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.
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.
This should help address #81. Also hide janet_exit
and janet_assert, as they are really meant for internal usage.
I have not verified that this yet actually works with Rust's
bindgen.
Leave in issues with calling memcpy with size=0. If these
become a problem, will probably add a janet_memcpy as memcpy
is used so much in the code without 0 checks.
If a comment is not followed by a newline character, then
we got a false parse error. This is because the comment
state is left on the parse stack when we finished parsing, and
since the parse stack was not emtpy, we assumed an error.
This commit adds the parser/eof function, which lets the parser know
that an eof was reached. Before, we simply added a fake newline
character in some cases, and in the case of reading a file, we did
nothing, hence the bug.
A consistent style should help with contributors and
readability. We use astyle as the formatter as can make a pretty
good approximation of the current style and my preferred style.

We need to be able to detect tuple type from janet code, otherwise
tuples will contain hidden state. The tuple/type function is able
to detect the flags in the tuple so the programmer can access them
if needed.
This should speed up start time and reduce malloc/free
usage to about 15% of what is what previously for startup.
The current cost is slightly larger binary as the representaion
of the image is currently less compact than source code.
Error handling is implemented with setjmp/longjmp so code
can be more concise. This required a very large but straight forward refactor for all
of the libraries.
