Currently the only way to have one setting copy value from other setting is to
do as follows:
```
syscfg.vals:
FOO: 'MYNEWT_VAL_BAR'
```
The problem with the above is that `newt` handles value of `FOO` as a string
which is then resolved by preprocessor during build so this won't evaluate
properly if used inside `syscfg.restrictions`
This PR allows one setting value to explicitly reference other setting and have
other value copied by `newt`. The syntax is very simple:
```
syscfg.vals:
FOO: '@BAR'
````
For now it does not support recursive references and there's no nice way to
escape `@` if an actual value should start with `@` (perhaps prepending `@`
with space would work as a workaround...) but I think we can live with it until
I can figure out how to do this in Go ;-)
