Steven Smith has pointed out a few minor errors and provided some more information about the behaviour of old xenstoreds. I''ve documented the relevant facts, as I understand them, in the attached documentation patch. I''m going to follow this up with another patch about size limits for xenstore messages. Ian.

The patch below:
* Documents the existing 4kby size limit on xenstore message payloads
* Causes xs.c in libxenstore to fail locally rather than violating
said limit (which is good because xenstored kills the client
connection if it''s exceeded).
* Introduces some limits on path lengths in xenstored. I trust
no-one is using path lengths >2kby. This is good because currently
a domain client can create a 4kby relative path that the dom0 tools
cannot access since they''d have to specify the somewhat longer
absolute path.
* Removes uses of the host''s PATH_MAX (!)
