Use IOCONF #define to determine component name.

Avoids having to manually retype info already in .ioconf.

Also, COMPONENT_SIMPLE -> RUMP_COMPONENT=simple. That way, we can add
other attributes where necessary. As "future directions", the "ioconf"
attribute for RUMP_COMPONENT can just be removed when a driver is
converted to modular and has a proper modcmd.

Make it easier to create rump kernel components, part 1.

Reduce copypasteware for the component constructors. If a constructor
calls only config_init_component(), handle it from a common source file
instead of copying the same(ish) file around to every component.

Add a COMMENT describing what each component roughly does.

"make describe" prints the comment.
