- Merged more OpenBSD changes:
- [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)
