Josh Gao 57f58f8e4a crash_dump: fetch process/thread names before dropping privileges. 
Processes that don't have dumpable set to 1 cannot have their
process/thread names read by processes that don't have all of their
capabilities. Fetch these names in crash_dump before dropping
privileges.

Josh Gao 9eb4eb1811 libdebuggerd: add compatibility shim.

This will be reverted after fixing up the uses on the other end.

Remove debuggerd in favor of a helper process that gets execed by
crashing processes.
