[Streams API] Split ReadableStream/Reader implementation according source type (JS vs native)

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[youenn fablet]

It may be cleaner to wrap all JS source specific handling (errors in particular) in separate classes from the core ReadableStream/ReadableStreamReader classes.

Fixed memory leak

I am quite surprised you specialize the reader, I was expecting a subclass only for ReadableStream.

I guess ReadableJSStream and ReadableJSStreamReader will grow right? I would give them their own header.

r=me in any case, no problem with this patch.

Useless blank line here.

ReadableJSStreamReader sole purpose is to store JS errors as a JSC::Strong. 
ReadableStream does also the chunk queue management.

Yes, maybe we could move ReadableJSStream and ReadableJSStreamReader to a different file. I would keep both classes together, ReadableJSStreamReader taking only 15 lines with the error storage code.
