3372e47e5a Fix fd_fdstat_set_rights to set the rights. 
After checking that no new rights are being added, actually set the
rights, which may be a subset of the original rights.

c5bda1f4e1 Fix symlink resolution on Linux and FreeBSD. 
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.

9823bf6196 Change path_open to not create files with execute privleges. 
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.

32da43f600 Handle set-size rights correctly when truncating a file. 
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.

d20d787bb7 Don't grant __WASI_RIGHT_FD_FILESTAT_SET_SIZE for directories. 
RIGHTS_DIRECTORY_BASE should not include
__WASI_RIGHT_FD_FILESTAT_SET_SIZE, because that would imply the ability
to set the size of a directory.

eb1cf8b0a1 Make users of dec_slice_of safe. 
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.
