`debuglog()` depends on `process.pid` and `process.env.NODE_DEBUG`,
so it needs to be called lazily in top scopes of internal modules
that may be loaded before these run time states are allowed to
be accessed. This patch makes its implementation lazy by default,
the process states are only accessed when the returned debug
function is called for the first time.

`readable.resume()` calls `.read(0)`, which in turn previously set
`needReadable = true`, and so a subsequent `.read()` call would
call `_read()` even though enough data was already available.
This can lead to elevated memory usage, because calling `_read()`
when enough data is in the readable buffer means that backpressure
is not being honoured.

This encapsulates the Node.js errors more by adding extra properties
to an error inside of the function to create the error message instead
of adding the properties at the call site. That simplifies the usage
of our errors and makes sure the expected properties are always set.

This patch splits the implementation of util.debuglog into a
separate file and explicitly initialize it during pre-execution
since the initialization depends on environment variables.
Also delays the call to `debuglog` in modules that are loaded during
bootstrap to make sure we only access the environment variable
during pre-execution.

If a readable stream was set up with `highWaterMark 0`, the while-loop
in `maybeReadMore_` function would never execute.
The while loop now has an extra or-condition for the case where the
stream is flowing and there are no items. The or-condition is adapted
from the emit-condition of the `addChunk` function.
The `addChunk` also contains a check for `state.sync`. However that part
of the check was omitted here because the `maybeReadMore_` is executed
using `process.nextTick`. `state.sync` is set and then unset within the
`read()` function so it should never be in effect in `maybeReadMore_`.

Currently, the debug statement in emitReadable is `emit readable` which
can be interpreted as the readable event is going to be emitted. But
I think the intent of this debug statment is just that the
emitReadable_ function was entered. If that was not the intent then
perhaps the debug statment should be moved into the if statement below
it.

Avoid trying to emit 'readable' due to the fact that
state.length is always >= state.highWaterMark if highWaterMark is 0.
Therefore upon .read(0) call (through .on('readable')) stream assumed
that it has enough data to emit 'readable' even though
state.length === 0 instead of issuing _read(). Which led to the TTY
not recognizing that someone is waiting for the input.

In Streams3 the 'readable' event/.read() method had a lower precedence
than the `'data'` event that made them impossible to use them together.
This make `.resume()` a no-op if there is a listener for the
`'readable'` event, making the stream non-flowing if there is a
`'data'` listener.

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.
