rS348178: Move to using newvers -c instead of VARS_ONLY=1
rS348177: Convert freebsd-version to using -v
rS348176: Convert amd newvers to using newvers.sh -v.
rS348175: Implement "VARS_ONLY=1" via special command line args
Summary

This reduces the namespace pollution when used in this mode.

Convert amd newvers to VARS_ONLY mode

Rather than the tedious and error-prone grep of sys/conf/newvers.sh,
use the new VARS_ONLY mode to dig out the data that's desired.

Note: I've left the comment in newversh.sh for now. We'll revisit that
once I'm sure things have been sorted.

Convert freebsd-version to using VARS_ONLY

newvers.sh has supported a variable setting only mode, use that in
preference to grep to future proof this script from changes there.

Implement a better "VARS_ONLY" mode.

Add -v to print TYPE REVISION BRANCH RELEASE VERSION RELDATE variables
Add -V var to print var's value
Both of these in ${var}="${val}" format
Add -c to print the copyright text only.
Add -o to set VARS_ONLY=t, but this is viewed as a transient thing since
I'd like to eliminate that mode entirely.

A bunch of other changes to transition to VARS_ONLY

Test Plan
NOTE: This is a bunch of commits that I need to curate. I'm looking for a notion of where we're at at the end.

rebase, and remove the removal of VARS_ONLY. it's likely used outside of the tree.

guard against newvers.sh not being executable when invoking it.

The kernel invokes newvers.sh with sh, so do the same for all these instances. It has no 'x' bit in my tree.

Moving this breaks the default -R mode because ${modified} is not set at the time this is evaluated.
