Bug 165975 – Address some style problems found by static analysis

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Brent Fulgham]

The static analyzer identified some miscellaneous problems in the code:

1. Some methods did not actually override the expected method due to signature differences.
2. Some large arguments were being passed by value.

This patch tidies up these issues.

Note that the instances of "const int*" -> "const int* const", etc., were to match the method declarations in the implementation files.

This change caused a warning on Windows.  Let's double check it.

As long as we're touching this, can we make this return a Ref?

I think this is due to out-of-sync intermediate files. It's clear that JavaScriptCore/inspector/agents/InspectorDebuggerAgent.cpp is declared as "const String* const" (etc.), so the headers should be made to match.

Someday these will use std::optional.

You'll need to rebaseline the expected test results:

./Tools/Scripts/run-inspector-generator-tests --reset-results
