Eric Rahm 07c97a5afe Bug 1423773 - Part 1: Remove usage of nsStringGlue.h. r=glandium
This removes an unnecessary level of indirection by replacing all
nsStringGlue.h instances with just nsString.h.

* Factory method to get an nsInputStream from a byte buffer. Result will
* implement nsIStringInputStream and nsISeekableStream.
*
* If aAssignment is NS_ASSIGNMENT_COPY, then the resulting stream holds a copy
* of the given buffer (aStringToRead), and the caller is free to discard
* aStringToRead after this function returns.
*
* If aAssignment is NS_ASSIGNMENT_DEPEND, then the resulting stream refers
* directly to the given buffer (aStringToRead), so the caller must ensure that
* the buffer remains valid for the lifetime of the stream object. Use with
* care!!
*
* If aAssignment is NS_ASSIGNMENT_ADOPT, then the resulting stream refers
* directly to the given buffer (aStringToRead) and will free aStringToRead
* once the stream is closed.
*
* If aLength is less than zero, then the length of aStringToRead will be
* determined by scanning the buffer for the first null byte.
