How does one go about concatenating several H.264 raw streams into one without reencoding or quality loss?
The streams lacked any advanced features and represented contuous recording. There is no random seek/random access feature, either.

I found the following way, when trying to concatenate videostreams from the dashcam. Note: the streams had no random seek/random access
On Windows, perform the following,
copy /b file1.264 + file2.264 + file3.264 result.264
The command would byte-merge the raw streams, which works out well. If no random seek/random access feature existed, then it won't appear; but upon the uploading to YouTube, the random seek/random access feature was re-added.
