Upstream the changes from Bug 1165272 - unify Get*CodebasePrincipal with createCodebasePrincipal in nsIScriptSecurityManager

Browse Source 
One of the patches in https://bugzilla.mozilla.org/show_bug.cgi?id=1165272, specifically https://hg.mozilla.org/mozilla-central/rev/5a29e8bc51ca, touches PDF.js code. Unfortunately it was landed upstream without, as far as I can tell, notifying us about it.
This patch uplifts the relevant changes, and also adds preprocessor tags to avoid including unnecessary code in mozilla-central.
