Switch C files to CC files (#309)

Mostly this involves adding additional casts. Though there are a few
more substantial changes:

* The default method for relocating parser stacks no longer works
  because Bison assumes that C++ values can't be memcpy'd. Ours can, but
  there's no easy way to make the generated code do the right thing, so
  we do it manually
* Removed all uses of WabtBool and replaced with bool
* Renamed all uses of export and mutable -> export_ and mutable_
* Casting an invalid value to an enum triggers ubsan, so we have to be a
  little more careful about when we do it (see binary-reader.c:read_sections())
* It's illegal to forward-declare enums, so we just #include instead.
* Designated initializers are not allowed in g++, so we have to switch
  them to lazily initialized structures instead. Pretty horrible, so it
  will be nice to have a better solution for C++.
