dwitte%stanford.edu ee64b32c3e Bug 209475: Make nsIPermissionManager more flexible for extensions.
Changes nsIPermissionManager.idl to accept type strings rather than integers; this allows consumers to register unique types more easily, without fear of conflicting with an already-existing one.

Also fixes some bounds-checking fu (sr=bz on irc for those additional portions).

patch by mvl; r=dwitte, sr=bz.
