[Xen-devel] [OSSTEST PATCH v14 18/24] TestSupport: Introduce target_cmd_stashed

[Anthony PERARD <anthony.perard@xxxxxxxxxx>]

This works like target_cmd, but takes a ref to a filename as argument
and stash the output of the command then return a path to the stashed
output.

Notes:
    Changes in V14:
    - Use filename for error message instead of file handle.
