This is part of a closed captioning system for digital cinema. I get a
Resource Presentation List from the cinema server. It's an XML file that
includes the URLs for each of the caption files (typically one for each
reel and language). These URLs are typically absolute, but may be relative
to the URL of the RPL. So, I need a function where I can pass in my new
URL, a base URL, and get back an absolute representation of the new URL.
So, I think I need to be able to handle relative URLs that include such
things as

./file
../file
../../path/path/file
/path/file

etc.

I'm then passing the absolute URL to an http client I wrote that uses the
Microchip TCP/IP stack to go get the required files.

Thanks for the comments so far!
