9985f787eb Add custom base option to number peg combinator. 
Allows parsing custom bases without needed Janet specific prefixes.

cccbdc164c Add (number combinator to peg). 
This allows using Janet's number parser without creating
intermediate strings.

a3e812b86d Fix #505 - bat int64 parsing. 
Fixes an off-by-1 error.

Also makes windows testing hopefully a bit less flaky.

c876e63010 Fix overflow in exponent estimation in strtod.c. 
Found by OSS-Fuzz.

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.

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.

9dd152dc28 Add features.h for feature test macros. 
Because we use an amalgated build, feature
test macros should be set in a single file that
is included before any other headers, and is placed
at the top of the amalgamated build.

688d297a18 Address Issue #184. 
Fix strtod.c with better range checking to prevent DOS.

805b3bbb88 Numbers require at least 1 significant digit. 
Address issue #96

f10028d41a Add function versions of macro API bindings. 
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.

bad040665f Renamed bigint -> inttypes / int 
A lot of refactoring larger integer types. Fix a number
of casting errors, but mostly rename things. Also try to
limit use of template-like macros as they bloat the binary
if not used in moderation. We were able to reduce the size of
typed array code as well by using a single view types.

a07d76b264 use custom string to bigint reader in place of strtol 
for better compatibility with default janet number reader

9d4effc02e Add make format to format code. 
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.

Astyle can be found at http://astyle.sourceforge.net/astyle.html

ed72dcf82d Rename the header <janet/janet.h> to <janet.h> 
Makes it easier to use and remember, and makes the
variable `module/*headerpath*` make more sense.

611543c48b Add source amalgamation 
The amalgamated source concatenates all sources
to a file janet.c which can be used for
embedding janet, much in the same way as sqlite
or mongoose.

5c84f0f5d9 Work on number code for more expected behavior and better rounding. 
Still needs work and testing.

6b95326d7c First commit removing the integer number type. This should 
remove some complexity and unexpected behavior around numbers in
general as all numbers are the same number type, IEEE 754 double
precision numbers. Also update examples and tests, some of which were
out of date.

Some more testing may be needed for new changes to numbers.

1e4f221170 Move strtod to core, and rename parse-number, parse-integer, and 
parse-real functions to scan-number, scan-integer, and scan-real.
Add very basic format function for formatting strings for printing.
