## Message

```
std: add SbrkAllocator and use it for Plan 9

Implements issue #6451.
This was needed to support allocation on Plan 9 and now other operating
systems like DOS can also use it.

It is a modified version of the WasmAllocator since wasm also uses a
sbrk-esque allocation system.

This commit also adds the necessary system bits for sbrk to work on plan 9.

```
