.. for ART and the frameworks to link against. In the new stack dumping
scheme (see related bug), the Java runtime will communicate with
tombstoned in order to obtain a FD to which it can write its traces.
Also move things around to separate headers that are private
implementation details from headers that constitute the public debuggerd
API. There are currently only three such headers :
- tombstoned/tombstoned.h
- debuggerd/client.h
- debuggerd/handler.h

If send_signal failed, debuggerd_trigger_dump should return
instead of further dealing

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.

Use an intermediate pipe to detect and report when a requested dump has
completed.

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

Use nasty clone hacks to let us close random file descriptors to be
able to connect to debuggerd when the fd table is full.

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.
