Patch by Arnaud Renevier <a.renevier@sisa.samsung.com> on 2013-01-25
Reviewed by Kenneth Russell.

Define webGLErrorsToConsoleEnabled as true by default. Also,
WebGLRenderingContext::m_synthesizedErrorsToConsole is true by default
and can be disabled by settings.

Add a ConsoleDisplayPreference parameter to synthesizeGLError
(defaults to DisplayInConsole). When called with DontDisplayInConsole,
an error message will not be displayed (even if
m_synthesizedErrorsToConsole is true).

Call synthesizeGLError with DontDisplayInConsole in case of synthetic
context lost.

No new tests: covered by existing tests.

LayoutTests:

Set WebGLErrorsToConsoleEnabled to false for WebGL tests which have
errors. Some WebGL error messages depend on OpenGL implementations, so
logging error messages would lead to platform specific output.
