LibreOffice uses its low-level API to look up files inside the app
bundle thousands of times, all the time, and especially when starting
something. Both when the process starts, and when a specific aspects
of the application starts (like after typing a first character into a
Writer document in a session). Having all those, too, go through this
alias (bookmark) resolve dance is just insane. There won't be any
aliases (bookmarks) there.

This shaves almost a second from the delay after typing the first
character into a Writer document in a session. There is still a
noticeable delay left, though, likely mostly caused by Python
(Lightproof) initialisation slowness. (It's cross-platform.)

I would say that it is a bit questionable whether the
macxp_resolveAlias() functionality is worth it at all, even.
