MFC r289065: Add --currently-running <release> option to freebsd-update.

MFC r279571,281563 (allanjude):

Add a new safetly belt to freebsd-update to prevent a user doing a minor
update (-pX) while having an unfinished major upgrade (9.x to 9.y)
Safetly belt can be disabled with the -F flag

Additionally, add the --not-running-from-cron flag they bypasses the TTY
requirement, and allows freebsd-update to be invoked by orchestration
frameworks, scripts, or otherwise.

Add "IDS" command to freebsd-update. This was present in the original
version of freebsd-update, but I took it out when I rewrote everything
and added FreeBSD Update to the base system because I didn't think it
was useful. It turns out that quite a few people liked it and wanted
it back.

Add support for "freebsd-update -r newrelease upgrade" -- binary
upgrading to new releases. Important parts of this code include
* automatically determining which optional components (e.g., src,
info, proflibs) are installed.
* merging changes in files which are modified locally and have
changed between the currently running and new release.
* prompting the user to rebuild all 3rd party software before
deleting old shared libraries.

Yes, this is compatible with "freebsd-update rollback" -- you can
test a new -BETA and roll back to the old release if you don't
like it.

Subject to re@ approval, this will be MFCed before 7.0-BETA3 and
6.3-RC1.
