Matt Layher 79b0c68887 unix: add Linux block device ioctl types and constants 
These types and constants are taken from hdreg.h, and will enable
querying and manipulation of block devices on Linux.

Matt Layher ab9e364efd unix: add generic netlink types and constants on Linux 
Generic netlink is a generalized netlink family which enables a series
of different communication channels to be multiplexed on a single
netlink family.

Matt Layher 2d6f6f883a unix: add taskstats enum values 
I falsely assumed that enum values would be generated automatically,
but now realize that the previous values I added were actually generated
from preprocessor define statements.

This change adds some missing values I intended to add in CL 59050.

Fixes golang/go#21623.

Matt Layher a55a760868 unix: add IoctlGetInt and IoctlSetInt on Linux 
This CL adds basic integer get/set functions which wrap a generic
ioctl call.  The API is similar the one introduced for solaris/amd64
in CL 14587, but the request parameter has been changed to a uint
instead of an int.  This makes requests with a number larger than the
maximum signed 32-bit integer work on linux/386.

For consistency, the solaris/amd64 API has also been updated to make
use of a uint instead of an int for the request number.

Fixes golang/go#20474

"When the client creates a connection, instead of providing an IP address
