040736caac Adds function names to host functions and improves logging listener (#697)
This improves the experimental logging listener to show parameter name
and values like so:

```
--> ._start.command_export()
        	--> .__wasm_call_ctors()
        		--> .__wasilibc_initialize_environ()
        			==> wasi_snapshot_preview1.environ_sizes_get(result.environc=1048572,result.environBufSize=1048568)
        			<== ESUCCESS
        		<-- ()
        		==> wasi_snapshot_preview1.fd_prestat_get(fd=3,result.prestat=1048568)
        		<== ESUCCESS
        		--> .dlmalloc(2)
        			--> .sbrk(0)
        			<-- (1114112)
        		<-- (1060080)
--snip--
```

The convention `==>` implies it was a host function call
(def.IsHostFunction). This also improves the lifecycle by creating
listeners during compile. Finally, this backfills param names for
assemblyscript and wasi.

14d892d310 Removes api.ImportRenamer for a different approach to "env" (#680)
Before, we introduced a type `api.ImportRenamer` to resolve conflicts
where the "env" module was shared between AssemblyScript and
user-defined functions. This API was never used in GitHub, and is
complicated.

AssemblyScript also isn't the only ABI to share the "env" module, as
other web APIs like Emscripten do also. The less complicated approach is
to have packages that need to share "env" use
`ModuleBuilder.ExportFunctions` instead, and use namespaces as needed if
there is overlap.

8c2f0928bc Panics caller on exit error (#673)
This changes the AssemblyScript abort handler and WASI proc_exit
implementation to panic the caller which eventually invoked close.

This ensures no code executes afterwards, For example, LLVM inserts
unreachable instructions after calls to exit.

See https://github.com/emscripten-core/emscripten/issues/12322

fe1cde140d Removes redundant error handling (#668)
This consolidates to use EBADF in places go uses it in syscalls to
reduce where we formally returned both bool and err. This also removes
the redundant panic type handling as go will already panic with a
similar message.

92ba4929e5 Drops support for the WebAssembly text format (#614)
This drops the text format (%.wat) and renames
InstantiateModuleFromCode to InstantiateModuleFromBinary as it is no
longer ambiguous.

We decided to stop supporting the text format as it isn't typically used
in production, yet costs a lot of work to develop. Given the resources
available and the increased work added with WebAssembly 2.0 and soon
WASI 2, we can't afford to spend the time on it.

The old parser is used only internally and will eventually be moved to
its own repository named watzero, possibly towards archival.

See #59

7fec94b2e1 experimental: consolidates context patterns (#579)
This consolidates the pattern used for context overrides, notably
replacing clock overrides via experimental.WithTimeNowUnixNano
and making all context keys internal.

This also makes sure experimental example tests are handled the same
way, notably backfilling one for WithFS
