Bug 67609 – Web Inspector: re-implement RawSourceCode.

• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

Web Inspector: re-implement RawSourceCode.

RawSourceCode content and source mapping loading logic is too complex, re-implement it using simpler semantics:
1) Initially, RawSourceCode doesn't have any content or mapping because content loading and
formatting operations are asynchronous, it only has scripts metadata. We don't update UI right
after RawSourceCode creation until full RawSourceCode representation is ready (content + mapping).
2) When RawSourceCode representation is ready (e.g. resource is finished, or content is formatted 
if in pretty-print mode) we dispatch SourceMappingUpdated event to notify the listeners that
source code should be shown to user and raw locations should be converted to ui locations
(to show breakpoins, messages, call frames etc in UI). At this moment, all source file's content
is ready for loading and source mapping is available.
3) Later, RawSourceCode representation may change again, e.g. if pretty-print mode is toggled, or
blocked resource is finished etc., in that case SourceMappingUpdated is dispatched again to update
source code, links and decorations in UI.
