445b03384a introduce std.heap.ArenaAllocator and std.heap.DirectAllocator
* DirectAllocator does the underlying syscall for every allocation.
 * ArenaAllocator takes another allocator as an argument and
   allocates bytes up front, falling back to DirectAllocator with
   increasingly large allocation sizes, to avoid calling it too often.
   Then the entire arena can be freed at once.

The self hosted parser is updated to take advantage of ArenaAllocator
for the AST that it returns. This significantly reduces the complexity
of cleanup code.

docgen and build runner are updated to use the combination of
ArenaAllocator and DirectAllocator instead of IncrementingAllocator,
which is now deprecated in favor of FixedBufferAllocator combined
with DirectAllocator.

The C allocator calls aligned_alloc instead of malloc, in order to
respect the alignment parameter.

Added asserts in Allocator to ensure that implementors of the
interface return slices of the correct size.

Fixed a bug in Allocator when you call realloc to grow the allocation.

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.
