xenstored: allow guest to shutdown all its watches/transactions
During kexec all old watches have to be removed, otherwise the new
kernel will receive unexpected events. Allow a guest to reset itself
and cleanup all of its watches and transactions.
Add a new XS_RESET_WATCHES command to do the reset on behalf of the
guest.
(Changes by iwj: specify the argument to be a single nul byte. Permit
read-only clients to use the new command.)
