* Rewrite FdEntry reusing as much libstd as possible
* Use the new FdEntry, FdObject, Descriptor struct in *nix impl
* Adapt Windows impl
* Remove unnecessary check in fd_read
Check `host_nread == 0` caused premature FdEntry closure and removal
which ultimately was resulting in an attempt at "double closing" of
the same file descriptor at the end of the Wasm program:
...
fd_close(fd=4)
-> errno=WASI_ESUCCESS
fd_close(fd=4)
-> errno=WASI_EBADF

* Add fd_p{read, write} tests
* Handle errors instead of panicking in path_get
* Use File::set_len to impl fd_allocate
* Add test for fd_allocate
* Replace all panics with Results
* Document the point of RawString

* Apply Alex's fix of using ManuallyDrop instead forget
* Clean up
* Explicitly specify workspace to avoid comp errors at tests
Now, test binaries are bundled with the repo, and
just like in CraneStation/wasmtime, the test cases
are generated automatically using build.rs. So all
it takes is to drop a new test binary in the
testsuite dir to get the test case for it generated
(with some caveats to do with handling preopens).
Linux's open returns ENOTDIR when used with O_DIRECTORY|O_NOFOLLOW and
the path is a symlink. Update the code to expect this.
FreeBSD's open returns EMLINK instead of ELOOP when using O_NOFOLLOW on
symlink. Update the code to expect this.
WASI currently lacks the ability to specify the full UNIX access control
information when creating files and directories, so for now just avoid
creating executable files and rely on the umask.
If a path_open call is requesting __WASI_RIGHT_FD_FILESTAT_SET_SIZE,
interpret that as a request for write privleges. If it is requesting
O_TRUNC, require __WASI_RIGHT_PATH_FILESTAT_SET_SIZE, since this is
a path operation rather than a FD operation.
Make `dec_slice_of` return a slice rather than a pointer-length pair,
freeing its users from having to call the unsafe `slice::from_raw_parts`.
This requires splitting `dec_slice_of` and `dec_ptr` into mut and
non-mut versions, and reorganizing poll_oneoff a little to avoid
borrow-checker errors -- decoded slices do alias the main memory, so
make sure functions only need one or the other.
