The problem is both face unlock and camera application try to open
the hardware camera at the same time. A new camera open API is
added to let face unlock take the camera away from the existing
client. The release message is used to notify the existing client,
so it has time to release the hardware camera and clean up.
If existing client tries to use the camera after it is released,
the method will return error. It is still possible that the
camera has been taken and the existing client has not got the
notification. When any method returns error, the existing client
can use ping command to check whether the camera has been released.
If yes, the client can silently finish the app itself or show a
toast if it wants.

Do not strip the Thumb bit on ARM. This fixes an off-by-one
issue that could happen when resolving a PC that was at the
very beginning of a Thumb function, since the symbol table would
have the Thumb bit set but since we stripped the bit from our

one listed in the symbol table. It's also quite useful to see
whether a given function is executing in Thumb mode just by glancing
at the PC.

Keep track of whether memory maps are readable. Use the information
in try_get_word to try to avoid accidentally dereferencing an invalid
pointer within the current process. (Note that I haven't ever
seen that happen during normal unwinding, but it pays to be
a little more careful.)
Refactored try_get_word a little to make it easier to pass it the
needed state for validation checks by way of a little memory_t struct.
Improved how the memory map for the current process is cached. This is
important because we need up to date information about readable maps.
Use a 5 second cache expiration.
Improved the PC -> LR fallback logic in the unwinder so we can
eke out an extra frame sometimes.
Fixed a bug reading ELF program headers. The phnum & phentsize
fields are half-words. We were incorrectly interpreting
phnum as a whole word.
Used android_atomic_* operations carefully in the unwinder
to prevent possible memory races between the dumper and the dumpee.
This was highly unlikely (or even impossible due to the presence
of other barriers along the way) but the code is clearer now about
its invariants.
Fixed a bug in debuggerd where the pid was being passed to have
its stack dump taken instead of the tid, resulting in short
stacks because ptrace couldn't read the data if pid != tid.
Did a full sweep to ensure that we use pid / tid correctly everywhere.
Ported old code from debuggerd to rewind the program counter back
one instruction so that it points to the branch instruction itself
instead of the return address.

* 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)

To workaround a binary incompatiblity with Motorola's ril.so, I had to
temporarily provide the old constructor for NetlinkListener as well as
a new contructor that takes an additional format argument.
There's still a slight chance of a problem because the size of the
NetlinkListener has changed with the addition of the
mFormat member, but so far I've not seen any obvious problem with that
incompatiblity.
Another way we could have worked around the incompatiblity is to have
netd (the main user of the new format argument to NetlinkListener) keep
track of the format itself in it's NetlinkHandler (derived from NetlinkListener)
and supply it's own version of onDataAvailable() that's almost 100% identical
to NetlinkListener's except for the decode() call. That would allow us
not to modify NetlinkListener at all. Worth considering but I think it's
more properly divided right now and we just have to make Motorola fix their
code (and ideally not use our private APIs).
This change should be reverted when Motorola's has fixed their ril to
either not use our private APIs or to use our updated ones.

This patch moves the definition of ANativeWindow from frameworks/base into
system/core. We move ANativeWindow for two reasons.
Firstly, the native-window interface may need to be used by lower-level code
than the framework. Such code (such as the camera HAL) is not allowed to use
definitions from frameworks/base, since the latter is stacked on top of the
former. Thus moving (the interface definition) ANativeWindow under system/core
lowers the level at which we can work with windows.
Secondly, this enables an implementation of ANativeWindow that lies outside of
frameworks, enabling quick initial bringup of graphics.

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.
