tombstoned: Support java trace dumps.
The changes here involve :
- Creating and opening a new socket to receive trace dump requests on. Having
different sockets allows us to install different sets of access control rules.
- A minor refactor to allow us to share common pieces of implementation
between the java and native dumping code. This will also allow us to
add a unit test for all file / directory related logic.
There are two java trace specific additions here :
- We use SO_PEERCRED instead of trusting the PID written to the seocket
because requests come in from untrusted processes.
- Java trace dumps are not interceptible.
kJavaTraceDumpsEnabled is set to false for now but the value of the flag
will be flipped in a future change.
Bug: 32064548
Test: Manual; Currently working on a unit_test for CrashType.

Actually don't start tombstoned until /data is mounted.
Bug: http://b/34461270
Test: boot is actually faster
Test: tombstoned still started by init

init: don't start tombstoned until /data is mounted.
When vold mounts the encrypted /data partition, it first checks for and
kills processes that have open fds to the tmpfs placeholder at /data.
This resulted in a 20 second boot-time regression (vold's timeout period)
when tombstoned was started before vold.
Bug: http://b/34461270
Test: boot is faster, no messages from vold in console spew
Test: tombstoned still started by init

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