- [atomicio.c authfd.c scp.c serverloop.c ssh.h sshconnect.c sshd.c]
move atomicio into it's own file. wrap all socket write()s which
were doing write(sock, buf, len) != len, with atomicio() calls.
- [auth-skey.c]
fd leak
- [authfile.c]
properly name fd variable
- [channels.c]
display great hatred towards strcpy
- [pty.c pty.h sshd.c]
use openpty() if it exists (it does on BSD4_4)
- [tildexpand.c]
check for ~ expansion past MAXPATHLEN
- Modified helper.c to use new atomicio function.
- Reformat Makefile a little
- Moved RC4 routines from rc4.[ch] into helper.c
- Added autoconf code to detect /dev/ptmx (Solaris) and /dev/ptc (AIX)
