Also tid == 0 maps to gettid() on platforms that support it.
This is needed by mediaserver code that was formerly using
the old C++ API.

This change adds a layer of indirection to uevent's

qsort_r() is declared differently on BSD and GNU libc and

Provide qsort_r_compat() which should work everywhere.

This will make it easier to add additional policies (cgroups) if needed.
Also added comments to the sched_policy APIs.

When removing one entry, we can't just remove it from the map since
key will not be freed. So, instead, search through the map for the key
and free it once it is found.

The strftime_tz() function is not a standard C library function and should not
appear in <time.h>. Instead, it is being moved to <bionic_time.h>, a private
header only available to platform libraries.

* Add support for
deleteTagData(tag, uid)
setCounterSet(counterSetNum, uid)
setPacifier(on)
* Add resource tracking
(If only kernel process termination had a hook)
Because the xt_qtaguid netfilter module needs to keep track of
tagged sockets, it needs a way to know when the process owning
the socket has died.
Normally the app will untag the sockets. But not on crash.
So the process opens the qtaguid misc dev, which is closed on crash,
at which point the xt_qtaguid can force-untag the processes sockets,
and thus allowing their refcount to go down and release them.
* Add pacifier support
Add function to enable/disable pacification of the xt_qtaguid
kernel module. (mostly for debugging)

Backport Iee1ca9b7defd6
This now passes:
$ adb shell am instrument -w -e class android.os.SystemPropertiesTest \
com.android.frameworks.coretests.systemproperties/android.test.InstrumentationTestRunner
(which tests setting and re-reading back system properties in a loop)
This patch depends on I110b653a which moves property setting
from libcutils into bionic.

Ext4 filesystems like to be unmounted before rebooting. The Android system
doesn't have a traditional Linux init setup, and shutting down the system
was not much more than calling sync(2) and reboot(2). This adds a new
function to libcutils called android_reboot(). By default, it calls sync()
and then remounts all writable filesystems as read-only and marks them clean.
There is a flag parameter in which the caller can ask for sync() not to be
called, or to not remount the filesystems as read-only. Then it will call
reboot(2) as directed by the other parameters. This change also updates
adb, init and toolbox to call the new android_reboot() function.
Fixes bugs 3350709 and 3495575.

shared among all x86 targets.

Added new atomic functions, renamed some old ones. Some #defines have
been added for backward compatibility.
Merged the pre- and post-ARMv6 implementations into a single file.
Renamed the semi-private __android_membar_full_smp to USE_SCREAMING_CAPS
since that's more appropriate for a macro.
Added lots of comments.
Note Mac OS X primitives have not been tested.

Added atomic-inline.h. Added a platform-specific memory barrier call
there.
Added android_atomic_acquire_cmpxchg() and android_atomic_release_store().
Not tested on Mac OS X or SH.
Added memory barrier calls to linux-x86 atomics. Mac OS X has barrier
functions already. sh isn't really SMP-ready. linux-arm needs work
(to be done in a separate change).
Updated the makefile to make the SMP state visible to the code here.
Note that host binaries are NOT built with SMP enabled; while our hosts
are very likely SMP, it's not worth figuring out e.g. whether it's okay
to use the SSE2 mfence instruction or have to use something else. We
haven't had barriers enabled in host tools before, so there's probably
no need to stat now.
Removed quasiatomic 64-bit calls (now part of Dalvik).

Re-use the file descriptor to change the cgroups. There's a fast path
in the kernel for the case where the value's already uncahnged. Also,
this is okay because the kernel ignores the write offset. This is
essentially a ioctl-ish/datagram interface, despite being a fd we're
writing to.
This reduces Dalvik->Dalvik void/void Binder calls on Sapphire from
~1.2 to ~0.8 ms. This is a bit slower than the ~0.7 ms we get
avoiding the write altogether.
strace confirms:

This routine allows creating a contiguous mspace from raw mapped memory.
In turn, this will enable preallocation of the 3 heap spaces, which will help
remembered sets and zygote/app checks given pointer values.
POSIX seems to have chosen open_memstream() over the BSD variant. We
want something for Dalvik that will work on both GNU/Linux and Android,
so this is open_memstream() implemented in terms of BSD funopen().
For Windows there's just a stub that calls abort().
I'm putting this in libcutils since it seems inappropriate for bionic
(which provides the BSD alternatives) but isn't Dalvik-specific.
