J. Ryan Stinnett 5bede71f0d Bug 1238160 - Rename nsILoadContext::GetIsInBrowserElement. r=smaug,mayhemer
This change renames nsILoadContext::GetIsInBrowserElement to
GetIsInIsolatedMozBrowserElement.  Other methods that pass these values around
also have name changes.

Tokens such as "isInBrowserElement" have previously been serialized into cache
keys, used as DB column names, stored in app registries, etc.  No changes are
made to any serialization formats.  Only runtime method and variable names are
updated.

No behavior changes are made in this patch, so some renamed methods may have
nonsensical implementations.  These are corrected in subsequent patches
focused on behavior.
