Hash functions rely on overflow behavior, so whitelist them.
ATRACE_TAG_NOT_READY: use an unsigned constant when shifting bits.
Otherwise, the value overflows on shift. The users of this constant
assign it to a uint64_t variable.

and run fsck with -f on clean shutdown instead.
With -f, fsck.f2fs always performs a full scan of the /data
partition regardless of whether the partition is clean or not.
The full scan takes more than 2 seconds on volantis-userdebug
and delays the OS boot.
With -a, the command does almost nothing when the partition
is clean and finishes within 20-30ms on volantis-userdebug.
When the partition has an error or its check point has
CP_FSCK_FLAG (aka "need_fsck"), the command does exactly the
same full scan as -f to fix it.

cutils/endian.h provides the helpers defined in endian(3), either by
pulling in the OS's built-in endian.h (where available) or recreating
them using GCC builtins.

Several people have been independently confused about when this gets
built and why over the past couple of days.

This also fixes the bug where we were always testing against the fake
strlcpy we provide for glibc/Windows rather than the Android one.
This also removes some unnecessary library dependencies.
This also builds all the cutils tests for the host (static and dynamic).

Also make important events in init's life NOTICE rather than INFO,
and ensure that NOTICE events actually make it to the kernel log.
Also fix the logging so that if you have a printf format string
error, the compiler now catches it.
Also give messages from init, ueventd, and watchdogd distinct tags.
(Previously they'd all call themselves "init", and dmesg doesn't
include pids, so you couldn't untangle them.)
Also include the tag in SELinux messages.

This change defines atrace_* functions for the host that act as
no-ops, which makes it easier to add tracing in ART.

On 64 bit systems, calls to dump_backtrace_to_file or dump_tombstone
try and directly contact the correct debuggerd (32 bit vs 64 bit)
by reading the elf information for the executable.
Unfortunately, system_server makes a call to dump_backtrace_to_file
and it doesn't have permissions to read the executable data, so it
defaults to always contacting the 64 bit debuggerd.
This CL changes the code so that all dump requests go to the 64 bit
debuggerd, which reads the elf information and redirects requests for
32 bit processes to the 32 bit debuggerd.
Testing:
- Forced the watchdog code in system_server to dump stacks and
verified that all native stacks are dumped correctly.
- Verified that dumpstate and bugreport still properly dump the native
processes on a 64 bit and 32 bit system.
- Intentionally forced the 64 bit to 32 bit redirect to write only a
byte at a time and verified there are no errors, and no dropped data.
- Used debuggerd and debuggerd64 to dump 32 bit and 64 bit processes
seemlessly.
- Used debuggerd on a 32 bit system to dump native stacks.

Under some unknown circumstances, debuggerd could become unresponsive.
If you try and take a bugreport during this time, it will hang forever.
Adding functions that have a timeout will allow dumpstate to stop if
dumping is taking too long.

extend to catch and decode them. To avoid escaping issues, the raw

This means that code that uses libcutils no longer has to ensure that
it's set ANDROID_SMP in the calling code's Android.mk for this to
function correctly.

This should not be committed until win_sdk and aarch64 builds are
fixed in the presence of this CL.
This reverts commit 2789faabfa.
We additionally remove uniprocessor support from the earlier CL,
thus avoiding a potential compiler code reordering issue.

On 64 bit systems, calling dump_backtrace_to_file will automatically
call debuggerd64. If the process to dump is actually 32 bit, this
creates an unrecognizable dump backtrace. Modify the code to check the
type of the process and connect to the appropriate debuggerd process.
This change refactors both the tombstone and backtrace functionality to
allow both to work properly on 64 bit systems when dealing with mixed
processes.
