deploy.sh: Move notify() to globals.sh

Extend `notify` to 4 variants:

- notify_i = inline (no newline) colored output;
- notify   = `notify_i` + trailing '\n';
- notify_n = `notify` + extra '\n' before and after;
- notify_e = `notify` + stderr output + exit;

This allows us to remove '\n' and cleanup the code a bit.
While at it, fix some 'NOTE' messages going to stderr instead of
stdout.
