Changes that need to be addressed in uvwasi

Work is going on in the snapshot2 branch. Progress is indicated in the list below.

The __wasi_proc_raise() function and the __wasi_signal_t type and constants were removed in Remove proc_raise and the signal types and constants. WebAssembly/WASI#136. This change impacts ephemeral only.
The functions __wasi_path_permissions_set() and __wasi_fd_permissions_set() were added in Add functions for working with file permissions. WebAssembly/WASI#170.
The __wasi_poll_oneoff() function should return EINVAL if nsubscriptions is zero. Make poll return errno::inval if there are no subscriptions. WebAssembly/WASI#193.
The uvwasi_filetype_t added UVWASI_FILETYPE_FIFO in Add FIFO filetype to match POSIX WebAssembly/WASI#189.
The UVWASI_O_CREAT flag should be renamed to UVWASI_O_CREATE, in accordance with Rename creat to create. WebAssembly/WASI#199.
Union formats have changed in Change witx unions to be tagged WebAssembly/WASI#220. See Update to use witx tagged unions WebAssembly/wasi-libc#165.
The clocks process_cputime_id and thread_cputime_id were removed in Remove the cputime clocks. WebAssembly/WASI#197.
The error acces was renamed to access in Rename acces to access #209 WebAssembly/WASI#211.
The uvwasi_dirent_t fields have been rearranged to move the d_namlen field to the end of the struct. See Move $d_namlen to the end of $dirent WebAssembly/WASI#264.

This was changed as part of snapshot_preview2. Refs: #59

snapshot_preview2 added the constraint that poll_oneoff() should return EINVAL if nsubscriptions is zero. Even though poll_oneoff() isn't implemented yet, this commit adds the necessary input validation. Refs: #59

snapshot_preview2 dropped the signal related APIs. This means removing __wasi_proc_raise() and __wasi_signal_t, which is what this commit does. Refs: #59

snapshot_preview2 added support for FIFO types. Prior to this, FIFOs were treated as sockets and unknown files. Refs: #59

snapshot2 adds the following for working with file permissions: - A permissions data type representing read, write, execute, and "private" permissions. - path_filestat_set_permissions() which is similar to fchmodat(). - fd_filestat_set_permissions() which is similar to fchmod(). - Two new rights for calling the two new functions. - A permissions field added to the filestat type. - A permissions argument passed to path_open(). This will need to be verified against the wasi-libc once the changes land there. Based on the auto-generated WASI docs, it seems likely that existing constants will change/break. Refs: #59
