enabled.

LibWasm: Give traps a reason and display it when needed
...
This makes debugging wasm code a bit easier, as we now know what fails
instead of just "too bad, something went wrong".

LibWasm: Limit the call stack depth and the number of executed insts
...
These limits are described in the spec, and we're supposed to stop
execution at some point.
The limits are arbitrarily chosen.

LibWasm: Start implementing a basic WebAssembly binary format parser
...
This can currently parse a really simple module.
Note that it cannot parse the DataCount section, and it's still missing
almost all of the instructions.
This commit also adds a 'wasm' test utility that tries to parse a given
webassembly binary file.
It currently does nothing but exit when the parse fails, but it's a
start :^)
