Move determination of socket buffer sizes from startup to the first time
a socket is used. The previous code structure assumed that AF_INET
sockets were always available, which is an invalid assumption on
IPv6-only systems.

Copy lukemftp to its new home, tnftp. I'm doing this in stages so as to
not confuse the CVS exporter.

This commit was generated by cvs2svn to compensate for changes in r146309,
which included commits to RCS files with non-trunk default branches.

Import latest NetBSD version...changes:

* Whitespace and gcc 4.x fixes.
* Fix deallocation bug in fetch.c.
* Implement timeouts for accept(2) and connect(2),
which accept timeout values with '-q quittime'.
(intended to help with active mode through firewalls)
* Fix bin/77158 by Ryoji Kanai <rkanai@eeye.com>.

Import the latest CVS version of lukemftp.

Short list of changes:

* SIGINT termination from auto-fetch.
* Less trusting of remote filenames during auto mgets.
* Improved RFC2616 compliancy.
* Fix globs when using ftp reget (from mat@).
* Limit send buffer size.

Import the latest (4/26/04) CVS lukemftp. This adds the ability to
have a prefix string on the progressbar and brings in a patch by mux@
to fix the condition when connect() returns EINTR.

Import latest CVS lukemftp.

Import the June 15, 2003 CVS version of NetBSD's ftp + patchset to fix
header file differences between FBSD and NBSD. Like lukemftpd, the
portable version of lukemftp lags too far behind CVS.

This import includes several big fixes plus a cleaned up manpage.

Import lukemftp-1.6-beta2.

Import of LukeM's ftp client, version 1.5.
