__FBSDID() additions
some include file sorting.
Some Makefile sorting.
WARNS?=2 is not added to the Makefile, because it is going to be
default for usr.bin/
NO_WERROR is set because there are rpc*.h file issues.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
