86e12369b6 Add alias for PEG repeat. 
A tuple where the first element is an integer is
a shortand for this.

6d096551f0 Add Peg combinators 'to' and 'thru'. 
Inpsired by the REBOL operators of the same name, these
combinators match bytes up to or inculding a given pattern.
(to patt) is (almost) equalivalent to (any (if-not patt 1)), and
(thru patt) is equivalent to (* (to patt) patt). The one difference
is that if the end of the input is reached and patt is not
matched, the entire pattern does not match.

7a84fc4742 Fix infinite loop in some cases. 
Problem - reusing a tainted variable without reinitializing.

8b5bcaee3c Add lenprefix combinator to pegs. 
This lets peg match n repeitions of a pattern, where
n is supplied from other parsed input and is not a constant.

b75a22b753 Make JANET_FRAME_SIZE consistent across architectures. 
This means unmarshalling fibers should work across arches.

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.

c3c42ef56f Fix case for #336. 
Also consider ascii 127 (delete) non-printable for string escapes.

5bbd507858 Address #336 case 3 
Fix error condition for bad abstract types - don't return NULL, panic.

b145d47863 Address cases 1 and 2 of #336. 
Mainly related to not checking ints < 0.

65379741f7 Address edge case of reduce2 when ind is empty. 
Same for accumulate 2.

3eb0927a2b Add accumulate(2) and reduce2 
These functions are variations on reduce and can be quite useful.
Improve error message for jpm as well.

b0d8369534 Increase reference accuracy of on-stack close envs. 
Using a bitset to indicate which stack values are upvalues, we
can more accurately track when a reference to a stack value
persists after the stack frame exits.

6123c41f13 Harden semantics for and and or macros. 
There was perviously a bit of fuzziness on returning false/nil
from these macros that has been removed.

734c85d7ef Properly handle recursion with labels. 
Use an empty buffer, which has pointer equality semantics, for
tag from a label.

59d288c429 Add prompt and return. 
User friendly delimited continuations. While this was doable with
signals before, this does not require C and will play nicely with
existing error handling, defers, and with statements.
