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);

Replace references to cutils/log.h and log/log.h with android/log.h.
Point cutils/log.h to android/log.h. Adjust header order to comply
with Android Coding standards.

libhwbinder's Parcel::readNativeHandleNoDup returns a temporary
native_handle_t. We want a way to save the temporary handle for later
use.

User specified values of numInts and numFds can overflow
and cause malloc to allocate less than we expect, causing
heap corruption in subsequent operations on the allocation.
