###@###.### from CTE has ported the deadlock detector built into the
HotSpot VM up to the Serviceability Agent. This is very useful as it allows
deadlock detection to be run on hung or crashed VMs and core files.
In order to make this work it is necessary to move a couple of definitions
to header files as well as add a couple of entries to constant tables in the VM.
None of these changes have any impact on the product code. We want to make these
changes for 1.4.1_01 so they are present going forward. (They will be added
separately to 1.4.0_04 and main/baseline.)
