To quickly answer the question of "how much data is a UID using?" we
need a GID range to label files on external storage, similar to
the GID ranges already defined for cached and shared data.
Also define a new GID that will be used to label the OBB files shared
between all users under /data/media/obb.

Some of Android componets e.g. init have migrated to use base/logging to get rid
of klog utilities. However, without explicit initilization, the default
klog_level is set to 3 which masks the logwrap output.
This patch sets default klog_level to KLOG_INFO_LEVEL to make
android_fork_execvp_ext log available.

If we're going to build libziparchive with _FILE_OFFSET_BITS=64, which
seems like a reasonable idea, we don't want off_t/off64_t mixups in the
ABI, and C++ name mangling helps protect against that where C wouldn't.

IF_ALOG_RATELIMIT()

static time_t last; /* initial state zero */
IF_ALOG_RATELIMIT_LOCAL(60, &last)
ALOGE("Only one message locally may appear every minute,"

These new calls are guaranteed not to affect the value of a
non-zero errno to simplify logging of errors. However, the
ALOGE calls in the above examples may update the errno value
upon their return.

To support upcoming disk usage calculation optimizations, this change
creates a new GID for each app that will be used to mark its cached
data. We're allocating these unique GIDs so that we can use
quotactl() to track cached data on a per-app basis.
This change also tightens up the implementation of both the cache
and shared GID calculation to ensure that they stay inside the valid
ranges, and includes tests to verify.

Currently, all internal media storage files (under /data/media) are
given the same "media_rw" GID. To support an upcoming optimization
to disk usage calculation, this CL defines three new GIDs that can be
used to quickly identify common types: audio, video, and images.

FileWriter::Create() calls ftruncate(2) to truncate the destination
file, which doesn't work with FD that references a block device. It
leads to kIoError when calling ExtractEntryToFile() to extract an entry
to block device FD.
As a result, it fails the package_extract_file() command in OTA updates
(e.g. 'package_extract_file("boot.img",
"/dev/block/platform/soc.0/f9824900.sdhci/by-name/boot")').
This CL skips the call to ftruncate(2) if FD references a block device.

Expand logprint feature to pull out the log tag description
fields, parse them and merge into the logging content. Add
-v descriptive, -v colour(british, hidden) and -v help. Also
added a unit test for the descriptive format borrowing from
event tags that have been unchanged since 2009.
Had to add -v help because we have too many undocumented
formats and format adverbs.

Solve one more issue where privilege is required to open a file and
we do not want to grant such to the service. This is the client side
of the picture, init is the server. The file's descriptor was placed
into the environment as "ANDROID_FILE_<path>" where non-alpha and
non-numeric characters in the <path> are replaced with _ and this
function picks the file descriptor up.
Added definition ANDROID_FILE_ENV_PREFIX ("ANDROID_FILE_") and
android_get_control_file() prototype in a new include <cutils/files.h>
android_get_control_file() checks if the resulting file descriptor is
valid, open and matches the name reference, which on purpose will fail
if a symbolic link is in the path rather than using a fully qualified
path. Add gTest unit test for both.

Native bridge implements namespace related interfaces in version 3.
The namespace semantic here is same as Android dynamic linker's.
Native loader wraps library loading functions of dynamic linker and
native bridge. Thus, Android runtime is able to load native library
of different ISA on one device by calling native loader directly.
