Remove mentions of ENOSYS added in d97e44784bb5

aio(4) is a hard requirement in the kernel as of f3215338ef82. The
scenario that the patch was submitted for is no longer possible.

This isn't a straight up revert since the previous change also addressed
some minor issues.

aio_*(2): mention ENOSYS under ERRORS

ENOSYS can occur if aio(4) is not loaded in the kernel. Document this
behavior so consumers on FreeBSD can better understand that this is a
possible scenario.

aio_*(2): mention ENOSYS under ERRORS

ENOSYS can occur if aio(4) is not loaded in the kernel. Document this
behavior so consumers on FreeBSD can better understand that this is a
possible scenario.

Clean up the manpages slightly while here:
- Sort `ERRORS` by errno(3).
- Use `.Fx` instead of `FreeBSD`.

Add aio_writev and aio_readv

POSIX AIO is great, but it lacks vectored I/O functions. This commit
fixes that shortcoming by adding aio_writev and aio_readv. They aren't
part of the standard, but they're an obvious extension. They work just
like their synchronous equivalents pwritev and preadv.

It isn't yet possible to use vectored aiocbs with lio_listio, but that
could be added in the future.
