Allow a dissector to register preferences that it no longer supports as
obsolete; we silently ignore attempts to set those in a preferences file, so that we don't spam the user with error messages caused by them having saved preferences in an earlier release that contained those preferences. Make the Diameter and iSCSI dissectors register obsolete preferences. Crash if some code tries to register a preferences module with a name that contains something other than lower-case ASCII letters, numbers, or underscores, or that has already been registered, or if some code tries to register a preference with a name that contains something other than lower-case ASCII letters, numbers, underscores, or periods, or that has already been registered, so that we don't put code like that in a release and have to shovel code into "prefs.c" to fix it up later. (The problem with multiple modules or preferences with the same name should be obvious; the problem with names with blanks, or upper-case letters, or punctuation, is that they're a pain to type on the command line.) svn path=/trunk/; revision=4148
