If the resulting buffer.toString() call in fs.read throws, catch the
error and pass it back in the callback.
This issue only presents itself when fs.read is called using the legacy
string interface:
fs.read(fd, length, position, encoding, callback)

These changes affect the following functions and their synchronous
counterparts:
* fs.readFile()
* fs.writeFile()
* fs.appendFile()
If the first parameter is a uint32, it is treated as a file descriptor.
In all other cases, the original implementation is used to ensure
backwards compatibility. File descriptor ownership is never taken from
the user.
The documentation was adjusted to reflect these API changes. A note was
added to make the user aware of file descriptor ownership and the
conditions under which a file descriptor can be used by each of these
functions.
Tests were extended to test for file descriptor parameters under the
conditions noted in the relevant documentation.

When the listener was truthy but NOT a function, fs.watchFile would
throw an error through the EventEmitter. This caused a problem because
it would only be thrown after the listener was started, which left the
listener on.
There should be no backwards compatability issues because the error was
always thrown, just in a different manner.
Also adds tests for this and other basic functionality.

1. writeFileSync bumps position incorrectly, causing it to drift in
iteration three and onwards.
2. Append mode files will get corrupted in the middle if writeFile or
writeFileSync iterates multiple times, unless running on Linux. position
starts out as null so first write is OK, but then position will refer to
a location inside an existing file, corrupting that data. Linux ignores
position for append mode files so it doesn't happen there.
This commit fixes these two related issues by bumping position correctly
and by always using null as the position argument to write/writeSync for
append mode files.
