Call abort() on undefined or sketchy integer behavior.
Protects against integer overflow attacks.
Tested on Nexus 5 and Nexus 9 with no obvious problems.

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.

/system/etc/recovery.img defaults to 0644. Change it to 0440.

(cherry picked from commit b602e6f9a3)
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.

When the ramdisk is built into the system image, we need to create
those folders during the build.

If /dev/kmsg already exists, it's unnecessary for klog_init()
to create it's own copy. This avoids needing to grant the mknod
permission to everyone who uses kmsg. Typically the only time
/dev/kmsg doesn't exist is before ueventd starts.

Also simplifies the Darwin implementation of gettid, because
apparently libbacktrace had a better way of doing it.

Fix broken mips64 build by replacing mips32r2-only android_memset.S.
Use HW-bonded pairs of 64-bit stores to fill 128 bits/cycle.
Rely on HW automatic cache prefetch optimizations.
Software cache prefetching is counterproductive on next mips cores.
New method is coded in C, and also works okay on non-Mips architectures.

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.

Intention is to read from ${OUT}/system/etc/fs_config_dirs and
${OUT}/system/etc/fs_config_files on host. And
/system/etc/fs_config_dirs and /system/etc/config_files
on target systems.

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.
