Close-protecting OutputStream and InputStream wrappers

[GoogleCodeExporter]

I propose to add two methods "OutputStream closeProtect(OutputStream)" and 
"InputStream closeProtect(InputStream)" to the ByteStreams class. The methods 
would take the given stream and return a wrapper that simply forwards all 
method calls except for "close()", so that calling "close()" on the returned 
stream will have no effect.

Use cases for this are for example cases where you wrap a stream into another 
stream and want to close the wrapper stream, but not the wrapped stream. I have 
a concrete use case for this that is described in this StackOverflow question: 
http://stackoverflow.com/q/15907105/396730

The methods could of course also have different names, e.g., "preventClosingOf" 
or "uncloseableStream".

Apache Commons IO has CloseShieldOutputStream and CloseShieldInputStream that 
have the same effect, but I prefer Guava and would think this is a worthy 
addition.
