Michael Müller 1ccb590d18 Better allocator for wasm (#1460)
* Add Arch Linux installation instructions

* Enable tracing heap size

* Extract heap

* Replace linear allocator with buddy allocator

* Fix test

The purose of this big block is for the tests
to test a failure when the block is too big
though. The improved buddy allocation strategy
results in this block fitting on the heap now.
Hence the increase.

* Get rid of memcpy in to_vec()

* fixup: Style and comments

* fixup: Split Linux instructions by distribution

To prevent misunderstandings of people executing both.

* fixup: Remove unnecessary types and code

* fixup: Make Pointers start from 1, remove some panics, code improvements

* fixup: Return 0 on errors

* fixup: Move loop to separate function

* fixup: Use FnvHashMap instead of HashMap

* fixup: Fix error handling

* fixup: Use current_size() instead of used_size()

* fixup: Fix and document allocation offset

* fixup: Remove unnecessary multiplication

* fixup: Fix comments

* fixup: Remove Arch installation instructions

* Revert "Fix test"

This reverts commit 292c177df8efaa4658293748a13b1ab1c0b76ea8.

* fixup: Remove unused code, improve import

* fixup: Proper alignment

* fixup: Do not use internal constant in public description

* fixup: Add comment regarding invariants

* fixup: Move assertion to compile-time check

//! This is entirely deprecated with the idea of a single-module Wasm module for state transition.
//! The dispatch table should be replaced with the specific functions needed:

//! - add_transaction(InProgressBlock) -> InProgressBlock
//! It is left as is for now as it might be removed before this is ever done.
