This commit improves the SystemError messages by allowing user
to combine a custom message and the libuv error message. Also
since we now prefer use subclasses to construct the errors instead
of using `new errors.SystemError()` directly, this removes
the behavior of assigning a default error code `ERR_SYSTEM_ERROR`
to SystemError and requires the user to directly use the
`ERR_SYSTEM_ERROR` class to construct errors instead.
Also merges `makeNodeError` into the SystemError class definition
since that's the only place the function gets used and it seems
unnecessary to introduce another level of inheritance. SystemError
now directly inherits from Error instead of an intermmediate Error
class that inherits from Error.
Class hierarchy before this patch:
ERR_SOCKET_BUFFER_SIZE -> Error (use message formatted by SystemError)
ERR_SYSTEM_ERROR -> NodeError (temp) -> Error
After:
ERR_SOCKET_BUFFER_SIZE -> SystemError -> Error
ERR_TTY_INIT_FAILED -> SystemError -> Error
ERR_SYSTEM_ERROR -> SystemError -> Error
Error messages before this patch:
```
const dgram = require('dgram');
const socket = dgram.createSocket('udp4');
socket.setRecvBufferSize(8192);
// Error [ERR_SOCKET_BUFFER_SIZE]: Could not get or set buffer
// size: Error [ERR_SYSTEM_ERROR]: bad file descriptor:
// EBADF [uv_recv_buffer_size]
// at bufferSize (dgram.js:191:11)
// at Socket.setRecvBufferSize (dgram.js:689:3)
const tty = require('tty');
new tty.WriteStream(1 << 30);
// Error [ERR_SYSTEM_ERROR]: invalid argument: EINVAL [uv_tty_init]
// at new WriteStream (tty.js:84:11)
```
After:
```
const dgram = require('dgram');
const socket = dgram.createSocket('udp4');
socket.setRecvBufferSize(8192);
// SystemError [ERR_SOCKET_BUFFER_SIZE]: Could not get or set buffer
// size: uv_recv_buffer_size returned EBADF (bad file descriptor)
// at bufferSize (dgram.js:191:11)
// at Socket.setRecvBufferSize (dgram.js:689:3)
const tty = require('tty');
new tty.WriteStream(1 << 30);
// SystemError [ERR_TTY_INIT_FAILED]: TTY initialization failed:
// uv_tty_init returned EINVAL (invalid argument)
// at new WriteStream (tty.js:84:11)

Refactor the structure of the os module to use more efficient
module.exports = {} pattern.
Add Symbol.toPrimitive support to os methods that return simple
primitives. This is a minor tweak that makes using these slightly
more friendly when doing things like:
```js
var m = `${os.tmpdir}/foo`
```

Assigns a static identifier code to all runtime and documentation
only deprecations. The identifier code is included in the emitted
DeprecationWarning.
Also adds a deprecations.md to the API docs to provide a central
location where deprecation codes can be referenced and explained.

The require('constants') module is currently undocumented and mashes
together unrelated constants. This refactors the require('constants')
in favor of distinct os.constants, fs.constants, and crypto.constants
that are specific to the modules for which they are relevant. The
next step is to document those within the specific modules.

Changes included in this commit are
1. Making the deprecation messages consistent. The messages will be in
the following format
x is deprecated. Use y instead.
If there is no alternative for `x`, then the ` Use y instead.` part
will not be there in the message.
2. All the internal deprecation messages are printed with the prefix
`(node) `, except when the `--trace-deprecation` flag is set.

os.tmpdir() began stripping trailing slashes in
b57cc51d8d. This causes problems if
the temp directory is simply '/'. It also stripped trailing
slashes without first determining which slash type is used by
the current operating system. This commit only strips trailing
slashes if another character precedes the slash. On Windows, it
checks for ':', as not to strip slashes from something like 'C:\'.
It also only strips slashes that are appropriate for the user's
operating system.
