Beyond changes to the build system, this includes fixing up the sample
freebsd.mc configuration for changes in defaults and syntax, removing
outdated documentation, and updating the release notes.
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.
of queuing mails only can be restored by uncommenting a CFLAGS+= line
in the makefile, so sites that _really_ need this (perhaps some huge
mail hubs) can still have it. The majority of FreeBSD boxes is better
served with an immediate delivery (and last time i've been asking on
the list, nobody complained).
