This patch adjusts nsSimpleURI to be stored as a single `mSpec` member, with cached indices of the various separators alongside. This improves the performance of calling `GetSpec()` on these URIs, as the caller will be able to share the underlying string buffer. This moves nsSimpleURI's implementation to be a bit more in-line with nsStandardURL, hopefully reducing performance surprises, especially around large data URIs. nsDataChannel is updated for the new perf characteristics in part 4.
