Bug 1425769: Base class for ShadowRoot and Document to manage style state. r=smaug This also removes some confusing comments around nsIDocument regarding some kind of "special" stylesheets, which don't seem to exist anymore, and consolidates StyleSheetList so that we only have one implementation. I think that fixes a potential leak on the shadow root code (even though the API is v0 only), given the pointer from the ShadowRootStyleSheetList to the ShadowRoot wasn't being CCd. Also, more stuff could be renamed, methods removed, etc, feel free to suggest more cleanup, I've done mostly the minimal. Next steps are moving the stylesets there and stop using the proto binding sheet list / resources. MozReview-Commit-ID: D9hnDgPQAS5

// there appear to be two types of STL container checking.  The
// former is enabled by -D_DEBUG (which is implied by -MDd or -MTd), and
// looks to be full generation/mutation checked iterators as done by
// _GLIBCXX_DEBUG.  The latter appears to just be bounds checking, and
// is enabled by the following macros.  It appears that the _DEBUG
// iterators subsume _SECURE_SCL, and the following settings are
// default anyway, so we'll just leave this commented out.
//#  define _SECURE_SCL 1
//#  define _SECURE_SCL_THROWS 0
#else
// Note: _SECURE_SCL iterators are on by default in opt builds.  We
// could leave them on, but since gcc doesn't, we might as well
// preserve that behavior for perf reasons.  nsTArray is in the same
// camp as gcc.  Can revisit later.
//
// FIXME/bug 551254: because we're not wrapping all the STL headers we
// use, undefining this here can cause some headers to be built with
// iterator checking and others not.  Turning this off until we have a
// better plan.
