Show the symbol offset, when available.
Centralized formatting of native stack traces in libcorkscrew.
It's handy for automated tools if all stacks look the same.
Since we already made them all look them same, we might as well
do the formatting in just one place.
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
PC, we would be looking for an address one byte before the
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.

The access control changes allow us to just use Nfc.apk with
the regular platform certificate, instead of the custom signed
NfcGoogle.apk. So we can compeltely get rid of vendor/google/apps/NfcGoogle
and just build it out of packages/apps/Nfc now.
The package name is also reverted from com.android.nfc3 to com.android.nfc
The NFC uid needs to get bumped (25 to 27) to allow the cert change.

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.

Supports collecting the stack trace of the current thread,
another thread in the same process, or a thread in a
different process (using ptrace).

The problem was: if a socket is shared between SocketListener and another
thread, only if the last reference is removed by SocketListener can the socket
be closed, otherwise the socket will leak. This sometimes happens in netd's
dnsproxyd.
This change let the SocketClient own the socket and close the socket when
the SocketClient is destructed.

- Provide a function to add and delete IPv4/IPv6 addresses
using netlink.
- Provide a function that clears all IP addresses on an
interface that can be used by netd.
Also, a couple of cleanups:
- Update the header file to match reality, and include the
header file in the implementation. Also fix a caller that
has an incorrect method signature.
- Fix whitespace in Android.mk.

* 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)

This can be launched from an 'on charger' section in init, which
is processed if androidboot.mode=charger is supplied on kernel
command line.
This is a standalone binary that has a simple "user interface"
and allows the standard production kernel to run while charging.
This removes the burden from the bootloader to get low-power mode
working.
Currently, the device will "power-on" (i.e. reboot) into normal
mode if the power key is pressed for X seconds, and will also
power down the device if the usb/ac cable is removed for Y seconds.

this is needed if a display/gpu driver needs to create
service threads that can block the main ui thread.
to avoid priority inversions, these must run at
