logging: ensure LogEntry.HttpRequest.RequestUrl has proper UTF-8

Adds a helper function "fixUTF8" whose purpose is to replace
invalid UTF-8 runes with the Unicode replacement character U+FFFD.

This ensures that LogEntry.HttpRequest.RequestUrl will
not choke while being proto marshalled.

This CL is probably one of many for which we shall use fixUTF8 to
ensure "invalid UTF-8" errors aren't produced while proto marshalling
payloads.

Fixes #1383
