Xen devel - Oct 2007 - [PATCH][TOOLS] console: portability fixes

Hi!

Attached patch adds portability fixes:
- Use openpty(), which does the same as the sequence
  of open(), grantpt(), unlockpt(), ptsname(), tcgetattr()
  => simplifies code
- Check return code from tcsetattr()
- sprintf() -> snprintf()
- OpenBSD lacks POSIX grantpt() and unlockpt()
   => requires use of openpty()
- Solaris lacks POSIX openpty() via feedback from SUN (John Levon)
   => implement openpty() for Solaris, tested and ok''d by SUN (John
Levon)
