Stop caching jsdIValues, it doesn't seem to be worth the lookup cost. This has the side effect of plugging the leak, as described in the bug.
also...
* Convert a few raw pointers to nsCOMPtrs
* Fix a bug where removing the last filter did not null out the list head,
causing a crash the next time filters were used.
* Track live jsdStackFrames, so we can invalidate them all when execution
continues. Without this, only the top frame is properly invalidated, and any
other frame accessed after a continue will do Bad Things.
* Add some debugging prints to GetInitAtService, which seems to be failing at
random times.
implement the jsdIContext interface.
create only one jsdValue wrapper per unique jsval.
add executionContext property to jsdIStackFrame.
add enumerateContexts to jsdIDebuggerService.
add jsdIContextEnumerator interface.
adds jsdIDebugHook interface, change the meaning of jsdIErrorHook.
error hook is called when an error occurs, and is given information about the error report.
debug hook is called when/if the error hook returns false, and is given information about the ececution state.
large addition to the jsd_xpc component allows arbitrary filtering of debug hooks by url pattern, line range, and global object. also adds ability to begin instrumenting jsscripts at app startup.
move debug object counters and various constructors to jsd_xpc.cpp
add LiveEphemeral struct to reperesent a link in a PRCList of ephemeral objects.
declare jsdIEphemeral interface in objects that need it, add invalidaAll static method to jsdIProperty and jsdIValue. jsdIObject still needs work.
declare and initialize new provate members in jsdScript, copy important script properties at jsdScript creation time, so they're around after Invalidate().
add onForRuntime() method to jsdIDebuggerService to let native code turn on the deubgger (on() can only be called from js)
register an app-start observer so we can turn on the debugger at startup if "js.debugger.autostart" pref is true.
r=peterv, bug 81840
move from pc as a ulong to pc as an object wrapped around a uword
relocate jsdService constructor to jsd_xpp.cpp in order to initialize the global
service
