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

The SO_RCVBUFFORCE option requires the caller of uevent_create_socket()
to have net_admin capabilities.
Set platform default rcv/snd buffer sizes to 256kb that will always be
overridden by the device/target. However, it will allow
ueventd / healthd to use the uevent_create_socket() API w/o requiring
the net_admin capability.
Note: All devices override the buffer sizes according to the technology
maximum to at least ~8MB. So, the init.rc change here is to make sure
platform code can work w/o any overrides.
Test: no SELinux failures for healthd with 'net_admin' removed.

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.

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;
hidl_cb(..., fd_handle);
