[Xen-devel] [OSSTEST PATCH 02/10] Flight restriction: Introduce restrictflight_arg and restrictflight_cond

[Ian Jackson <ian.jackson@xxxxxxxxxxxxx>]

Provide the new functions which we will eventually use everywhere.

* Introduce restrictflight_arg which can be used in an argument loop.
* Introduce restrictflight_cond which generates a SQL condition.
* Have restrictflight_cond's value include surrounding ( ) for safety.
* Use the above in sg-report-host-history, renaming $maxflightcond.

No overall functional change.
