In particular, Android targets use c_int whereas normal Linux targets
use c_ulong. An ioctl number should always fit in 16 bits, so casting
from c_uint (as bindgen uses for the constants) to either other type
should be safe.

This allows us to define const variables that are the return value of
the method, which we can then use in match statements.

The syslog and ioctl macros in sys_util were originally written to be
imported through `#[macro_use] extern crate sys_util` which is
essentially a glob import of all macros from the crate.
In 2018 edition, extern crate is deprecated and macros are imported the
same as any other item. As these sys_util macros are currently written,
importing an individual macro requires the caller to also import any
other sys_util macros that the invocation internally expands to.
Example:
use sys_util::{error, log};
fn main() {
error!("...");
}
This CL adjusts all sys_util macros to invoke helper macros through a
`$crate::` prefix so that the caller is not required to have the helper
macros in scope themselves.
use sys_util::error;
fn main() {
error!("...");
}

Some IOCTL macros are define to accept a parameter, EVIOCGBIT is an
example. This commit adds the ability to generate functions that
accept any number of arguments to generate the IOCTL number.
