df8cb05498 tombstoned: fix a race between intercept and crash_dump. 
Previously, there was no way to detect when tombstoned processed an
intercept request packet, making it possible for a intercept request
followed by a crash_dump being processed in the wrong order.

Add a response to intercept registration, to eliminate this race.

Test: debuggerd_test

e1aa0ca58a debuggerd_handler: implement missing fallback functionality. 
Allow the fallback implementation to dump traces and create tombstones
in seccomped processes.

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

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

218f7fb68e debuggerd: report crashes even when out of file descriptors. 
Use nasty clone hacks to let us close random file descriptors to be
able to connect to debuggerd when the fd table is full.

a04c80255c debuggerd: remove unnecessary arguments. 
These were previously required when bionic used tgkill to reraise
signals, but now that we use rt_tgsigqueueinfo to reraise signals, they
are no longer necessary.
