New Zig formal grammar (#1685)
Reverted #1628 and changed the grammar+parser of the language to not allow certain expr where types are expected

Solve the return type ambiguity (#1628)
Changed container and initializer syntax
* <container> { ... } -> <container> . { ... }
* <exrp> { ... } -> <expr> . { ...}

remove `this`. add `@This()`.
closes #1283

Marc Tiehuis a7527389cc Make poly1305 and x25519 more idiomatic zig
This also adjusts the current hash/hmac functions to have a consistent
interface allowing easier switching/testing.

Andrew Kelley 7912061226 remove integer and float casting syntax
* add `@intCast`
 * add `@floatCast`
 * add `@floatToInt`
 * add `@intToFloat`

See #1061

Andrew Kelley fcbb7426fa use * for pointer type instead of &
See #770

To help automatically translate code, see the
zig-fmt-pointer-reform-2 branch.

This will convert all & into *. Due to the syntax
ambiguity (which is why we are making this change),
even address-of & will turn into *, so you'll have
to manually fix thes instances. You will be guaranteed
to get compile errors for them - expected 'type', found 'foo'

Marc Tiehuis f68c2e0a14 Fix off-by-one error in all crypto functions 2018-04-04 21:32:23 +12:00
Marc Tiehuis 7a893691c0 Unroll Sha3 inner loop
Issue #699 since fixed. Nearly a x3 perf improvement.

Using --release-fast.

Sha3_256 (before): 96 Mb/s
Sha3_256  (after): 267 Mb/s

Sha3_512 (before): 53 Mb/s
Sha3_512  (after): 142 Mb/s

No real gains from unrolling other initialization loops in crypto
functions so have been left as is.

Andrew Kelley 3671582c15 syntax: functions require return type. remove `->`
The purpose of this is:

 * Only one way to do things
 * Changing a function with void return type to return a possible
   error becomes a 1 character change, subtly encouraging
   people to use errors.

See #632

Here are some imperfect sed commands for performing this update:

remove arrow:

```
sed -i 's/\(\bfn\b.*\)-> /\1/g' $(find . -name "*.zig")
```

add void:

```
sed -i 's/\(\bfn\b.*\))\s*{/\1) void {/g' $(find ../ -name "*.zig")
```

Some cleanup may be necessary, but this should do the bulk of the work.

Andrew Kelley 793f031c4c remove 32-bit windows from supported targets list
we still want to support it, but there are too many bugs
to claim that we support it right now.
