jgruber b32ee40de8 [debug-wrapper] Conditional breaks, locals, evaluate, scopes
This CL adds support for:
* conditional breaks in setBreakpoint,
* locals in frame.local{Count,Name,Value},
* evaluation on a frame in frame.evaluate,
* and more detailed scope information in scopeObject.

Uses of several functions that are not covered by the
inspector protocol and are only used in tests have been removed.

Local handling has been modified to also include arguments as locals.
Inspector differs in this regard from our FrameDetails in that
arguments are always shown as locals. Argument-related functions
were removed.
