizations when printing to

more consistent with print and prin (Same with eprintf).

Calvin Rose
d47804d222 Add prin, eprint, and eprin functions. 
The print family of functions now writes output
to an optional buffer instead of a file bound to :out.

7910a5feef Add compile time arity checking. 
This should help catch a number of errors, but it
is a very shallow implementation of type checking. It will
catch some common misuses of functions at compile time
rather than runtime.

b26a7bb22a Disallow the empty string for some string fns. 
This will prevent these functions from being run
with empty strings, which usually produces useless
output, as the internal string search algorithm will
never "find" empty strings. This is by design, as it is
not always obvious which empty strings should be found in
the search text.

a8afc5b81f Sourcemapping uses line, column instead of offsets. 
This should be friendlier to most users. It does, however, mean
we lose range information. However, range information could be
recovered by re-parsing, as janet's grammar is simple enough to do this.

39f1d81fd4 Use :length method for (length abstract) 
Also adds the janet_lengthv API call. This is
needed because janet_length returns a 32 bit integer, where
as lengthv lets us return larger values (useful for typed arrays).

janet_mcall is an api function that should make it easier to call
a janet method from C code. It shares a similar signature with
janet_call.

98eaadf2d1 Simplify peg caching further. 
Remove the multiple caching tables we were using
and use the grammar table for caching. This works
well because we can use raw_get for checking the local cache, and normal
get fro checking the global cache.

54a04b5894 Fix some more recursion issues with pegs. 
A keyword reference only counts as visited if we have
it as cached in the memoized->table, and we know it was
originally referenced from the same grammar table. If these
two conditions are true, then compilation must work correctly.

Also add janet_table_get_ex.

711fe64a51 Add backmatch operator to pegs. 
(backmatch [tag?]) is similar to a back reference in regular expressions
(NOT to backwards capture in a peg). It only matches a pattern if
it exactly matches the text of the last capture. It does not consume
or push any captures to the capture stack.

b18f1e8127 Keep count fo allocated memory via malloc. 
We normally only track memory allocated with janet_gcalloc, but

run a collection if needed.
