These patches affect only TPF.

They are driven by changes to the TPF operating system:
     updates in shutdown processing to accommodate new code in TPF's
Internet Daemon
     updates to allow non-blocking file descriptors on TPF now that our
select() supports non-socket file descriptors
     changes to os.c to take advantage of TPF's newly enhanced version
of fork and exec
     moving TPF-specific printf's for the -V option from http_main.c to
os.c
