- provide in_domain() and in_site() functions to restrict usage:
need_string('foo.bar') -- allowed in both domain and site config
need_string(in_site('foo.bar')) -- only allowed in site config
need_string(in_domain('foo.bar')) -- only allowed in domain config
- need_* merge the domain and site configs while prefering the domain
values
PKG_FILE_DEPENDS caused the whole site repo to be hashed to determine if
gluon-site needed rebuilding. While this is normally no problem,
alternative build setups sometimes put the Gluon repo inside the site repo,
causing long build times and parallel build failures.
