Followup to #1851.

Do we really want to have this output checked in like this?
If so, we should probably automate its update ot at least add
a check to avoid it getting out-of-date.

Use stricter compiler settings and fix the resulting warnings.
This is precursor to landing windows compiler support for wasm2c.
See #1843.

This finishes #985. This
- replaces the old names in the tests with the new names
- drops support for the deprecated names
- renames test files to match new instruction names
I don't think dropping support for the old names will be a problem at
this point. #985 says the old names are supported for convenience but we
should remove those too at some point; that "some point" may have well
arrived given that three years have passed.
The lists of names updated are in #933, #1564, WebAssembly/spec#720.

We really should enable Werror on CI..

The previous change prevented `WASM_RT_MEMCHECK_SIGNAL_HANDLER_POSIX`
from being defined, but `WASM_RT_MEMCHECK_SIGNAL_HANDLER` was still
defined, which would prevent the memory bounds check.

* Test whether this works for macOS
* Use __builtin_memcpy (fixes bug on macOS)
* Use #if instead of #ifdef (so 0 and 1 values work properly)
* Add `WASM_RT_SETJMP` and `WASM_RT_LONGJMP` macros

This example demonstrates how to use imported functions. The `rot13`
program takes each command line argument, and rot13-encodes it.
The exported `rot13` function has no arguments, and instead calls back
into the program (via `fill_buf`) with a buffer to fill in. When the
function finishes it calls `buf_done`.
(rot13.wat is the same as in src/test-interp.cc.)

Also fix bug when parsing elem/data segment; the table/memory index is
stored as an LEB128, not a U8.

`update-spec-tests.py` now will update the tests in the
`test/wasm2c/spec` directory.

Fixes issue #868.

* Described how to use it, and put it near the top of the doc
* Added the sources and generated files
|
|
|
This makes it easier to use outside of running wasm2c spec tests.
