[PATCH 22/29] libxl: Introduce DOMAIN_DESTROYED error code

[Ian Jackson <ian.jackson@eu.citrix.com>]

This is currently reported only by the bootloader code, if the domain
is destroyed while the bootloader is running.

In the future it would be nice to return it for other circumstances
where the domain existed when the operation started but subsequently
vanished.
