List of xids from dtx.recover is not as expected (RHEL 4)

+++ This bug was initially created as a clone of Bug #458656 +++
The resonse for dtx.recover should include a list of all the xids currently in the prepared state; at present it only includes those that were in prepared state at time of last recovery.
--- Additional comment from firstname.lastname@example.org on 2008-08-14 14:40:04 EDT ---
The call to BdbMessageStore::collectPreparedXids() was using the prepared list obtained at time of recovery, but this call needs to provide a current list, no matter when called. The ability to ignore transactions when reading was added to class rmgr, and a subclass of JournalImpl (called TplJournalImpl) was created which implements the ignore as standard practice when calling read. This enables reads of pending transactions from this list. Now BdbMessageStore::collectPreparedXids() re-reads the transaction prepared list (TPL) before returning the XID list.
This is a somewhat expensive solution - but is sufficient for the time being as collectPreparedXids() is currently only called on recovery in the broker.
Fixed in r.2305 (trunk), r.2306 (1.0 branch)
RHTS test MRG_Messaging/qpid_xids_fails_bz458656 runs qpid.tests_0-10.dtx tests (which are passing) that proves that xid.recover response is now OK (->VERIFIED)
