1. Accept that parseNetlinkMessage can only parse one netlink
message, because its way of returning output is to modify its
member variables (mAction, mParams, etc.). Currently, it
loops through all the messages it finds, updating its member
variables as it goes along, and always returns true at the end
of the buffer. This has the following problems:
1. Since the function always returns true even when no
messages were parsed, the caller has no way to know if
parsing succeeded, and we get lots of "No subsystem found
in netlink event" logs if the buffer did not contain any
valid messages we were interested in.
2. If there are multiple messages in the buffer, all but the
last message will be silently ignored.
3. If there are multiple messages and previous messages have
more parameters than the last one, the resulting event will
have a mixture of parameters from multiple messages.
Instead of doing all this, change the contract to "parse the
first valid message of interest in the buffer and return true,
or return false if there were no such messages", and update
the code and the comments accordingly.
2. Modify the caller (NetlinkListener) so it doesn't log an
error when parseBinaryNetlinkMessage returns false, because
this can now simply mean that we weren't interested in that
particular message. parseBinaryNetlinkMessage already logs
more informative errors.
3. Provide utility functions to check received message lengths and
to convert message types to message names.
4. Simplify logging duplicate attributes.
5. Use the appropriate IFLA_xxx macros instead of rolling our own
code to parse link state messages.
6. Move all the parsing code out to per-message-type parsing
functions to order to simplify parseBinaryNetlinkMessage.

I haven't seen this warning in any AOSP code, but some of our code is
using this header differently than the rest of the build system, and
hits this warning-turned-error:
error: "__USE_MINGW_ANSI_STDIO" is not defined [-Werror=undef]

Currently, /system/xbin/su is world executable. Prior to SELinux
enforcement, anyone (including third party apps) could run su.
The su code itself checks to see if the calling UID is root or shell.
Rather than relying on enforcement within the su binary, modify the
binary so it has group=shell, and remove world-execute permission.
This helps avoid some annoying SELinux denial messages as third party
apps call su on userdebug/eng builds.

Define a UID to be used by the process responsible for creating shared
RELRO files for the WebView native library, and create a directory owned
by that UID to use to store the files.

These headers are needed for pid_t and free when using libc++ headers (POSIX
does not require that the symbols be exposed with the previous includes).

Added definitons and structures for new audio routing features
in the framework and audio HAL.
The structures describe the objects needed to perform audio
routing and audio gain control: different variants of audio ports
and their corresponding configurations as well as gain controllers.
