Support multiple interrupt requests in v8 API.
...
There might be a number of clients that would like to
setup an interrupt request on the Isolate.
The patch also deprecates ClearInterrupt API. As long as
the interrupt handler is called outside of locks there's no way
to guarantee that the handler will not be called after
ClearInterrupt was invoked as it might have already started execution.

Script streaming: more UTF-8 handing fixes (again).
...
1) Since we fill the output buffer both from the chunks and the conversion
buffer, it's possible that we run out of space and call CopyCharsHelper with 0
length. The underlying functions don't handle it gracefully, so check there.
2) There was a bug where we used to try to copy too many characters from the
beginning of the data chunk into the conversion buffer. Continuation bytes in
UTF-8 are of the form 0b10XXXXXX. If a byte is bigger than that, it's the first
byte of a new UTF-8 character and we should ignore it.
These two together (or maybe in combination with surrogates) are a probable
reason for crbug.com/420932.
3) The test data was off; \uc481 is \xec\x92\x81.

Script streaming: UTF-8 handling fix.

The problem was that there can be several multi-byte UTF-8 characters near the
splitting point of the data chunks, and the code didn't handle it properly.
This was also the source of crbug.com/417891 - I thought the crash can only
happen when V8 is passed invalid UTF-8 data, but it can also happen in the
abovementioned case. After the fix, we handle the valid UTF-8 case and also
guard against invalid UTF-8 data.
