Currently if someone changes the date on the host, xenconsoled may
behave incorrectly due to the use of gettimeofday for the rate control
algorithm. For example I was able to hang the console connected to a
guest just setting the date forward 20 years. To solve the problem we
need to use a time source that doesn't change start point, that is
clock_gettime with CLOCK_MONOTONIC. The only bad side effect is that
it introduces a dependency to librt, but I think is well worth it.

- 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)

- convert raw "install" command to use $(INSTALL)
- convert some $(INSTALL) to $(INSTALL_DATA) as appropriate
- modify the specific $(INSTALL) definitions to use -p.

* Move .PHONY directives next to targets,
this makes them a lot harder to miss
* Add missing .PHONY directives
* Remove nonexistent .PHONY directives

and xenconsole out of /usr/libexec/xen and into one of /usr/lib/xen/bin or
/usr/lib64/xen/bin. Remove all the PATH hacking inside Xend, and rely upon
the PATH being set correctly from outside. Added an auxbin module for
handling the hacky stuff.
Replace the few /usr/bin/python bang paths with /usr/bin/env python.
