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.
Test: builds, boots, tests pass

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.

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.

Add private function __android_logger_get_buffer_size() to read
properties and compose the default buffer size. This interface
complements the existing android_looger_get_size() which returns
the logd setting which can differ at runtime. For use in logd
and dumpstate. Side effect is we also add the private functions
__android_logger_property_get_bool() and
__android_logger_valid_buffer_size() for reuse in logd.

HIDL requires file descriptors to be wrapped in native_handle_t. We want
a low overhead way to do that when the number of file descriptors is known
at compile time. Instead of
// wrap an fd in native_handle_t
native_handle_t* fd_handle = native_handle_create(1, 0);
if (!fd_handle) {
// clean up and return error
}
fd_handle->data[0] = fd;
hidl_cb(..., fd_handle);
native_handle_delete(fd_handle);
this change adds native_handle_init to allow for
// wrap an fd in native_handle_t
NATIVE_HANDLE_DECLARE_STORAGE(fd_storage, 1, 0);
native_handle_t* fd_handle = native_handle_init(fd_storage, 1, 0);
fd_handle->data[0] = fd;

Allows us to mitigate the impact of MAP_PRIVATE and copy on write by
calling android_lookupEventTag_len instead of android_lookupEventTag,
and delaying the copy on write impact to the later. We return a
string length in a supplied location along with the string pointer
with android_lookupEventTag_len(const EventTagMap* map, size_t* len,
int tag). The string is not guaranteed to be nul terminated. Since
android_lookupEventTag() called even once can cause the memory
impact, we will mark it as deprecated, but we currently have no
timeframe for removal since this is a very old interface.
Add an API for __android_log_is_loggable_len() that accepts the non
null terminated content and fixup callers that would gain because the
length is known prior to the call either in the compiler or at
runtime. Tackle transition to android_lookupEventTag_len() and
fixup callers.
