[PATCH v4 08/12] test: Use paths in __STATEDIR__ instead of 'temp' and 'tempdir' directives

[David Gibson <david@gibson.dropbear.id.au>]

[-- Attachment #1: Type: text/plain, Size: 21185 bytes --]

Instead of using the 'temp' and 'tempdir' DSL directives to create
temporary files, use fixed paths relative to __STATEDIR__.  This has two
advantages:
  1) The files are automatically cleaned up if the tests fail (and even if
     that doesn't work they're easier to clean up manuall)
  2) When debugging tests it's easier to figure out which of the temporary
     files are relevant to whatever's going wrong
