a73df601b7 tombstoned: allow intercepts for java traces.
All intercept requests and crash dump requests must now specify a
dump_type, which can be one of kDebuggerdNativeBacktrace,
kDebuggerdTombstone or kDebuggerdJavaBacktrace. Each process can have
only one outstanding intercept registered at a time.

There's only one non-trivial change in this changeset; and that is
to crash_dump. We now pass the type of dump via a command line
argument instead of inferring it from the (resent) signal, this allows
us to connect to tombstoned before we wait for the signal as the
protocol requires.

Test: debuggerd_test

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.
