In an earlier code review it was pointed out that there was something
very weird about fail_errno. It didn't seem to make sense that we'd
often try to continue after reporting failure. This patch cleans up
all that and assumes that if we've reported failure to the client,
we should stop what we're doing.

We can double the speed of "adb sync" (on N9) if we increase SYNC_DATA_MAX
from 64KiB to 256KiB. This change doesn't do that, because I still haven't
managed to plumb through the information about whether we're a new adb/adbd
to file_sync_client.cpp and file_sync_service.cpp. But this is already a big
change with a lot of cleanup, so let's do the cleanup and worry about the
intended change another day...
This change does improve performance somewhat by halving the number of
lstat(2) calls made on the client side, and ensuring that most packets are
sent with a single write. This has the pleasing result of making the null
sync on an AOSP N9 go from just over 300ms to around 100ms, which means it
now seems instantaneous (https://en.wikipedia.org/wiki/Mental_chronometry).

* Hashing functions rely on integer overflow behavior.
Mark those functions as safe.
* abort() if a passed in size_t value is greater than
UINT32_MAX. This can occur on 64 bit builds where size_t
is larger than uint32_t.
* Special case the index lookup for an empty sorted vector.
Without the special case, size() == 0, and size()-1 underflows.

It is unsafe to use /data/local/tmp. Use our own temporary
directory under /data/misc/crash_reporter.

* Explicitly specify default .align 0.
* Use standard ldmfdlo instruction.
* Before and after gas outputs are identical,
with align 0 sections.
* Objdump showed .text/.data/.bss section alignment
attributes are 2^0 from gas and 2^2 from llvm
assembler. These .S files might be working when
compiled by gas, but llvm assembler's output should
be more correct or conservative.

Services definitions for core services are now bundled with the source
for the service itself in the form of <service name>.rc. These
individual .rc files are now located in /system/init/... and are
parsed when the system partition is mounted.

When init queues a trigger, it actually enqueues all of the Actions
that match with that given trigger. This works currently because
all init scripts are loaded and therefore all Actions are available
before init starts queueing any triggers.
To support loading init scripts after init has started queueing
triggers, this change enqueues Trigger objects instead of their
matching Actions. Each Trigger object then matches its associated
Actions during its execution.
Additionally, this makes a few cosmetic clean ups related to triggers.

This patch is used to fix two Bugs in backed_block.c
First, fix wrong comparing string way: we should use strcmp rather than
just compare their address. Second, fix using illegal memory risk in
bbl->last_used pointer. When entering queue_bb function,
bbl->last_used = new_bb, but in the following code if
queue_bb(xx, bb, new_bb) return ok, the space of new_bb is released. So
next time, if you use bbl->last_used pointer, may cause segment fault !
