575941115e crash_dump: clear the default crash handlers. 
crash_dump is a dynamic executable that gets the default crash dumping
handlers set by the linker. Turn them off to prevent crash_dump from
dumping itself.

Bug: http://b/34472671
Test: inserted an abort into crash_dump

b64dd85c94 debuggerd_handler: actually wait for pseudothread to exit. 
Occasionally, the pseudothread wouldn't exit in time after unlocking
the mutex to get crash_dump to proceed, resulting in spurious error
messages. Instead of using a mutex to emulate pthread_join, just
implement it correctly.

cbe70cb0a8 debuggerd: advance our amazing bet. 
Remove debuggerd in favor of a helper process that gets execed by
crashing processes.
