The RDNSS options (RFC 6106) used to configure DNS servers via
router advertisements are passed from the kernel to userspace via
RTM_NEWNDUSEROPT netlink messages. Add code to NetlinkEvent to
parse them.
Also fix a compiler warning and a couple of style issues.

The change to enable address tracking via netlink incorrectly
changed the subsystem of rtnetlink events from "net" to
"interface". This broke interface add/delete notifications,
which come from the kernel with subsystem "net".
Switch back to "net" and deal with address tracking via new
action codes instead of a new subsystem.

This adds support for parsing RTM_NEWADDR and RTM_DELADDR
netlink messages received on netd's netlink socket and
formatting them them so NetlinkHandler can process them.
Address changes are notified in subsystem "address". Interface
changes, which used to be notified in subsystem "net", are now
notified in subsystem "interface" to avoid confusion.

In order to be explicit in the Backtrace::Create() calls, adding a couple

Fix a race where multiple threads could be attempting to unwind the threads

The old code was essentially trying to be C++ in C and was awkward. This
change makes it all objects with a thin layer that C code can use.
There is a C++ backtrace object that is not very useful, this code will
replace it.
This change also includes moving the backtrace test to a gtest, and adding
coverage of all major functionality.

This adds a small EC library that is capable of verifying a signature of
SHA256 with ECDSA on the NIST P-256 curve.

This library will be used to abstract away getting backtrace
data from how it is implemented. This is the first step to
replacing libcorkscrew with libunwind.

- adds a library to compute the SHA-256 hash
- updates the RSA verifier to take an argument specifying either SHA-1
or SHA-256
- updates DumpPublicKey to with new "key" version numbers for
specifying SHA-256
- adds new argument to adb auth code to maintain existing behavior

Before this change, FUSE lookup() would have the side effect of
creating the directory on behalf of apps. This resulted in most
directories being created just by Settings trying to measure disk
space. Instead, we're switching to have vold do directory creation
when an app doesn't have enough permissions.
Create fs_mkdirs() utility to create all parent directories in a
path as needed. Allow traversal (+x) into /storage directories.
Fix FUSE derived permissions to be case insensitive. Mark well-known
directories as .nomedia when created.

Changes the FUSE daemon to synthesize an Android-specific set of
filesystem permissions, even when the underlying media storage is
permissionless. This is designed to support several features:
First, apps can access their own files in /Android/data/com.example/
without requiring any external storage permissions. This is enabled
by allowing o+x on parent directories, and assigning the UID owner
based on the directory name (package name). The mapping from package
to appId is parsed from packages.list, which is updated when apps are
added/removed. Changes are observed through inotify. It creates
missing package name directories when requested and valid.
Second, support for separate permissions for photos and audio/video
content on the device through new GIDs which are assigned based on
top-level directory names.
Finally, support for multi-user separation on the same physical media
through new /Android/user/ directory, which will be bind-mounted
into place. It recursively applies the above rules to each secondary
user.
rwxrwx--x root:sdcard_rw /
rwxrwx--- root:sdcard_pics /Pictures
rwxrwx--- root:sdcard_av /Music
rwxrwx--x root:sdcard_rw /Android
rwxrwx--x root:sdcard_rw /Android/data
rwxrwx--- u0_a12:sdcard_rw /Android/data/com.example
rwxrwx--x root:sdcard_rw /Android/obb/
rwxrwx--- u0_a12:sdcard_rw /Android/obb/com.example
rwxrwx--- root:sdcard_all /Android/user
rwxrwx--x root:sdcard_rw /Android/user/10
rwxrwx--- u10_a12:sdcard_rw /Android/user/10/Android/data/com.example
These derived permissions are disabled by default. Switched option
parsing to getopt().

Making an object Flattenable doesn't force it to
become virtual anymore. For instance, Fence and GraphicBuffer
are now non-virtual classes.
Also change Flatennable protocol a bit so that it updates
its parameters (pointers, sizes) to make it easier
to implement a flattenable in terms of other flattenables.

when libutils is statically linked, the ordering of the static
initializer is not guaranteed and therefore it's unsafe to use
empty static strings: e.g.:
static String8 sThisStaticStringIsNotSafe;
instead, this new constructor can be used:
static String8 sThisStaticStringIsSafe(kEmptyString);

background:
we have some code to fix-up the IDs of references when
using RefBase's DEBUG_REFS when those refs are managed by
arrays wp<> or sp<> (this is because wp<> / sp<> don't have
a trivial ctor when DEBUG_REFS is enabled, and Vector
treats them as trivial for obvious performance reasons)
this is complicated by the fact that we don't want to have
to recompile everything when enabling DEBUG_REFs (i.e.: the
Vector code cannot know wheter it's enabled or not for its
template stuff).
problem:
there was a bug in the fix-up code for wp<> which was trying
to access the weakref_impl from the RefBase* however, this was
moronic since RefBase could have been destroyed if there wasn't
any more strong refs -- and this happned. Instead we need to get
the weakref_impl directly from the wp<>
