Bug 1377978 - Make nsRange use uint32_t to offset r=smaug

DOM Standard defines that offset of Range is unsigned long.  However, nsRange uses int32_t to them.

This patch makes nsRange use uint32_t instead.  However, this patch does NOT allow to set over INT32_MAX as offset values since a lot of users of nsRange cannot treat the values as over INT32_MAX because a lot of internal APIs take int32_t as offsets.

For easier to search such points, this patch adds static_cast<int32_t> to uint32_t variables when they are used for int32_t arguments.

And note that nsContentUtils::ComparePoints() behaves odd.  It accepts negative offset and compares such value with valid offset simply.  This patch still uses int32_t offset variables in nsRange::CompareNodeToRange() even though it may be negative value if nsINode::IndexOf() returns -1 because the caller of it depends on this behavior.
