Pointer Reform: proper slicing and indexing (#1053)
* enable slicing for single-item ptr to arrays
 * disable slicing for other single-item pointers
 * enable indexing for single-item ptr to arrays
 * disable indexing for other single-item pointers

see #770
closes #386

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 d8ba1bc120 Improve fmt float-printing
- Fix errors printing very small numbers
 - Add explicit scientific output mode
 - Add rounding based on a specific precision for both decimal/exp
 modes.
 - Test and confirm exp/decimal against libc for all f32 values. Various
 changes to better match libc.

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.
