267271 - networking validity checking

Status: RESOLVED INCOMPLETE

I've talked w/ several of the mozilla staff on and off about writing a set of
functions in javascript that do validity checking.

I noticed this was a potential problem with the pacUtils that support PAC files,
potentially bad input could cause really strange results.

I think we've historically assumed that the URL's will alwasys be parsed into
sensible values, but it doesn't mean that they always would.

The general idea is that moving pacUtils out into it's own resource + some
validity functions would also be good for other areas of the product, like in
the prefs panels, etc.

I'm finishing off the first run of functions.

My thinking is this:

the functions will focus on validity checking, not fixup, so they will assume
that you have done any leading/trailing whitespace removal, cleanup, etc. 

In a web-based app, it might be desirable to call them with a check for a cookie
like "ipvalidation=off", so you can turn off all validity checking w/ a cookie
change, which is is easy to do via a javsacript: URL.
