Make sure that it is safe to call the callback for `_write()`
even in the presence of `.destroy()` calls during that write.
In particular, letting the write queue continue processing would
previously have thrown an exception, because processing writes
after calling `.destroy()` is forbidden.
One test had to be modified to account for the fact that callbacks
for writes will now always be called, even when the stream
is destroyed during the process.

This improves error handling for streams in a few ways.
1. It ensures that no user defined methods (_read, _write, ...) are run
after .destroy has been called.
2. It introduces an explicit error to tell the user if they are write to
write, etc to the stream after it has been destroyed.
3. It makes streams always emit close as the last thing after they have
been destroyed
4. Changes the default _destroy to not gracefully end streams.
It also updates net, http2, zlib and fs to the new error handling.

This adds computed properties to readable and writable streams to
allow access to the readable buffer, the writable buffer, and flow
state without accessing the readable or writable state.
These are the only uses of readable and writable state in the docs
so adding these work arounds allows them to be removed from the docs.
This also updates net, http_client and http_server to use the new
methods instead of manipulating readable and writable state directly.

`validChunk` allowed `undefined` as a chunk in object mode; however,
this was redundant, since:
- `validChunk()` is only used by `.write()`
- If the `validChunk()` check passes for `undefined`, `.write()`
calls `writeOrBuffer()`
- If `writeOrBuffer()` does not receive a Buffer, it calls
`decodeChunk()`
- `decodeChunk()` ignores `undefined` because it checks
`typeof chunk === 'string'`
- After that call, `chunk.length` is accessed, which throws an
error if `chunk` is undefined`.
This “fixes” a bug in the sense that `state.pendingcb` is no longer
incremented for write attempts that fail like this.
