The new function md_random_seed() has replaced time() + getpid() and
similar methods. Putting everything in mdport.c slightly reduces the
warnings and workarounds.
Converting all function definitions to ANSI style accounts for most of
the change. This has exposed other problems, such as daemons not
actually being their stated type, that will require more careful
solutions.
The player name is stored in whoami[], which is length 80 in most games
(1024 in rogue5). Only the first 10 chars were used to create
file_name, because that buffer is the same length. Increasing the size
of file_name to 256 permits using all of whoami.
The name is also no longer truncated to 20 chars when writing the log.
All games should now be able to handle 79-character names without
collisions. Anything more would break save compatibility.
