CVS commit: [thorpej-cfargs] src/sys

["Jason R Thorpe" <thorpej%netbsd.org@localhost>]

Module Name:    src
Committed By:   thorpej
Date:           Sun Apr  4 19:12:28 UTC 2021

        src/sys/kern [thorpej-cfargs]: subr_autoconf.c
        src/sys/sys [thorpej-cfargs]: device.h

Log Message:
Add a CFARG_SEARCH tag, which specifies an indirect config search function
(which has the same signature as a direct config submatch function).  This
is a synonym for CFARG_SUBMATCH internally, but this is an implementation
detail; the two things should be distinct to callers, because submatch
and search functions have different behaviors.  Only one SEARCH or SUBMATCH
argument is allowed.

Also, change config_get_cfargs() to panic if an unknown tag is passed
(we don't know what kind of argument to consume after an unknown tag, so
this is fatal).
