XML_Parser were never freed. While at it, move the parser initialization to
right before it is needed.

Run diff_tree_release_paths in the appropriate places, and add a test to
avoid NULL dereference. Better safe than sorry.

There are a few more occurrences of diff_tree_setup_paths for which I don't
know the code enough to correctly place the corresponding
diff_tree_release_paths. Interesting the function existed but was never
actually used ;)

This one is the same, but against pu, where Junio fixed my strbuf patch in
a different way than I did.

To be very honest, I wish the strbuf patch (that has potentially larger
impact) did not take these obviously correct leakfix patches hostage.
Will have to take a look but slowly (I'm at work now).
