I'd like to show a progress bar on initial download on the block chain, or when the client was disconnected for a while and needs to catch up.

This would give the user a more useful indication than just a raw count.

There is nBestHeight (which can be queried with getblockcount/getblocknumber), and the IsInitialBlockDownload function, but those only take into account the downloaded blocks. Is there a way to find out how many blocks there are in total? (without querying a third party)

I routinely ignore posters with paid advertising in their sigs.  You should too.

The version messages exchanged between peers right after connecting contains the current block height. You could take the median of your peers' heights as a low-reliability number.

Thanks. Low-reliability is not an issue, as it is an indication for visual purposes.
