register_tempfile(): new function to handle an existing temporary file
Allow an existing file to be registered with the tempfile-handling
infrastructure; in particular, arrange for it to be deleted on program
exit. This can be used if the temporary file has to be created in a
more complicated way than just open(). For example:
* If the file itself needs to be created via the lockfile API
* If it is not a regular file (e.g., a socket)
