Fix bug with large extension field numbers.
Previously, extensions with field numbers greater than 268435455 would
result in a compile time error in generated code that looks something
like this:
Foo.java:3178: error: integer number too large: 3346754610
3346754610);
This is because we were trying to represent the tag number (an
unsigned int) using a java int constant, but java int constants are
signed, and can't exceed Integer.MAX_VALUE.
Fixed by declaring it as a long instead, and casting it down to an
int in the implementation. This is safe, because the tag value always
fits in 32 bis.
