a new patch is included in this mail (pre-pre-alpha!) for adding ftp
support to stunnel-4.11
here are some notes:
1) only tested under linux. debian 3.1 (testing), gcc version 3.3.5
(Debian 1:3.3.5-13)
2) ftp_alloc_port() in ftp.c is not yet finished. just a demo;
3) works with both ucontext and pthread
4) libwrap support is not tested. should be OK. inted support is not
tested, but it should be OK too (no related code changed);
5) still contains memory leaks.
6) client compatibility test: just FlashFXP 3 (implicit ssl, secure both
list and data transfer) now.
7) bug #7 in last mail is resolved.

client compatibility test and bug reports are welcome.
