Snyc tnftp with NetBSD:

Fix numerous WARNS issues.

Rename internal getline() function to get_line() to prevent conflicts.

Rename argument from "bool" to "val".

Parse HTTP 'Date' entries in the `C' locale rather than the user's.

Avoid NULL dereference in log output if the command line parser
failed to extract a port number from the URL.

Use AF_INET instead of AF_UNSPEC as the default family if
!defined(INET6).

In ftpvis(), prevent incomplete escape sequences at end of dst,
and ensure NUL-termination of dst.  Also tweak for readibility.
