PS-E, gen-sidai-hosts/ and host/ files...

First, I'd appreciate it if folks would try the :bootstrap procedure in
sidai/gen-sidai-hosts/ and compare the resulting .xml files with those in
../host/, and let me know about any significant differences.

Assuming all goes well, I'd like to lose the checked-in contents of the
host/ directory and go to build-time configuration of these files.

Speaking of which, I suspect that someday soon we'll need to go from:

	CPU-OS.xml
	OS.xml

to:

	CPU-OS-OSVER.xml
	CPU-OS.xml
	OS-OSVER.xml
	OS.xml

Finally, I think the existing PS-E stuff will also turn out to be a lose.  I
think we'll have to look at what Berto and I have done with PIKT in this
regard.  A fragment of configure.in for this is:

dnl psparse=1 will handle output from `ps' that contains PID PPID command,
dnl           including solaris & aix
dnl psparse=2 will handle output from `ps' from linux and sunos
dnl psparse=3 will handle output from `ps' from hpux & irix

psopts=""
psparse=""

    psopts="-efo pid,ppid,comm"
