Add the "-df <duid file>" option to the client code in order to make it easier to share DUIDs between a v4 instance and a v6 instance. This option instructs the client to search the duid file for a DUID if it didn't find one in the main lease file. In addition add the infrastructure for running ATF tests for the client and write some ATF tests for this patch.

/* Tests to see if the routine to read a secondary lease file
|
|
* for the DUID works properly. The tests:
|
|
* Test file x:
|
|
* no test file - should result in no duid
|
|
* Test filx 0:
|
|
* A test file but no DUID def, no duid
|
|
* Test file 1:
|
|
* Can it read a single DUID in the file?
|
|
* Test file 2:
|
|
* Can it find a second DUID in the file after a good lease and
|
|
* a badly formatted lease?
|
|
* Test file 3:
|
|
* Can it find a later DUID after a good one and a bad one?
|
|
* and to give a bit more coverage test file 1 should use LLT
|
|
* test file 2 should use LL and test file 3 should use LL for
|
|
* the first one and LLT for the third one.
