1596511175 Fix undefined behavior bug with errors. 
janet_vm_return_reg should only be set when janet_continue
is called. Otherwise, a panic may dump it's error message in
the wrong place, resulting in undefined behavior (often showing
the last return value or worse, segfaulting).

e5a56174e2 Switch fexists to use os/stat when available. 
When os/stat is not available, we first
try to read one byte from the file before
saying it is good. If that fails, it is not
a file that we can read from so it counts as not found.

ed65d04b81 Fix peg bug with arguments. 
By holding on a reference to argv for a long time, we
may trigger a use after free bug if the stack is resized. In
janet c function, argv is only vvalid up until the next stack operation
on the fiber. We could say that this is the dynamic lifetime of
argv.

To fix this, we copy extra arguments into a tuple, which is properly
garbage collected.

fa1c5c85b5 Remove no-capture mode in pegs. 
Some peg grammars could not capture values based on their position in a
larger grammar. This is a design limitation inheritted from LPeg, but no
longer needed as the replace mode is superseded by the accumulator mode,
which is more general if slightly harder to use.

b15cf193a0 Update os/stat 
os/stat can now take a keyword as the second argument
to avoid creating a table if one only wants on value

c5090606a4 Add os/stat function. 
Allows getting more information about files. This
is really useful for writing software that needs to inspect
the file system (like a static site generator). We still need
a way to iterate directories though.

color codes, which are widely supported. The codes
can also be turned off via the -m flag.

This simplifies the build machinery a bit.
core.janet is never actually included in the final

cb2caecbb3 Add janetconf.h for configuring builds. 
Rather than edit the Makefile or the janet.h header yourself, use
janetconf.h to configure builds. This has the benefit of making it
easier to configure janet in a persitent but easy way.
